Brue beans, also known as beans or seasonal beans in some places, is the most common rural planting, one of the most common vegetable crops on the market. Kidney beans are a very nutritious crop, rich in protein, fat, carbohydrates, dietary fiber, vitamin A, radicin, thiamin, riboflavin, niacin, vitamin C, vitamin E, calcium, phosphorus, sodium and other nutrients, but also a high potassium, high magnesium, low sodium agricultural products, is more suitable for low blood potassium, high blood fat, heart disease, arteriosclerosis and other conditions of the person to eat. Then today let us take a look at the spring greenhouse kidney bean management is very important, spring greenhouse kidney bean management to pay attention to what?

1. timely pinching

The greenhouse kidney beans and open field kidney bean cultivation environmental conditions are different, due to the high temperature in the shed performance growth rate, easy to appear plant type pods less phenomenon. In order to improve the yield of greenhouse kidney beans, take the method of pinching, can regulate the reasonable layout of the upper and lower branches of kidney beans. It has been observed that greenhouse kidney beans from the third group of leaves formed, the internode obviously lengthened, trailing growth speed accelerated, according to this point to determine the timing of the timely pinch. From the third group of leaves after the start of the shape of the pinch, can control the main vine of prolongation, promote the lower lateral branch sprouting. On the contrary, if the pinch node is too high, the vigorous growth of the main vine can not be controlled, and the lateral branch sprouting is also very slow, the lateral branches do not need to be pinched after the emergence of the pinch. But to the top of the 20 cm height from the surface of the greenhouse should be pinched in a timely manner, to prevent the upper branches and leaves flourish to affect the light.

2. Cultivate strong seedlings

Brasset beans winter and spring crop cultivation, the entire reproductive cycle through the fall, winter and spring three seasons. The climate of the whole process is characterized by high temperature to low temperature and back to high temperature. The key to high yield of winter and spring kidney beans is to master the plant growth in the low temperature period before the completion of nutritive growth, in the low-temperature period of slow flowering, pods of reproductive growth, early spring when the outside world temperature rebound when the product can be a large number of marketed to obtain a higher yield and economic benefits. The early and late sowing period is related to the total yield. It has been observed that the early sowing period, early nutrient growth rate, early into the pod season, when the low temperature and low light, due to the nutritional supply and demand contradiction is large, it is easy to cause plant aging, reduce yield. Sowing late, the arrival of low temperatures, nutrient growth has not been completed, although it reduces the amount of plant nutrient growth, early flowering and fruiting, but it is easy to form a small old seedlings, early spring light, the temperature is appropriate, but also can not reach the expected pods bloom. All over the winter and spring stubble kidney bean cultivation sowing period, according to the development of seedling, seedling and early flowering growth time takes 50 ~ 60 days, most areas of China generally the lowest temperature in January, therefore, in mid-October sowing is more appropriate.

3. The land for bed sowing

Planting of spring rack kidney beans is best used in the winter, before the winter to be deep turning. Although the rhizobacteria within the root tumors of the kidney bean can fix some of the nitrogen, however, to get a good yield, it is still necessary to apply nitrogen fertilizer. At the same time, kidney beans sensitive to the response of phosphorus and potassium fertilizer, increase the application of phosphorus fertilizer can promote the activity of rhizobia, play the role of phosphorus to increase nitrogen. According to analysis, kidney bean flowering period of phosphorus, potassium absorption is more than the amount of nitrogen absorption. Therefore, in the cultivation of kidney beans, adequate basal fertilizer, especially the application of phosphorus and potassium fertilizer, is an important condition for the productivity of kidney beans. Base fertilizer combined with the pre-sowing ground turning into. After the ground is rectified, made into a 1.2-meter wide flat bed.
