Cultivation techniques of kidney bean

Kidney beans are called kidney beans in many places. They are popular among bean vegetables. In rural areas, every household will plant a small plot of land. So what is the cultivation technique of kidney bean?

I. cultivation techniques of kidney bean

1. Soil preparation and fertilization

We generally do not plant in wasteland that has not been cultivated for several years, because that kind of soil is full of diseases, pests and germs, so it is not suitable for kidney beans to grow and may not be able to produce pods. When preparing the soil, we try to turn the land over after the last crop harvest, so that some pests can be reduced. during soil preparation, we usually ridge and ditch at a physical distance of 20 to 20. Then evenly sprinkle a layer of livestock dung or dead plants on the ridge, and then you can wait for sowing.

2. Sowing and raising seedlings

The seed coat of kidney beans is relatively hard, so when sowing directly, the budding speed is very slow, so we will first put the seeds in the sun for two or three days, and then soak the seeds in formalin solution for more than ten minutes. then take it out and rinse the medicine with clean water, then dry it and sow it. There are three ways of sowing, the first is strip sowing, that is, sowing seeds row by row on a good ridge, the second is hole sowing, burrowing seeds in the ridges at a distance of 30 centimeters per plant, and the third is transplanting. First, the kidney bean seeds are cultivated on the seedling bed, and then transplanted to the whole field when it grows to about 10 centimeters.

3. Temperature management

Kidney beans have strict requirements on temperature. for one thing, their cold resistance is very poor, and secondly, they will stop growing under high temperature conditions, so we should pay special attention to temperature control when planting kidney beans when they are hungry. In Hunan, we usually plant kidney beans in March and April in spring, and then produce kidney beans around June. During this period, the temperature is basically stable at 15 to 28 degrees, so the temperature is neither hot nor cold. On the other hand, kidney beans will stop growing when the temperature is lower than 10 degrees and burn to death in an environment higher than 30 degrees, so we try our best to plant them according to the seasonal changes of the region, and we can also use greenhouse technology to grow them. In this way, the management of the temperature is relatively simple.

4. Fertilizer and water management

The fertilizer and water needed for the whole growing period of kidney beans are as follows. Under normal circumstances, kidney beans need to be watered and fertilized for the first time after planting, so that the growth of kidney bean seedlings in the field is not like up and down. We usually wet human feces and urine, and then put 50 jin of urea in the middle. The second fertilization is when kidney beans climb seedlings, which requires a lot of nutrients, but it should also be reasonably controlled to prevent the phenomenon of growing seedlings without blossoming and bearing beans. On average, 30 jin of urea, 20 jin of phosphate fertilizer and 20 jin of potash fertilizer per mu are mixed and sown. The third fertilization is when kidney beans blossom and bear beans, we can promote the flowering period, but also increase the bean setting rate. This fertilization can add 30 jin of boron fertilizer on the basis of the second fertilization.

5. scaffolding management

In order to increase the yield of kidney beans, we usually build some shelves or sheds when the kidney bean seedlings grow to about 30 centimeters, connect them to each frame with ropes, and then pull the kidney bean seedlings to the frame. Let them crawl along the rope to grow, so that the yield will be much higher than it crawls on the ground, and avoid a lot of diseases and insect pests. So it is very necessary to set up a frame to deal with it.

6. Disease control

Kidney bean diseases are relatively rare, and the most common diseases may be leaf blight and root rot. Growers in general know how to prevent these two diseases. After all, it is a common disease of all crops. First of all, we have to prevent two kinds of diseases is to do a good job in field management, and then we can use carbendazim solvent to prevent and cure the disease. The most important thing is to prevent pests, the most important are master insects, aphids, inchworms and vegetable insects, and the most effective control method is to spray trichlorfon or Bordeaux solvent on bean seedlings.
