Introduction to the price and planting methods of peanut seeds

Peanut is a kind of widely edible nut, also known as peanut, evergreen fruit, muddy bean, etc. it is an annual herb of the genus Peanut of Leguminosae, with rich root nodules and erect or creeping stems. It is widely cultivated in various parts of our country. It is suitable for sandy soil areas with warm climate and moderate rainfall, and the growing season is longer. Let's take a look at the seed price and planting methods of peanuts.

How much is the peanut seed per jin?

The price of peanut seeds is about 810 yuan per jin, but it varies greatly due to the quality, variety, producing area and market of peanut seeds. Peanut cultivation is very common in China, usually one mu of land needs about 20 jin of peanut seeds, one thousand holes per mu, two to three grains per mu, the yield per mu is about 600 jin, and the high-yield field can be close to 800 jin.

What kinds of peanuts do you have?

1. Common type: the pod shell is thick, the vein is smooth, the pod is cocoon-like, there is no keel, and most of the seeds are oval, which is the main cultivated variety in our country.

2. Bee waist type: the pod shell is very thin, the vein is remarkable, there are keels, there are more than three seeds, sometimes there are two grains, and the seed coat is dull and dull.

3. Multi-grain type: there are many seeds in the pod, showing a string of beads, the shell is thick, the vein is smooth, the seed coat is red, sometimes white.

4. Pearl type: the pod shell is thin, the pod is small, generally two seeds, the kernel rate is high, the seeds are full, most of them are pick-shaped, and the seed coat is mostly white.

Sowing method of Peanut

1. Sowing time: the optimum temperature for peanut flowering is 23: 28 ℃, the lowest temperature is 19 ℃, the optimum temperature for pod setting is 25: 30 ℃, and the lowest temperature is 15 ℃. Sowing time should be arranged reasonably according to local air temperature and local sowing habits, and suitable sowing time is beneficial to high yield.

2. Sowing method: the sowing method of peanut is sown in the open field and covered with plastic film according to the cultivation method, and the planting density is determined by plant height, fruiting range and leaf area. planting density depends on climate characteristics, soil fertility, selection of varieties and cultivation conditions.

3. Sowing depth: the sowing depth of peanuts should be about 5 cm. It is necessary to grasp the principles of "dry is not deep, wet is not shallow" and the soil is shallow, sandy land or sandy land should be deep. The deepest cultivation in open field should not exceed 7 cm, and the shallowest should not be less than 3 cm.

4. Post-sowing suppression: peanut post-sowing suppression is an effective way to resist drought and sow peanuts to ensure the whole seedling. Suppression can not only reduce soil water evaporation, but also make seeds in close contact with the soil, promote the rise of soil moisture and prevent drying. It is easy for seedlings to germinate.

Planting methods of Peanut

1. Check seedlings and replenish seedlings: peanut seedlings should be checked in time after emergence, and seedlings should be replenished in time where there is a serious shortage of seedlings, so that the number of seedlings per unit area can reach the planned number, which is generally carried out 3-5 days after emergence.

2. Clear and strong seedlings: when peanut seedlings are ploughed for the first time, peanut seedlings are ploughed with a small hoe to strip the soil around the peanut seedlings, so that two cotyledons and the first pair of lateral branches are exposed to the soil, so that the first pair of lateral branches can develop healthily and make the seedlings grow vigorously.

3. Irrigation and drainage: peanuts are afraid of both drought and waterlogging. The irrigation period is mainly determined by the amount and distribution of precipitation during the peanut growth period, soil water content and the need for soil moisture at each growth stage of peanut.

4. Moderate prevention and control: about 30 days after flowering, in order to prevent the overgrowth of the plant, when the plant grows too much and the field is closed prematurely, the foliar spraying of paclobutrazol can increase the yield by 10%.

5. Disease and pest control: peanuts are susceptible to leaf spot disease and peanut rust. Leaf spot disease uses 75% topiramate 1000 times or 50% carbendazim 800 × 1000 times 70 kg 80 kg per mu, and peanut rust uses 20% trimethoprim EC 30 ml to 40 kg water per mu.

When will peanuts be planted? Introduction to planting time and methods of Peanut

Peanut planting time

Under normal conditions, peanuts should be planted from the end of April to the first ten days of May.

Little knowledge of peanut planting

1. Leveling the land

Peanuts are cash crops that blossom on the ground, form fruit needles and drill into the ground to bear fruit. Suitable for planting on loose sandy soil and oil sandy soil. The plots for growing peanuts should be deeply turned over, combined with 30-40 tons of high-quality farm manure per hectare, and suppressed 1-2 times after turning. Where there are conditions, water can be irrigated first, and then agricultural fertilizer and chemical fertilizer can be mixed into ridges and furrows, ridging and suppression, so as to prepare for sowing at the right time. Note that peanuts like stubble, should not be repeated and welcome stubble. The better previous crops are corn, millet and sorghum.

two。 Cultivated variety

Improved varieties are the basis for high yield of peanuts. The peanut varieties suitable for planting in this area mainly include Fuhua series varieties and Jifu series varieties (commonly known as Sijiehong). The growth period is about 120 days. Choose pods that are big and full, neatly shaped and unbroken as seeds. The seeds should be dried for 1-3 days before shelling, and the seeds with pure color and neat shape should be selected as seeds after peeling.

3. Scientific fertilization

Peanuts are relatively resistant to barren, fertilization should be based on base fertilizer, 30 tons of farm manure per hectare, chemical fertilizer should be based on phosphate fertilizer, 300-400 Jack diammonium phosphate per hectare. Grow peanuts in barren land and apply 200-300 jin more urea per hectare.

Stratified fertilization: the fertilizer applied before sowing should be divided into two layers: base fertilizer and seed fertilizer.

Step-by-step fertilization: it mainly refers to the step-by-step fertilization technology of the combination of base fertilizer, seed fertilizer and topdressing fertilizer for available nitrogen fertilizer. The available nitrogen fertilizer should be based on base fertilizer and seed fertilizer, and a certain amount of urea or other fertilizer should be applied in time if the phenomenon of de-fertilization occurs in the process of growth.

Deep fertilization: the basic fertilizer should be applied to the planting of 8 mures 10 cm, the seed fertilizer should be applied to the planting of 3 murals of 5 centimeters, and the topdressing depth should reach more than 10 centimeters.

4. Timely sowing and reasonable close planting

The suitable sowing time for peanuts in this area is the first and middle of May, and the specific sowing time depends on the weather conditions. The principle is that as long as the surface temperature of 5 cm stably passes through 12 ℃, the peanuts can be sown with 3-4 grains per grain and 3-5 cm thickness of soil cover, and the second is to sow seeds on demand. If the soil moisture is insufficient, it must be planted by sitting on water. When using sitting water seeds, we must wait for the water to seep completely before fertilizing, sowing, covering soil and other links.

Before sowing, peanuts should be soaked in warm water (two cool to one open) for 3-4 hours, moisturized, put in a place of 20-25 ℃ to sprout, sprout after one day and night, and sow the seeds on wet soil when sowing to prevent the buds from drying. Germinating seeds should be sowed at any time and should not be sown overnight, lest the buds grow too long and damage the germ. Generally speaking, the fertile land should be sparse and the thin land should be dense, and the suitable sowing density in this area is 15-200000 plants per hectare, and the suitable sowing density of each piece of land should be determined according to the soil fertility and the density tolerance of varieties.

Introduction to the price and planting method of mini water lily seeds

Mini water lilies are perennial aquatic plants of the family Nymphaeaceae, which have high ornamental value. How much are the seeds of mini water lilies? Now let's take a look at the seed price and planting method of mini water lilies.

How much is the mini water lily seed?

Mini water lily seed price list:

Variety specification reference price

Number one red 30 tablets / package 1 yuan 2 yuan 30 Baolian lanterns / bag 1 yuan 2 yuan

30 pieces of purple fragrant lotus, 1 yuan per pack, 30 tablets of Athena, 1 yuan per pack.

30 Xuemei 30 tablets / package 1 yuan 2 yuan 30 new imperial concubines 1 yuan / bag 1 yuan

Note: mini water lilies are a general term for a smaller class of plants in water lilies. There are many varieties, usually named according to different flower patterns, but the prices of different varieties are not much different. The above prices are for reference only. Please take the actual price as the basis for purchase.

Sowing methods of mini water lilies

1. Sowing time: the seeds of mini water lilies have no dormancy period. As long as the water temperature can be kept above 16 ℃, they can be sown in four seasons. Under suitable temperature and light, it takes 50-60 days from sowing to flowering in spring and 60-80 days in autumn.

2. Seed treatment: the shell of the mini water lily seed is hard and dense. Before soaking the seed, it must be artificially broken, and the small concave end is worn out and worn out a layer of skin on the rough cement floor. Do not hurt the kernel inside, and do not remove the shell. Make the seed absorb water and expand.

3. seed soaking to promote germination: the broken seeds of mini water lilies are soaked in warm water of about 20-40 degrees. A small amount of seed soaking in the family can be put into a thermos to keep warm. Generally, seed soaking for 3-5 days can germinate, and the germ protrudes from the break.

The planting method of mini water lilies

1. Transplanting: mini water lilies are planted in pottery pots or plastic flowerpots with a diameter of 45cm and 75cm without bottom holes, in which half a pot of pastoral soil or river pond mud is added. When transplanting, press the fine roots of small lotus seedlings into the mud, one plant in each pot, and add appropriate amount of water after transplanting, so that the lotus leaves will not be submerged.

2. Moisture: the amount of water irrigated in different growth stages of mini water lilies is also different, so it is not appropriate to have too much water at the first planting. Too much water will hinder the growth of young roots and lead to rotten roots. When the leaves grow up, water will be irrigated gradually, and water will be watered once in the morning and evening in summer.

3. Fertilization: before planting mini water lilies, a small amount of rotten cake fertilizer liquid or bean bran and peanut bran should be mixed into the pot soil as base fertilizer, but not excessive fertilization. generally, a small amount of cake fertilizer and other base fertilizer can be mixed into the culture soil to meet its needs for the whole year.

4. Lighting: mini water lilies like plenty of sunshine. If the light is less than 4 hours a day, they can't form flower buds. During the birth period, it should be placed on the sunny balcony or windowsill to the sunny place, so that it can receive all-day sunshine. Appropriate shade is needed around noon in summer and early autumn.

5. Pruning: when the leaves of mini water lilies grow too much and too dense, you can appropriately remove some of the leaves to facilitate the breathing of the plants and help the flowers. If you find that the leaves compete for strong sunlight when using the same container for breeding, it should be cultured in pots in time.
