How to grow kidney beans for high yield

Kidney beans are also called kidney beans in many places. They are a kind of vegetables that are more popular among the public. In rural areas, every household will plant a small piece of land. Now there are many people in the city who will plant one or two plants on the balcony and eat several meals. Therefore, planting is also very simple. So today, the pro-agricultural network wants to teach you about the high-yield planting method of kidney beans. Let's learn about it together.

1. Soil preparation and fertilization

We generally do not plant in wasteland that has not been cultivated for several years, because there are many pests and diseases in that soil, which is not suitable for kidney bean cultivation and is likely to fail to produce pods. When we prepare the soil, we try our best to turn over the land after the last round of crop harvest, so as to reduce some pests. When preparing the soil, we usually make ridges according to the physical distance of 20 to 20, and then evenly spread a layer of livestock manure or withered wood on the ridges, and then we can wait for sowing.

2. Sowing seedlings

The seed coat of kidney beans is relatively hard, so the germination speed is very slow, so we will first put the seeds in the sun for two or three days, then soak the seeds in formalin solution for ten minutes, then take them out and wash them with clean water, and then dry them before sowing. There are three ways of sowing. The first is drilling, that is, sowing seeds in rows on a good ridge. The second is hole sowing, planting holes on the ridge according to the distance of 30 cm for each plant. The third is transplanting. First, the kidney bean seeds are cultivated on the seedbed. When it grows to about 10 cm, it is transplanted to the whole field.

3. Temperature management

Kidney beans have strict requirements for temperature. First, their cold resistance is extremely poor. Secondly, they will stop growing under high temperature conditions. Therefore, special attention should be paid to the regulation of temperature when planting kidney beans. In Hunan, we usually plant kidney beans in March and April in spring. Then, kidney beans will be produced in June. The temperature of this section of gold is basically stable at 15 to 28 degrees Celsius, so the temperature is neither hot nor cold. The kidney beans will stop growing at temperatures below ten degrees and burn to death in environments above thirty degrees, so we try our best to plant them according to seasonal changes in the area, and we can also use greenhouse technology to plant them.

4. Fertilizer and water management

The fertilizer and water required for the whole growth period of kidney beans are as follows. Under normal circumstances, kidney beans need to be watered and fertilized for the first time after planting. At this time, in order to make the growth of kidney bean seedlings in the field different from up and down, we usually irrigate human excrement and urine, and then add 50 jin of urea in the middle. The second fertilization is when kidney beans climb seedlings, at this time a lot of nutrients are needed, but reasonable control is also needed to prevent the phenomenon of excessive seedling growth without flowering and bean bearing. On average, 30 catties of urea, 20 catties of phosphate fertilizer and 20 catties of potassium fertilizer are mixed and broadcast per mu. The third fertilization is when the kidney beans bloom and bear beans. We can promote the flowering period and also improve the bean setting rate. This time, we can apply 30 jin of boron fertilizer on the basis of the second fertilization.

5, erection management

In order to improve the yield of kidney beans, we generally set up some shelves or sheds when the kidney bean seedlings grow to about 30 cm, connect them to each shelf with ropes, and then pull the kidney bean seedlings to the shelves by plants, let them crawl along the ropes along the shelves, so that the yield will be much higher than it crawling on the ground, and at the same time avoid the occurrence of many diseases and insect pests, so the shelf treatment is very necessary.

6. Disease control

Kidney bean diseases are relatively few, the most common may be dead leaf disease and root rot, for these two diseases in general farmers know how to prevent, after all, it is a common disease of all crops. First of all, we can prevent two diseases by doing field management well, and then when the disease occurs, we can control it with multi-agent solvent. The most important thing is to prevent pests, the most important is the army insects, aphids, geometrids and vegetable insects, etc., the most effective control method is to spray trichlorfon solvent on bean seedlings, or Bordeaux solvent.
