Problems and Prevention Measures of Watermelon Blossoming

First, there is a problem
1, plant leggy: Extend vines to flowering fruiting period of excessive nitrogen fertilizer, field humidity, vegetative growth and reproductive growth do not coordinate, causing leggy.
2, vine leaf weakness: due to watermelon flowering set fruit period encounter drought, defertilization, plant malnutrition, fertilizer and water shortages and other reasons, resulting in thin plants, thin leaves, ovary thin, the whole plant is not premature aging.
3, do not set fruit: watermelon flowering set fruit fruiting phenomenon. Appearance: water over watermelon fertilizer, so that the plant nutrition disorders, stems and leaves lengthy, resulting in falling flower or melon; plant growth is thin, ovary thin or poor development will reduce the rate of sitting; spraying insecticide, especially spray Chrysanthemum pesticides, killing pests also reduce the number of pollinating insect populations, affect insect pollination, reduce the rate of cucumbers sitting; watermelon flowering period encounter bad weather, low temperature and high humidity affect watermelon fruit set.
Second, prevention and control measures
1. Reasonable fertilization and irrigation: The principle of “pre-promoting, central control, and post-loading” is applied for fertilization. Schiff base fertilizer, after planting a small amount of nitrogen fertilizer to promote vine extension, extend the vine period to the flowering period to control fertilizer control water, set fruit after re-fertilizer water. Some foliar fertilizers can be sprayed later.
2. During the flowering period, when it encounters low temperature and rainy weather, artificial pollination is needed. Artificial pollination can also be conducted with pollen that is resistant to low-temperature and early-maturing varieties.
3, scientific pruning and melon: improve the pruning technology, according to the planting density reasonable selection side vine. Generally 2 to 3 vines, more sideways vines increase the number of female flowers, there is room for selective pollination. It can also strengthen pruning and control leggy.
4. Pay attention to the selection of appropriate pharmaceutical agents when controlling pests during flowering.
