How to fertilize green beans

Green beans is a very common dish in daily life, whether stir-fried or dry pot taste is very good, the content of nutrients is also very high, in many families is a favorite dish of men and women, young and old, although the output of green beans on the market has been very large, but still very popular, and the price is much more expensive than some other vegetables So today, the pro-agricultural network is going to teach you how to fertilize the beans.

1. Base fertilizer

We need to choose the basic fertilizer application of kidney beans according to the fertility of the planting land and the varieties of green beans to be planted. If the soil is more fertile, then we only need to apply 4,000 kilograms of organic fertilizer or farm rotten fertilizer per mu, but if it is poor, we need to increase the amount of fertilizer application by at least 1,000 kilograms. Green beans with higher seedlings also use more fertilizer, so we apply about 100 kilograms of plant ash or about 50 kilograms of phosphate fertilizer on the basis of 5,000 kilograms, while green beans with short seedlings do not need it.

2. Seedling fertilizer

Seedling fertilizer is generally released about seven to ten days after emergence and planting, because the four seasons bean seedlings have basically survived at this time, and it is best to apply them as far as possible when the four season bean seedlings are about 15 to 20 centimeters, because the basic fertilizer in the early stage can also make the seedlings grow rapidly, while the nutrients in the later stage will become thinner and thinner, and topdressing is the wisest choice at that time. The seedlings of many crops are fertilized with nitrogen fertilizer, but the seedling fertilizer of kidney beans is mainly based on phosphate fertilizer, and an appropriate amount of about 25 jin of nitrogen fertilizer can be added, because too much nitrogen fertilizer will cause the seedlings of string beans to grow without pods.

3. Flower fertilizer

The flowering period of kidney beans also needs a lot of nutrients, and the nutrient supply of the flowering period is also a critical period, because the number of flowers also determines the yield of green beans to a certain extent. so during this period, we are mainly fertilizing, with an average of about 30 jin per mu, and then an appropriate amount of urea can be applied to prevent the aging of kidney bean seedlings. At the same time, it can prolong the flowering period and increase the pod setting rate.

4. Pod fertilizer

Pod fertilizer is about a week after the flower fades, when the green beans have slowly appeared a small outline, in order to make the green beans grow fuller and have no deformity, so we need to spray some foliar fertilizer appropriately. It is mainly boron fertilizer, about 35 jin per mu of boron fertilizer, followed by proper watering of some phosphate and potash fertilizer, which can promote the growth rate of pods and improve the quality of kidney beans.

5. Curing fertilizer

Since kidney beans are harvested in batches, conservation fertilizer is also important to improve the yield of green beans. Generally, they need to be released after harvest, mainly with fecal and urine water. About 10 jin of urea can be mixed evenly in the middle and released, which can prevent the seedlings from aging to a certain extent, resulting in a reduction in production. At the same time, it can promote the growth of new branches and leaves, accelerate ripening and promote flowering.
