Analysis of the Causes of Premature Senescence in Winter Melon and Preventive Measures

Premature senescence in winter melon means that the plant's growing vigor can no longer normally support it through its full life cycle; in most cases, the plant's vigor becomes low or the plant dies before the fruit ripens. Winter melon grows quickly when setting fruit in the later stage, but if it is not managed properly, premature senescence can occur, affecting yield and quality and causing serious economic losses for farmers. So what exactly causes premature senescence? And how can it be prevented? Let's take a look together with Qinnong.com.

1. Low fruiting node position

After winter melon flowers and sets fruit, because the plant is short and growing poorly, the individual plant is smaller and its growth is weak; in particular, the leaf area is small, so the nutrients synthesized through photosynthesis are relatively few, which can no longer meet the needs of plant growth and flowering and fruit setting, thus causing premature senescence.

Preventive measures: For this situation, when choosing what to plant, select excellent varieties with robust growth; then when choosing soil, it is advisable to choose deep, loose and fertile soil, strengthen fertilizer and water management, and increase the nutrients needed for plant growth. Especially when the plant is growing weakly, in order to avoid premature senescence, some flowers or young fruit can be appropriately removed to reduce nutrient consumption.

2. Insufficient basal fertilizer application

During the growth of winter melon, the demand for fertility is relatively high, especially for basal fertilizer. If the basal fertilizer is insufficient and no timely topdressing is done later, the supply of nutrient elements will be insufficient, and the plant will show premature senescence.

Preventive measures: When sufficient basal fertilizer has been applied, topdressing should be done promptly according to the plant's growth condition and fertilizer requirement, so as to supply sufficient nutrients and avoid premature senescence. At the same time, in the later stage, if the plant shows signs of premature senescence, foliar spraying and root topdressing can be carried out at the same time.

3. Soil problems

Winter melon has relatively strong adaptability to soil, but some farmers, in order to implement crop rotation or avoid other crops, are rather careless when choosing land and plant in plots with heavy soil viscosity and poor fertility. With insufficient fertilization and no timely loosening of the soil or weeding, the plants are left to fend for themselves, resulting in fertilizer deficiency and premature senescence.

Preventive measures: Winter melon has relatively strong adaptability to soil and can be planted in ordinary soil. As long as the soil is not too barren or too high in acidity or alkalinity, it can generally grow and set fruit normally. After planting, management should be done frequently.

4. Improper watering

During the growth and fruiting period of winter melon, the demand for water is extremely large. If watering is too little at this time, the plant cannot meet the water needs for fruit setting and will show premature senescence. However, during growth, if watering is excessive, too much water accumulates in the soil, affecting soil permeability; root growth is hindered, and normal respiration and absorption cannot occur, causing the plant to gradually wither and show premature senescence.

Preventive measures: When watering, follow the plant's growth state. In dry seasons, water promptly to keep the soil moist, while in rainy seasons, drain promptly to prevent waterlogging and root rot.
