How to grow beans with high yield

Selection of varieties: the widely cultivated variety is cowpea 28-2. Sowing method: the temperature can be stabilized at 4 ℃ before and after breaking frost, 2-4 seeds per hole and 2-3kg sowing rate. Field management: after the main vine climbs to the top of the frame, it is necessary to hit the top of the main vine in time, which is conducive to the growth of lateral vines. Control of diseases and insect pests: use 25% insecticidal double water agent 500x solution, 60kg with water, spray once every 7-10 days from budding to early flowering, and spray 2-3 times in a row.

I. selection of varieties

Select high-quality grain full varieties, you can first try a few soaking to promote sprouting, and then observe the soil breaking rate before sowing, beans are very many, some people like beans flat and small, some people like those suitable for sour beans, but in fact, more people like white-blue beans, because the meat is thick, beans are full, generally widely planted varieties are cowpeas 28-2 cowpeas, suitable for spring plastic film mulching.

2. Sowing method

The suitable lower limit temperature of sowing bean is 14 ℃. Generally, the sowing method of bean is the same as kidney bean when the temperature is stable at 4 ℃ before and after frosting. The suitable row spacing is 65cm, hole spacing is 18-25cm, sowing holes per mu is 4000-5000 holes, sowing 2-4 seeds per hole, sowing amount is 2-3kg.

III. Field management

In the later stage, it is necessary to erase the lateral buds below the first inflorescence, as well as the flower buds and leaf buds above the inflorescence, and plant the leaf buds in the mixed buds at the same time, then top the middle and upper lateral branches after seeing the flower buds, and pay attention to the need to hit the top of the main vine after climbing to the top of the frame, which is beneficial to the growth of lateral vines, and the lateral vines still top after seeing the flower buds.

IV. Prevention and control of diseases and insect pests

1. There are many diseases and insect pests in beans. Generally speaking, the first whole-seedling insecticidal spray can be carried out before blooming, and then a whole-seedling insecticidal spray can be carried out when the beans grow out, so that when the beans grow again, there will not be so many insect pests, and there is no need to worry about pesticide residues.

2. The main pests that are easy to occur are bean pod borer and cowpea pod borer. 60kg can be sprayed once every 7-10 days from budding to early flowering, and it can be sprayed 2-3 times successively. In the middle and later stages of bean growth, you can also spread a layer of lime powder on the surface, and then sprinkle a layer of lime powder on the seedling rack, which is beneficial to insect control.

5. Timely harvest

1. After the pod is long enough, it needs to be harvested in time. If the harvest is delayed, it will lead to seed expansion, easy to reduce the commodity quality, and also affect the pod growth in the later stage. When harvesting, be careful not to hurt other inflorescences, flower buds, vine leaves, cowpea tender pods and seeds taste very delicious, edible methods are more, can be fried, stewed, boiled, mixed, stuffing and so on.

2. Tender pods can be fried or cold, and can also be used for processing quick-frozen, dried, pickled, fresh vegetables, canned vegetables, etc., which is an excellent raw material for processing export to earn foreign exchange. There are many varieties of cowpeas that are generally eaten, which are mainly divided into green cowpea, flower cowpea, white cowpea, red cowpea, etc., and the dried seeds of beans can also be used for cooking, porridge, powder and sauce.
