What fertilizer should I use to grow strawberries? Introduction of fertilization methods for Strawberry planting

Strawberry is a perennial herb of the genus strawberry in Rosaceae. The stem is lower than or nearly equal to the leaf, densely yellow pilose, flowers in Cymes, fruit in aggregate fruit, widely cultivated in various parts of our country, rich in nutrition, containing a variety of nutrients and health care effect. With high cultivation value, let's take a look at what kind of fertilizer strawberries use!

Do strawberries need a lot of fertilizer?

Strawberries blossom and bear fruit continuously, and more fertilizer is needed from planting to flowering and fruiting. In addition to applying sufficient basic fertilizer, strawberry fertilizer or diammonium phosphate can be applied to 10 kg per mu during fruit expansion and harvest period. The effect of ditch application in the form of 200 times liquid fertilizer combined with watering is better, and the fields with good growth are only sprayed with 0.1-0.2% potassium dihydrogen phosphate for 3 times, which also has a certain effect on increasing production, and it is not sprayed in principle during flowering. The principle of fertilization in fruit harvesting field is suitable N weight P and K, and a reasonable proportion relationship must be maintained in order to obtain higher yield and maximum benefit.

What kind of fertilizer is good for strawberries?

1. Nitrogen fertilizer: nitrogen fertilizer can promote the growth of strawberry seedlings. Beans, peanuts and melon seeds that have been moldy and cannot be eaten are good raw materials for nitrogen fertilizer.

2. Phosphate fertilizer: phosphate fertilizer can make strawberries colorful, bright and plump, such as fish bones, eggshells, meat bones and so on.

3. Potash fertilizer: potash fertilizer can improve the resistance of strawberries to diseases and insect pests. Amoy rice water, leftover tea water and milk bottle water are all good raw materials for potash fertilizer.

How to fertilize strawberries?

1. Base fertilizer: before planting strawberries, the soil should be ploughed 25cm deep, and 450 kilograms of commercial organic fertilizer or 3500 kilograms of high-quality farm manure, 5 kilograms of urea, 15 kilograms of diammonium phosphate and 6 kilograms of potassium sulfate should be applied.

2. Topdressing: from the beginning of strawberry growth to before flowering stage, urea 9kg and potassium sulfate 4kg / mu were applied, and 11kg / mu urea and 7kg potassium sulfate were applied during berry expansion period. After a large number of fruits, topdressing can be carried out as needed.

3. Leaf fertilizer: spraying humic acid organic-inorganic liquid compound fertilizer on strawberry leaves before and after flowering can increase fruit setting rate, improve fruit quality and increase single fruit weight. Spraying 0.2% calcium sulfate and 0.05% manganese sulfate at early flowering and full flowering stage can improve yield and fruit storage performance.

What fertilizer is good for strawberries?

Strawberry is a very beautiful fruit, red appearance is also dotted with a lot of light green dots. Strawberry has sweet taste and high nutritional value, so it has become one of the fruits that people especially like to eat. So do you know how strawberries are grown? What kind of fertilizer is used to grow strawberries?

What fertilizer is good for strawberries?

1. In order to improve soil fertility and mature the soil, strawberry should be ploughed 25-35cm deep before planting, and 450500kg of commercial organic fertilizer or 3500-4000 kg of high-quality farm manure, 5-6kg urea, 15-20kg diammonium phosphate and 5-6kg potassium sulfate should be applied.

2. Topdressing in order to meet the needs of various nutrients for flowering, 9-10 kg of urea and 4-6 kg of potassium sulfate were applied per mu after the beginning of strawberry growth and before flowering stage. Topdressing during berry expansion period: 11-13 kg of urea and 7-8 kg of potassium sulfate per mu. After a large number of strawberry fruit, there is a lack of nutrients in the plant. In order to restore plant growth as soon as possible and form new leaves and new roots, topdressing can be carried out as needed.

3. According to the growth situation of strawberry, extra-root topdressing (foliar spraying) can be used to assist fertilization. Foliar spraying humic acid organic inorganic liquid compound fertilizer before and after flowering can increase fruit setting rate, improve fruit quality and increase single fruit weight. Spraying 0.2% calcium sulfate and 0.05% manganese sulfate at early flowering stage and full flowering stage can improve yield and fruit storage performance.

Methods of growing strawberries

1. Strawberries are suitable for growing in sunny and hydrophobic soil. The depth of the soil is about 15 mi 20 cm.

2. For strawberries of large type, the row spacing should be 30 cm, and the plant spacing should be about 45 cm. 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.

3. If you don't like managing strawberries, you can plant strawberries every 45,000cm 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.

4. In autumn, cover the plant with a layer of soil to prevent frost. After the soil is frozen, you can spread hay 5-10 cm thick on the plant. 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.

Disease prevention and cure

1. Leaf spot disease: also known as snake eye disease, mainly harming leaves, petioles, fruit stalks, tender stems and seeds. Small dark purple spots are formed on the leaves, which are enlarged to form near-round or oval disease spots, with purple-red-brown edges, gray-white center and slightly fine wheels, so that the whole disease spot is snake-eye-like, and small black grains are not formed on the disease spot.

Prevention and control measures: timely removal of diseased leaves, old leaves. The initial stage of the disease with 70% chlorothalonil wettable powder 500 ~ 700 times liquid, ten days later spray again. Or spray 75 kg of water with 70% mancozeb wettable powder, 200 grams per mu.

2. Powdery mildew: mainly harmful to leaves, but also to flowers, fruits, fruit stalks and petioles. The leaves are rolled up in the shape of a spoon. The flower buds and petals are purplish red, can not bloom or bloom completely, the fruit is not inflated, is slender, and the young fruit loses luster and hardens. Near-ripening strawberries will lose their commercial value when they are damaged.

Control measures: focus on spraying Baume 0.3 degree stone sulfur mixture in and around the disease center strain. After harvest, the leaves of the whole garden were cut and sprayed with 1000 times of thiophanate methyl or 5000 times of methamphetamine and 5000 times of Teflin.

Nutritional value of Strawberry

Strawberry has high nutritional value and contains a variety of nutritional elements, such as amino acid, fructose, sucrose, glucose, citric acid, malic acid, pectin, carotene, vitamin B1, B2, nicotinic acid and mineral calcium, magnesium, phosphorus, potassium, iron and so on. These nutrients play a good role in promoting growth and development, and are of great benefit to the elderly and children.

At the same time, strawberry is also a kind of fruit with high vitamin C content. Strawberry contains vitamin C 50-100 mg per 100 grams, which is more than 10 times higher than that of apples and grapes. Vitamin C can eliminate the relaxation and tension between cells and make the structure of brain cells firm. Skin is delicate and elastic, which has an important impact on brain and intellectual development. In addition, the carotene in strawberry is an important substance in the synthesis of vitamin A, which has the function of eyesight and nourishing the liver. The latest foreign research also pointed out that strawberries contain an amine substance, which has a certain effect on the treatment of leukemia and aplastic anemia.

Foreign scholars have found that the active ingredients in strawberries can inhibit the growth of cancer. Therefore, eat some strawberries after meals, can decompose food fat, conducive to digestion at the same time, but also play a certain role in preventing cancer!

Through the above, we learned about the planting technology of strawberries. Strawberry delicious nutrition, the use value is also very high, can make strawberry dessert, strawberry candy, strawberry biscuits, dried strawberries, eating methods are also very many. So isn't growing strawberries considerable?

When should home-grown strawberries be fertilized best and what kind of fertilizer should they need?

The day at the end of April can be regarded as neither hot nor cold. There is no cold in winter and hot in summer. I would also like to remind you that Labour Day short holiday is coming! Today, I am in a good mood to bring you to talk about how to apply fertilizer after strawberry planting is also a question that flower friends have asked me recently. With your questions, I will find out when and what fertilizer should be applied after strawberry planting.

When is the best time to apply fertilizer?

First, base fertilizer

Before soil preparation, sprinkle and then plough, ridge, apply 3-5 mu of rotten chicken manure or cow manure organic fertilizer, and apply 15-15-15 nitro-sulfur compound fertilizer 100 kg.

Second, topdressing for the first time

After the survival of the seedlings, topdressing was carried out when the two leaves were spread out to promote the early development of the seedlings, promote the vegetative growth of the plants, and lay the foundation for flower bud differentiation. The application of 15-15-15 nitro-sulfur compound fertilizer per mu is 20 jin. The method of fertilization is shallow ditch or hole application or fertilizer dissolved in water.

Third, the second topdressing

The second fertilizer was applied before and after buckling the shed, and 18-9-18 nitro-sulfur compound fertilizer was applied to 20-30 jin per mu.

Fourth, follow-up topdressing

During the fruit expansion period, 35 jin of thio-19-4-22 polypeptide fertilizer or 16-8-21 compound fertilizer was applied per mu to prevent premature senescence. It can be applied with the water, ditched and buried, and chased every half a month.

Foliar topdressing strawberry can be sprayed with foliar fertilizer from bud growth to fruit development, combined with spraying half.

What kind of fertilizer do strawberries need

Generally speaking, nitrogen fertilizer can promote the formation of a large number of leaves and stolons, strengthen vegetative growth, increase fruit number, nitrogen deficient leaves will turn yellow, partially scorched and slightly smaller than normal leaves, phosphate fertilizer can promote flower bud differentiation and increase fruit setting rate. the appearance of the upper leaves of phosphorus deficiency showed purple spots, flowers and fruits were small, potash fertilizer mainly promoted fruit ripening, increased fruit sugar content and improved fruit quality. The edges of potassium-deficient leaves often appear black, brown and dry, and when serious, they become burns, the old leaves suffer seriously, the fruit is light in color and taste is poor, in addition, strawberries are very sensitive to chlorine, so the use of chlorine-containing fertilizer should be controlled.

2. Potted strawberries fertilize potted strawberries it is best to apply sufficient basal fertilizer before planting. Strawberries should be fertilized reasonably during the growth period to ensure that the plants grow healthily, with more blossoms, more fruits, and large fruits. There are many choices of base fertilizer, such as long-acting slow-release fertilizer, and other organic fertilizers.

It is estimated that the reasonable topdressing of strawberries is the most chosen by flower friends, because most flower friends have forgotten the base fertilizer. in order to meet the needs of various nutrients during the flowering and fruiting period of strawberries, general fertilizer can be applied from the beginning of strawberry growth to before flowering period. if base fertilizer is used, no fertilizer can be applied, and fertilizer with high nitrogen and potassium can be applied during the expansion period of strawberry berries. after a large number of strawberries bear fruit, the plant is lack of nutrients. In order to restore plant growth and form new leaves and roots as soon as possible, topdressing should be carried out as needed.

All right, that's all for today. I hope flower friends will get something after reading this article. If you want to know more about the conservation of cultivation techniques, please continue to follow our succulent flower beds, and we will provide you with more related content!
