It is not wrong to skillfully manage the seed and fruit of towel gourd in the later period.

Most vegetable farmers retain their own towel gourd seeds in the late stage of towel gourd. Generally speaking, the plant after leaving the seed will no longer carry on the normal production of towel gourd. However, it takes 80 to 90 days from towel gourd sitting to seed maturation, and only cultivating seeds in these nearly 3 months is bound to affect the efficiency of towel gourd production. If the towel gourd is skillfully managed in the later period, it can ensure that the towel gourd will not be mistaken. When towel gourd enters the planned seed retention period, keep a side vine in advance at the lower 1-2 nodes of the planned seeds. After the main vine is peeled, the side vine will continue to bear melon instead of the main vine. At least 5 or 6 leaves should be retained above the melon strips of the main vine to ensure the nutrition needed for seed development. The lateral vine should be suspended in time, and it is not appropriate to keep the melon 15 days after the main vine is planted, so as to prevent the competition for nutrition from affecting the normal development of the seed. Because about 15 days towel gourd strip expansion basically ended, into the seed maturity, so in order to avoid planting melon too small or slow expansion, it is not appropriate to leave melon on the side vine. At the same time, the nutrition produced by lateral vine leaves can also supply the growth of melon, which is convenient to improve the quantity and quality of seeds cultivated. In the early stage of lateral vine melon, the anther concentration should be small. Formula: in 2 kg of water, add 10ml liangguosin, 6ml 2Magne4Lindl D, 10ml naphthalene acetic acid, 10ml Hualaibao, 12ml towel gourd anthocyanin, 20ml green source, 1g rotting spirit, sit Guoling can not be added first, in order to reduce the competition for nutrition, avoid hormone poisoning, and cause plant premature senescence. After 80 days and 90 days, the concentration of anther can be increased appropriately after planting melons. The concentration of the anther can be increased to 8 milliliters, and then 10 milliliters of zhiguoling can be added. Although the root system of towel gourd is well developed, after entering the seed retention period, towel gourd has entered the later stage of production, and the plant inevitably has a decline phenomenon, so in order to ensure that there is no mistake between seed retention and gourd, it is necessary to increase the amount of fertilizer. Topdressing can be done by flushing and foliar spraying. It can be combined with the application of biological bacterial fertilizer and high potassium chemical fertilizer to achieve the purpose of promoting roots and trees, protecting flowers and fruits. Biological bacterial fertilizer and high potassium fertilizer were 20 and 25 kg per mu and 15 kg and 20 kg per mu respectively. Potassium sulfate compound fertilizer can also be applied with 25kg / mu each time. Foliar fertilizer spraying is mainly to supplement the deficiency of rhizosphere topdressing, in order to meet the nutrition needs of towel gourd seeds and melon, and can be sprayed with fully nutritious foliar fertilizer.
