How much is the strawberry seed per jin? How do you plant it?

Strawberry, also known as raspberry, is a kind of perennial herbal fruit, which is loved by many people because of its high nutritional value, strengthening gums and preventing constipation. Many growers also want to grow strawberry seeds. How much is strawberry seed per jin? How do you plant it?

How much is the strawberry seed per jin?

The price of strawberry seeds varies, but on the whole, some people think that it is still quite expensive. In general, the market price of strawberry seeds per jin is about 80-1200 yuan, but the number of seeds per jin is about 100000. Usually only one jin of seeds per mu is needed, if calculated in this way, the price of strawberry seeds is actually not expensive. In fact, strawberry seed propagation is mostly used for long-distance introduction or cultivation of strawberry seedlings to select new varieties, but it is also often used for courtyard greening and fresh food planting. Strawberry sowing and breeding is mostly carried out in the following spring, but it can also be carried out from July to August of the year in which the seeds are collected.

Second, how to plant strawberry seeds?

1. Seed collection

During the fruit harvest from May to June, the well-developed and fully ripe fruit was selected for seed collection, peeled and washed in water to remove the slurry to dry, or the peel was directly dried and then crushed, in which the pericarp and seeds can be separated.

2. Seed treatment

Wash strawberry seeds in 60-70 ℃ warm water and keep stirring until the water temperature drops to about 25 ℃. After soaking for 2-3 hours, remove and rub until the seed coat is clean and glossy, then rinse with clean water and cover with several layers of wet gauze under 25-30 ℃ conditions for germination. Soak the gauze in warm water three times a day in the morning, afternoon and evening to keep the seeds moist. The seeds can be sown after 60-70% of the seeds are exposed to white.

3. Sowing method

Before sowing strawberry seeds, irrigate the border with small water and rake the border surface with a rake. When the border seeps under water, the strawberry seeds can be planted. It is better to sow strawberries with small seeds, and the sowing rate is 2.5-4.5g per square meter. Immediately after sowing, spread the prepared mulch soil evenly on the border surface and cover the border with a thickness of 0.3-0.5cm and shade with straw mats and scatter the seedlings.

4. Seedling land preparation

Strawberry nursery land selects fertile soil and applies sufficient base fertilizer, which is dried with manure and then mashed and applied to the seedling land that has yet to be ploughed. The amount of fertilizer is 5-10 jin per square meter, and compound fertilizer should be added appropriately. After fertilizing, careful ploughing should be carried out, and the depth can be about 33cm. After ploughing, rake and rake flat and ridge according to the specification of 0.8-1m wide * 8-10m long to make the border horizontal to facilitate drainage, irrigation and management.

5. Seedling stage management

Strawberry seedlings are not suitable for flood irrigation, but sprinkler irrigation can be used to meet the water supply. Small water flooding irrigation can be used after 6 true leaves. Strawberry seedlings should often pull out weeds in time. Strawberry seedlings can be transplanted when they grow 3-5 true leaves, and when strawberry seedlings grow to 6 true leaves, they can be fertilized for the first time and urea should be applied.

Summary: the above is the introduction of strawberry seed prices and planting methods, it should be noted that the above strawberry seed prices are for reference only, specific should be based on the actual price, hope to help friends in need!

Collection, treatment and sowing methods of Strawberry Seeds

Strawberry is a perennial herb of the genus strawberry in Rosaceae. The propagation methods include seed propagation and plant division propagation, which are often used in production. Seed propagation is more often used for long-distance introduction or cultivation of strawberry seedlings to select new varieties. It can also be used for courtyard greening and fresh food planting. Let's take a look at the planting method of strawberry seeds.

Seed collection

During the fruit harvest from May to June, the well-developed and fully mature fruits were selected for seed collection, peeled off, put into water, washed, removed and dried. Or dry the peel directly, then crush it, and then separate the peel from the seed.

Seed treatment

Wash the strawberry seeds in 60-70 ℃ warm water and keep stirring until the water temperature drops to about 25 ℃. Soak for another 2-3 hours, remove and rub with hands until the seed coat is clean and shiny. Then rinse with clean water and cover with several layers of wet gauze. Germinate under the condition of 25: 30 ℃, soak the gauze with warm water three times a day (morning, noon and evening) to maintain the moist environment of the seeds, and sow seeds after 60: 70% of the seeds are white.

Sowing method

Before sowing strawberry seeds, irrigate the border with small water, then rake the border surface, and then sow when the border seeps under water. The seed of strawberry is small, so it is better to sow it. The appropriate sowing rate is 2.5-4.5 grams per square meter. immediately after sowing, spread the mulch evenly on the border surface with a thickness of 0.3-0.5 cm, shade with straw mats and scatter after finishing the seedlings.

Seedling land preparation

Strawberry nursery land is selected from fertile soil and applied sufficient base fertilizer, which is dried with manure, and then mashed and applied to the seedling field that has yet to be ploughed. The amount of fertilizer applied is 5 jin per square meter, and compound fertilizer should be added appropriately. After fertilizing, careful ploughing should be carried out, and the depth can be about 33 cm. After ploughing, it is necessary to rake fine and flat, and make ridges according to a width of 0.8 meters and a length of 8 meters, so as to make the border horizontal, so as to facilitate drainage and irrigation and management.

Seedling stage management

1. Watering: strawberry seedlings are not suitable for flooding irrigation, sprinkler irrigation can be used to meet the water supply, and small water flooding irrigation can be used after 6 true leaves.

2. Weeding: strawberries should always pull out weeds in time at the seedling stage.

3. Replenishing seedlings: strawberry seedlings can be transplanted with 3 or 5 true leaves.

4. Topdressing: when strawberry seedlings grow to 6 true leaves, topdressing can be carried out for the first time, and urea is suitable for topdressing.

How are strawberries grown?

How are strawberries grown? Do you plant it with seeds?

A friend asked if the cubs on strawberries could be planted. Yes, but only ripe strawberry seeds can buy strawberry seeds on the market.

In general, strawberries can be grown without seeds, split roots, and propagated stems grown with strawberries. And strawberry reproduction is relatively fast, a strawberry can reproduce a few flat aspects in a year.

General planting

one. Strawberries are suitable for growing in sunny, hydrophobic soil. The depth of the soil is about 8 mi 10 inches.

two. For large strawberries, the row spacing should be 12 inches and the plant spacing should be about 18 inches. The vines of the plant should be removed in time to facilitate the fruit of strawberries. The yield of strawberries is periodic, so it is best to cultivate some new plants in the first few years of planting.

three. If you don't like managing strawberries, you can plant strawberries every 18mur24 inches so that strawberries can grow everywhere. Of course, it will look a little messy, and the strawberries are not big. If you want to avoid this situation, you can remove some vines properly.

four. In autumn, cover the plant with a layer of soil to prevent frost. After the soil is frozen, the plant can be covered with hay 4 inches thick. In the spring of the following year, when new leaves grow, the hay is removed. After the weather becomes warm and stable, the covered soil on the surface of the plant is removed. But leave some hay between the rows to prevent the growth of weeds and retain moisture in the soil.

Greenhouse planting technology

Strawberry ranks first in the production of small berries in the world. Strawberry is an economic crop with quick fruit, early maturity, easy reproduction, short cycle and high benefit.

I. preparation of breeding grounds

1. Choose paddy fields with convenient drainage and irrigation, which are not easy to accumulate water and have high fertility, or vegetable garden soil (former crops and soil blocks that have used Lvhuanglong herbicide). Apply sufficient basic fertilizer (cake fertilizer, household fertilizer, human feces and urine, phosphate fertilizer) after ripening, at the same time, use 50% phoxim or 3% furan per mu, mix 25 jin of fine soil, and turn the soil to make a bed. The bed is 1.5 mi 1.8 meters wide and the turtle's back is shaped to prevent stagnant water and the soil should be broken.

2. Selection and planting of each plant. Select the new leaves to develop normally, the leaflets are symmetrical, the leaf color is dark green, the petiole is thick, the leaves are large, the growth is strong, the yield is good, and the diseased leaves and old leaves are removed. Our city is generally planted in the breeding ground in April of the Gregorian calendar (the daily average temperature is above 12 ℃). Two rows were planted in each border, 30 cm away from the edge of the border, and the distance between plants was 60 mi 80 cm. Immediately after planting, water the plant and fix it.

3. Fertilizer and water management, the principles of fertilization in seedling land are as follows: suitable nitrogen, heavy phosphorus and potassium, 200 jin of rotten vegetable cake plus 8 jin of urea per mu, 50 jin of phosphate fertilizer and 10 jin of potash fertilizer, and watering every 20 days after dissolving water. Human feces and urine can also be replaced.

4. After each plant survived (a week later), gibberellin (920) was sprayed, that is, each gram of "920" was mixed with 40 jin of water, (920 was first used with high concentration.

The spirit dissolves in a clean bowl) spray. Spray twice at intervals of one week to 10 days. The application of nitrogen fertilizer should be strictly controlled in August to make it drought properly, but not too much.

2. Preparation and specification of timely transplanting and transplanting land

1. Field preparation: choose fertile and convenient fields or soil for field use. Strawberries need a large amount of fertilizer, and there is generally less fertilizer in the later stage (harvest period), so the base fertilizer should be sufficient, and it should be dominated by organic fertilizer, generally 1500 tons per mu of organic fertilizer, 50 tons of cake fertilizer, 25-30 tons of compound fertilizer, 7.5 grams of urea, 40 grams of excess calcium and 10 grams of potash fertilizer. in addition to urea and compound fertilizer, other fertilizers, except urea and compound fertilizer, mix well with urea and compound fertilizer to spread the soil surface, and then turn the soil to make ridges. Generally, the height of the ridge is 25 tons, the width of the bottom of the ridge is 90 tons, and the surface of the ridge is 60 inches. The width of the ridge and trench is 30 cm, and the width of the furrow at the bottom of the ridge is about 100m / w. There is a certain inclination from the surface of the ridge to the bottom of the ditch.

2. Planting period and method: the protected cultivation in our city is generally transplanted from the end of September to the beginning of October. The planting density and seedling condition, soil fertilizer and thinness were treated separately, and strong seedlings, dry seedlings and soil fertilizer should be sparsely planted. On the contrary, it should be closely planted. Generally, 9,000 plants are planted in 7 mu. After the ridge is planted, it will be planted 5 cm from the edge of the ridge, with a distance of 12 cm to 15 cm. The length of the ridge generally does not exceed 30 meters.

Attention should be paid when transplanting: first, directional transplanting: both bow back outward, which is beneficial to the extraction of inflorescences later. Second, double-row triangular (zigzag) planting, which is conducive to ventilation and light to take root. The third is to grasp the depth so that the roots are not exposed and the seedlings are not buried at the top, which is beneficial to tillering. Fourth, transplanting with soil is beneficial to survival. Fifth, it will be planted in the afternoon on sunny days and all day on cloudy days. Sixth, strengthen the management of water and fertilizer, immediately pour through the fixed root water after planting, and add methyl topiramate according to 800 times liquid when watering. Seventh, check and replenish seedlings in time.

III. Field management

1, pre-winter management, after planting survived to mid-late November, we should pay attention to three points: first, frequent application of thin fertilizer, mainly nitrogen fertilizer, preferably dilute manure water; second, keeping moist; third, weeding and loosening soil to pick old leaves and diseased leaves.

2. Management before and after flowering: control diseases and insect pests with topiramine, trimethoprim, dimethoate, etc.

3. Overwintering management: before the cold winter comes, water should be poured thoroughly to prevent the cold.

4. cover the film at the right time

Plastic film mulching can double the yield, reduce fruit loss and prevent pollution. The film is divided into greenhouse cover film and mulch film. The time of covering the film should be controlled when the daily average temperature drops to about 8 ℃. First cover the greenhouse film, then cover the plastic film. Weeding, ploughing and fertilization should be done before mulching to control diseases and insect pests. (greenhouse production and film purchase model) due to limited space will not be introduced, interested parties please contact the Agricultural Science Institute. After covering the film, the temperature in the shed should be kept at 8 ℃ at night and about 20 ℃ during the day. The film should be lifted at noon on a sunny day and covered at 3 p.m. If the temperature is too high, the pollen dies, and the activity of the pollen is not enough to pollinate.
