Techniques of Cultivation and Management of Kidney Beans in Overwintering Stubble in Greenhouse

After the planting of the green beans in the greenhouse to the end of the harvest, it will go through three growth stages: 10-15 days of the tree planting period (including 8-10 days of slow seedling stage); 15-30 days of the vine throwing period; 60-150 days of successive flowering The pod setting period is the longest overwintering kidney bean in the solar greenhouse, and includes the flowering and flowering pod setting periods of new shoots growing in the middle and lower parts of the plant in the later period.

The first two growth stages mentioned above were based on vegetative growth. The rooting and rooting of the plant, the extension of the branch, the increase of the number of compound leaves and the increase of the leaf area, in order to set up a good plant yield frame, while continuing to start from the seedling stage Flower bud differentiation, the trend of flower bud differentiation is getting stronger and stronger, and more and more flower buds are differentiated, so that the reproductive growth is gradually strengthened until it reaches the early stage of flowering.

The main directions of cultivation management in these two growth stages are: preventing plants from becoming long, promoting stable growth, growth and differentiation of flower buds, making flower buds more and flower buds strong, which is good for reducing buds, flowers and young pods, and improving the rate of pod formation basis.

The latter stage of growth is the vigorous growth of both vegetative and reproductive plants, and gradually transitions to reproductive growth. That is, while growing stems and leaves, and at the same time showing buds, flowering, and pod formation, it is related to the rate of pod formation, how many pods per plant determine the stage of yield.

The main direction of cultivation management is to reduce "three drops" (ie, drop buds, drop flowers, drop young pods) and increase the rate of pod formation. According to the survey, the ability of diffusing kidney bean to differentiate flower buds is extremely strong, each plant can differentiate 15-25 inflorescences, each inflorescence bears more than 20 buds, and only the unshed buds have 5-11 flowers and pods 0- 3, the number of pods accounted for 9% of the number of buds, about 15% of the number of flowering. Therefore, the main direction of reducing "three drops" and increasing the rate of pod formation is correct.

In order to prevent the growth of weeds in sheds, some vegetable farmers have covered black beans with black plastic film. This is an unscientific practice. Because the ground temperature required for kidney bean growth and development is always about 3 ℃ higher than the required temperature. After the black mulch is covered, the ground temperature is lower than the indoor temperature due to the blocking of the sun, and the black mulch has no backlight, which is not conducive to the growth and development of kidney beans. Therefore, it is recommended that friends of vegetable farmers not cover black beans with black plastic film.
