Premature senescence of winter melon plants means that the viability of winter melon plants is insufficient to support the normal life cycle of melons, and most of them reduce their vitality when the fruits are not ripe. The growth of winter melon in the middle and late stages is very large, and the growth rate is extremely fast. Improper cultivation and management is prone to premature aging, which affects the yield and quality of winter melon. The following is a brief introduction to the causes and prevention methods of winter melon premature aging, for your reference.
1, the cause
The main reasons for this are as follows: 1 The fruit setting is low. After the first female flower of Huadong melon is flowering and fruit setting, due to insufficient plant growth, the individual is small, especially the leaf area is small, and the photosynthesis produces less nutrients, which can not meet the large nutrients needed for vegetative growth and reproductive growth of the plant, so that the plant is prone to premature aging. . 2 insufficient application of base fertilizer. The amount of base fertilizer needed for winter melon cultivation is relatively large. If the application of base fertilizer is insufficient and can not be supplemented in time, the melon will prematurely decay. 3 soil texture reasons. Many producers believe that winter melon has strong adaptability to the soil. At the same time, in order to avoid competing with other crops, the melon is planted in a barren soil, and the amount of fertilizer is insufficient, and the plant is more prone to premature aging. 4 soil moisture status is not suitable. Excessive or insufficient soil moisture can also cause premature aging of plants.
2, prevention methods
Prevent the early decay of melon early detection and early resolution. Mainly solved from the following aspects:
2.1 Promote the development of roots. It is advisable to choose sandy loam or loam where the soil is deep and the soil is fertile. In order to improve soil permeability and improve soil fertility, it is necessary to apply high-quality decomposed organic fertilizer of 37,500 kg/hm2, chicken manure to account for 60%, and the rest for pig manure or cow dung.
2.2 Reasonably pruning melons. Reasonable pruning and proper sectioning of melons are the main measures. Winter melon is generally dominated by the main vine, and timely removal of the side vine can promote the growth of sitting melon and melon. Small winter melons see the female flowers and leave melons, leaving 2 to 4 per plant. The large winter melon is suitable for the second and third female flower nodes, leaving only one melon per plant.
2.3 Timely topdressing. Insufficient supply of nutrient elements is one of the main causes of premature aging of plants. According to the growth of melons, timely application of fertilizers in the case of fertilizer needs during the winter melon growth period can prevent premature aging. In order to quickly exert the fertilizer effect, foliar spray fertilizer and root topdressing can be carried out simultaneously.
