Plant leggy â— Excessive application of nitrogenous fertilizer in the period of vine extension to flowering and sitting period, high humidity in the field, incoordination of vegetative growth and reproductive growth, and long madness. Vine leaf weakness â— The performance of the plant is thin, the leaves are thin, the ovary is spherical, thin, and the whole plant is premature. The main reason is that during flowering and fruit setting period, drought, defertilization, plant malnutrition, and severe shortage of fertilizer and water are encountered. No fruit The performance of flowering fruiting period appeared fruiting phenomenon. The reasons for this are: â— Over-fertilizer during flowering, plant malnutrition, and stems and leaves appear to grow long, resulting in falling flowers or melons, reducing the rate of sitting. â— Thin plant growth, thin or poor ovary also reduce the rate of sitting. â— Insecticides are sprayed during flowering, persecuting insects visiting flowers, and reducing the rate of squashing. â— In case of adverse weather conditions during flowering, if the temperature is too high or too low, it will affect fertilization, resulting in a decrease in the rate of culturing; heavy rain during flowering, which causes flowering, or mud splashing from rain, will pollute the flowering period, resulting in falling flowers or melons. Overcoming measures 1 According to different varieties, determine the appropriate sowing date and cultivate strong seedlings. 2 Reasonable fertilization and water management. Fertilization is based on the principle of “promoting, controlling, and accumulatingâ€. Moisture is based on the needs of different physiological stages, pumping vines to flowering period to ensure adequate moisture, expansion of water supply during the expansion period, appropriate control of water during maturity. Fermentation requires fertilizer in the critical period, foliar spray 0.2% P and K source solution, can play a role in improving nutrition, improve fruit and so on. 3 artificial pollination. When the flowering season is cold, the male and female flowers are bagged for artificial pollination. It is also possible to artificially assist pollination by means of pollen which is resistant to low-temperature early maturing varieties. 4 Scientific pruning leaves melons. Watermelon generally uses double or triple vine pruning. Double vine pruning is chosen to stay outside the main vine, and a robust side vine is selected at the base of the main vine, and all other side vines are removed. When the young fruit grows to the size of the steamed bread, the fruit begins to expand rapidly. In this case, the fruit no longer falls. Therefore, it is necessary to timely select the fruits with good nodes and fruit shape, and the double-vine or triple-vine pruning leaves one fruit per plant. 5 Reduce spray time during flowering to avoid accidental injury to insects or phytotoxicity.
