Edamame needs to be fertilized several times from flowering to fruiting

<> fertilization methods and fertilizer selection for growing edamame.

In China, the demand for edamame in autumn is large, so edamame is mostly planted in May every year, and then harvested in August-September, and then marketed.

When growing edamame, in order for it to grow better, it should be fertilized properly. About a month or so before planting edamame, the soil should be deeply ploughed. Then the bottom soil is turned out and placed in the sun for disinfection and sterilization.

And apply some base fertilizer to the soil, you can choose human and animal manure.

Edamame has nitrogen-fixing bacteria in its roots, so it requires less nitrogen fertilizer and more phosphorus and potassium fertilizer. Therefore, when planting edamame, we should focus on applying basal fertilizer and phosphorus and potassium fertilizer to it.

If edamame has smaller leaves, weaker growth, and shorter branches during growth, it means that it lacks fertilizer. In this process, appropriate fertilizers such as urea and boron fertilizer should be applied to the edamame.

<>1. A lot of water is needed during the growth period, especially when the seeds are developing, a lot of water needs to be absorbed, and this period usually needs to be watered every other day, so when the plant reaches the seedling stage, it needs to be watered two or three times a week until the pod-setting stage, the next day.

2. Mao Jingsheng bean (scientific name: glycine max (linn.).) merr.

It is an annual herb of the genus Soybeanaceae in the legume family, 30-90 cm tall. The protein content of soybeans is 35% to 40%. 9] The stems are stout, erect, densely covered with long brown bristles.

Leaves usually have 3 leaflets; The leaves are veined, pubescent with yellow; petioles 2-20 cm long; lobules broadly ovate, papery; racemes short with few flowers, long with many flowers; peduncles usually have 5-8 sessile, tightly packed flowers; bracts lanceolate, coarsely hairy; bracts lanceolate, covered bristles; Sakurayama calyx lanceolate, flowers purple, lilac or white, base with petioles, wing petals castin. pods hypertrophied, slightly curved, drooping, yellowish-green, densely covered with long-brownish-yellow hairs; The seeds are 2-5, oval, nearly spherical, and the seed coat is smooth, with a variety of pale green, yellow, brown and black. The flowering period is from June to July, and the fruiting period is from July to September.

Growing edamame requires phosphorus and potassium fertilizers.

Edamame root system has nitrogen-fixing bacteria, less demand for nitrogen fertilizer, more demand for phosphorus and potassium fertilizer, focus on fertilizer application of basal fertilizer, increase phosphorus and potassium fertilizer, collapse generally per mu with 40-50 kg of compound fertilizer base application or pore, and then in two periods of the source of the skin to see the seedlings to decide whether to apply top dressing. The first is the early growth stage (the stage of growing tall, growing leaves, and branching).

If the leaves are small, the color is light, the seedlings are weak, and the branches are short, and the fertility is insufficient, it is necessary to chase 7-8 kg of urea per mu in time to promote seedling fertilizer; The second is the flowering and podding period, such as the occurrence of pale yellow leaf color, lack of stamina, and symptoms of detachment, 8-10 kg of urea should be applied per mu as flower pod fertilizer. At the same time, when flowering, it is best to spray the foliage with 2-3 taels of borax mixed with water per mu, which is conducive to improving the pod setting rate and increasing the pod weight.

Edamame, commonly known as vegetable soybeans, is a green bean whose harvested grains are not yet ripe, which is rich in nutrients and rich in plant protein, and is known as "plant-based meat". The scientific fertilization techniques of edamame are as follows:

1. Reapply basal fertilizer.

The yield of edamame is high, generally more than 500kg of green pods can be harvested per 667m2, and the high yield can reach 600 700kg. Therefore, edamame requires a large amount of fertilizer during the whole growth period, and requires more potassium fertilizer, so it is very important to reapply basal fertilizer to promote the early growth of edamame, strive for neat seedlings, and robust seedlings. 7 10 days before planting, combined with land preparation, organic fertilizer and inorganic fertilizer are applied at the same time, generally 500 1000kg of decomposed organic fertilizer, 20kg of ammonium bicarbonate, 25kg of calcium, magnesium and phosphorus fertilizer, and 7 8kg of potassium chloride can be applied per 667m2.

In the high-yield cultivation experiment of edamame, the author used a compound fertilizer containing medium and trace elements (mainly mg, mo, b) (n:p2o5:k2o=11:).

5:16) as basal fertilizer, the application rate per 667m2 was 40 50kg, and the effect was significant.

2. Suitable seedling fertilizer.

Edamame is a leguminous plant, and its root system is symbiotic with nitrogen-fixing bacteria, but the root nodules have not yet formed at the seedling stage, and neither nitrogen deficiency nor excessive nitrogen application can be applied at this stage. Nitrogen deficiency will cause abnormal seedling growth, and excessive nitrogen application will affect root nodulation. Therefore, nitrogen application should be appropriate to meet the needs of seedling growth without affecting root nodule formation.

After emergence to before flowering, rhizosphere topdressing can be divided into 2 times, the first time is applied when the first pair of true leaves grow after emergence, generally 6kg of ammonium bicarbonate + 3kg of potassium chloride can be applied per 667m2; or apply compound fertilizer containing medium and trace elements (N:P2O5:K2O=11:

5：16）9kg。The second application in the branching stage, 10kg of ammonium bicarbonate + 4kg of potassium chloride can be applied per 667m2; or compound fertilizer containing medium and trace elements (n:

p2o5:k2o=11：5：

16）15kg。

3. Skillfully apply pod fertilizer.

Edamame needs a lot of potassium, so pod fertilizer should be applied skillfully according to the growth and pod-setting conditions during the pod-setting and grain bulging stage. If the amount of pods is large and the leaf color is light, urea 3 5kg + potassium chloride 5kg can be applied per 667m2; or apply a compound fertilizer containing medium and trace elements (N:P2O5:) per 667 m2

k2o=11：5：16）15―20kg。

If the amount of pods is small, potassium chloride 3 4kg can be applied per 667m2, and when the leaf color is light, urea can be added every 667m2; or apply compound fertilizer containing medium and trace elements per 667 m2 (n:p2o5:k2o=11:

5：16）10―15kg。This fertilization can promote the drum filling of edamame, make the kernels full, and improve the yield and quality.

4. Top dressing outside the roots.

Extra-root topdressing can supplement nutrients for edamame in time and promote the normal growth of edamame. The aqueous solution of ammonium molybdate available at the seedling stage is sprayed 2 times continuously (the interval between the two sprays is 10 to 15 days); Spraying the aqueous borax solution that can be used at the flowering and pod-setting stage can effectively increase the number of pods and promote the increase of yield and income.

Edamame is a common vegetable, and its flowering management is essential for yield and quality. Here are some tips for managing the flowering period of edamame:1

In general, it is suitable for sowing when the temperature is stable at 15-25 degrees Celsius, avoiding hot or cold periods in summer. 2.Suitable soil preparation:

Edamame prefers moist and breathable soil, so it's important to prepare the soil in advance. Before sowing, the soil is loosened and mixed with organic matter to increase soil fertility and retain moisture. Make sure the soil is well drained to avoid the adverse effects of standing water on the plants.

3.Proper irrigation management: Edamame has a high water requirement during flowering, especially in dry weather conditions.

Keep the soil moist, but don't overwater it to avoid root rot. Watering should be evenly distributed to avoid stagnant water and insufficient moisture. 4.

Provide plenty of sunlight: Edamame is a masculine plant and needs plenty of sunlight to promote flowering and pod formation. Make sure the edamame growing area receives enough sunlight and prune the surrounding weeds in a timely manner to reduce competition for light.

5.Proper pest management: During flowering, edamame is susceptible to pests and diseases.

Inspect the plants regularly, pay attention to the detection and timely treatment of the damaged plants. Use organic pesticides or biological control methods to avoid pollution to the environment. 6.

Carry out proper support and pruning: Since edamame plants will grow densely, providing support structures such as bamboo poles or barbed wire can help support the plants and provide good ventilation. Prune unhealthy or overly dense branches in time to promote healthy plant growth.

7.Pay attention to pollination and seed setting: Edamame needs to be pollinated for flowering, which can be aided by gently shaking the plants by wind or artificially. At the same time,

Summary. Hello dear, edamame is in the pre-growth period from sowing to the first flower, and flower buds begin to differentiate 20-30 days before flowering. This period is mainly the vegetative growth stage, and its growth is directly related to flowering, flower pod shedding and yield.

Vegetative growth is robust, the vegetative body is more developed, and the accumulation of sufficient nutrients is the basis for increasing the number of flowers and reducing the shedding of flower pods. The flowering period of edamame is 14-30 days, which is the most vigorous growth period of edamame, and vegetative growth and reproductive growth occur at the same time. In 2 weeks after flowering, the bean grain increases sharply, and the requirements for nutrients and water during this period should not only meet the needs of flowering, but also provide the needs of vegetative growth, such as poor conditions, the number of flowers decreases, and the flowers that have bloomed are easy to fall off.

During the flowering period, the root system of the plant also develops very rapidly, absorbing a large amount of nutrients to meet the needs of plant growth, flowering and poding. Especially after the pod-setting stage, the organic matter produced in the aboveground part is rarely transported to the root system, which must be properly fertilized and watered, so as not to cause premature senescence of the plant, and a large number of flower pods formed in the later stage will fall off, which will seriously reduce the yield.

How much water can be sprayed at the first flowering stage of edamame.

Inhibition of respiration In the early flowering stage of edamame, spray 50 kg of water with 5 grams of sodium bisulfite per mu each time, spray 1 time every 7 days, and spray 2 3 times in a row, which can increase the intensity of photorespiration of edamame and reduce the consumption of photosynthetic products, thereby promoting the accumulation of dry matter and increasing fresh yield. This measure is only applicable to early and medium-ripening varieties and plots with good growth. In the case of drought and hand shortage, it is necessary to water first and then spray.

Spraying should be even, to ensure that all leaves are stained with liquid, such as rain within 12 hours after spraying, after the rain stops, Shenkai sprays.

We belong to the middle and lower reaches of the Yangtze River here, soybeans in the middle of June of the annual solar calendar began to be sown, in the case of good weather, only need to water three times to break the ground and sprout, if it is rainy, do not need to water directly, as long as the soil is moist, but can not be soaked in water, will rot roots and seedlings. These three kinds of pests harm the seedling stage, flowering stage and pod of soybean respectively, and the spider mites at the seedling stage can make the soybean die in patches when it is serious; When the bean insects in the flowering period are serious, they can eat soybeans into bare rods; Insects in the pod can bite the soybean grains and affect the quality of the soybean.

The period is the period when vegetative growth and reproductive growth are the most vigorous, and it is also the period when the dry matter of the plant accumulates rapidly and the leaf area coefficient expands significantly, and the climate of this stage is characterized by high temperature, long sunshine, and large evaporation.

For soybeans, it is an oilseed crop. There are many varieties, and in the system, there are three main categories: soybeans, black beans and kidney beans (green beans). There are also different varieties of various types, so I will not subdivide them here.

Let's talk about the topic! These are harmful to the seedlings, resulting in soybean yield, do a good job, soybean seedlings will grow strongly, to the soybean meeting is not required to play pesticides, but to pick up the soybean seedlings, one is to remove weeds, the other is conducive to ventilation, so that soybean seedlings bloom and hang fruit, which will increase production and income.

There are few pests and diseases that can affect soybeans, but it should be noted that we must be weeded in time, because weeds will rob soybeans of nutrients. The flowering period needs to consume a lot of nutrients, if the flowering period is lacking fertilizer, there will be fewer flower pods, more shedding, light leaf color, weak plants and other phenomena in the middle and late stages of growth. Even if they don't apply fertilizer throughout the growing process, they can grow well, and the yield of one acre of land can reach 300 catties, but since the farmers have already planted, they want to have a higher yield, so they will take some measures to increase the yield.

It is very necessary because only in this way can the growth and development of soybeans be better promoted.
