The benefit of premature delivery of kidney beans after picking leaves first is high.

After picking a batch of fruits, kidney beans take a long time to germinate, and kidney beans in winter and spring mostly have to be listed at a higher price before and after the Spring Festival, so try to make them bear more fruit and go on the market early at this stage. is what many kinds of kidney bean farmers want to do. Master Zhang Kecai, Dongxia Town, Qingzhou City, increased kidney bean production by picking leaves first and then picking hearts, and went on the market just before the Spring Festival. First of all, pick the leaves. After picking a batch of fruits, kidney beans first remove the superfluous old leaves and yellow leaves in the lower part, and then remove the middle one of the three leaflets on each petiole of kidney beans, in order to reduce nutritional consumption and make the plant concentrate nutrients to promote lateral bud germination. the amount of leaves picked depends on the situation of the plant, and the branches and leaves are picked more in the shade, otherwise less, generally not more than 1/3 of the total leaves of the plant. Strengthen fertilizer and water management after picking leaves, 20 kg compound fertilizer can be applied with water per mu, and combined with conventional fertilizer and water management, 0.2% urea mixed with 0.3% potassium dihydrogen phosphate and other foliar fertilizers are sprayed to promote lateral bud germination ahead of time. Secondly, pick the heart. In general, kidney beans can be erased after the first spike flowers, the main vine climbed to the top of the frame to pick the heart, the later side branches should also pick the heart after sitting pods. The coring of the main vine promotes the growth of lateral branches, while the wiping of branches and the coring of lateral branches promote the growth of pods. In addition, picking the heart also has the function of controlling prosperity and growth. Kidney bean root has deep drought tolerance and exuberant growth, which is more prone to the phenomenon of excessive vegetative growth than other vegetables. when cultivated in the greenhouse with weak light, high temperature and sufficient fertility, vigorous vegetative growth is more common, which will affect flowering and pod formation. Therefore, for prosperous plants, it is a good way to pick the heart in time, in addition to temperature and drug control. Although the method of picking leaves and then hearts of kidney beans is only a small improvement, it has made Master Zhang's kidney beans more than ten days ahead of schedule, and the output has also been greatly increased. Compared with the same period in previous years, the output has increased by more than 300 jin, and up to now it has sold more than 1,000 yuan.
