The planting method of kidney bean

Soil preparation and fertilization: after soil consolidation, ridges and ditches are made according to the distance of 20cm, and a small amount of livestock manure or dead plants are scattered in the ditches. Sowing and raising seedlings: the seeds need to be exposed to the sun for 2-3 days, and then soaked and disinfected before sowing. Strip sowing, hole sowing, transplanting and other methods can be used. Temperature: the cold resistance is poor, and the suitable temperature for growth is about 15-28 ℃. Fertilizer and water: watering and fertilization should be carried out after planting, and topdressing twice in the later stage. Scaffolding: kidney bean seedlings grow to 30cm when scaffolding.

1. Soil preparation and fertilization

1. Kidney beans are not suitable for planting in wasteland that has not been cultivated for several years. Because there are many germs and insect pests in this soil, it is very likely that kidney beans cannot produce pods, so during soil preparation, after the last round of crop harvest, the soil will be turned over, which can reduce the occurrence of some diseases and insect pests.

2. During soil preparation, ridging and ditching can be done according to the distance around 20cm, and then evenly sprinkle a small amount of withered grass or livestock manure on the ridge, and then wait for sowing.

2. Sowing and raising seedlings

1. Because the seed coat of kidney bean is relatively hard, if sowing directly will lead to slow sprouting, so you can first put the seeds in the sun for 2-3 days, and then soak the seeds in formalin solution for about 10 minutes. rinse it out with clean water, dry and wait for sowing.

2. There are three ways of sowing, the first is strip sowing, which is to sow the seeds row by row on the ridge, the second is hole sowing, which can be planted in the ridge according to the distance of each 30cm, and the third is transplanting, which can be cultivated on the seedling bed, and then transplanted to the field when it grows to about 10cm.

III. Temperature management

1. Kidney beans have high requirements for temperature, and their cold resistance is relatively poor, so they will stop growing in high temperature environment, so we should pay attention to temperature control when planting kidney beans. In Hunan, we can choose to plant kidney beans from March to April in spring. Then kidney beans will bear fruit around June.

2. During this period, the temperature needs to be stabilized at about 15-28 ℃, and kidney beans will stop growing when the temperature is lower than 10 ℃, and the plants will burn to death when the temperature is higher than 30 ℃, so they need to be planted according to the seasonal changes of the region, and can also be planted in a greenhouse, so it is relatively simple to manage the temperature.

IV. Fertilizer and water management

1. Kidney beans need to be watered and fertilized once after planting. In order to ensure the neat growth of kidney bean seedlings in the field, you can generally choose to pour manure and urine water, and then mix 50 jin of urea in the middle.

2. In the second fertilization, when kidney bean is climbing seedlings, 20 jin of phosphate fertilizer, 20 jin of potash fertilizer and 30 jin of urea can be mixed per mu.

3. The third fertilization can promote the flowering period and increase the bean setting rate when kidney bean blossoms and sets beans. 20 jin of phosphate fertilizer, 20 jin of potash fertilizer, 30 jin of urea and 30 jin of boron fertilizer can be mixed per mu.

Fifth, erection management

You can choose to build a shelf or shed when the kidney bean seedlings grow to about 30cm, connect them with ropes, and then pull the kidney bean seedlings to the frame to let them crawl and grow naturally, which is much higher than crawling and growing on the ground, and can also reduce the occurrence of diseases and insect pests.

VI. Prevention and control of diseases and insect pests

The common diseases of kidney bean are leaf blight and root rot. To prevent these two diseases, we should first do a good job in field management, and then spray carbendazim solvent to control them. Kidney bean common pests are aphids, inchworms, vegetable insects, army insects and so on. A more effective control method is to spray trichlorfon solvent, or Bordeaux solvent for control.
