Luffa melon management technology
Keeping the shelving's good permeability Loofah is most afraid of hot weather, and can easily cause melons under high temperature. After the beginning of autumn, the temperature dropped significantly, which is conducive to the rapid growth of melon vines and melon strips. This period is the period of vegetative and reproductive growth. Therefore, we must support the scaffolding to maximize the space for the extension of the vines, keep the melon vines from overlapping, and increase the permeability of the scaffolds. This will facilitate the differentiation of female flowers, increase the rate of the segregation, and preserve the appearance of melons. .
Second, scientific management
After the fertilizer water enters the guava period, the requirements for water and fertilizer are high. Usually 3-4 days watering once, it is better to water in the morning and evening. Combining watering and chase with melon fertilizer, the cooked peanut cakes and bean cakes (deep furrows) can be applied and ternary compound fertilizers such as urea, phosphate fertilizer and potassium sulfate can be added. The amount of topdressing depends on the growth of the plant and the use of basal fertilizer. It is necessary to master the principle of “drinking less and eating moreâ€.
Third, removal of male flowers and tendrils
Loofah is a cross-pollinated crop, because the male flower inflorescence is longer, about 30-40 days, which is equivalent to 3-4 times of the female flower's result period, and consumes a lot of nutrients during this period. Therefore, removing unnecessary male inflorescences as soon as possible can save nutrients and supply female flower results.
1. Rhizomatous method: Starting from the bud emergence of female flowers, 80% of the male inflorescences on each loofah plant should be removed, and 20% pollination can be retained. Tendril plays a role in climbing and delineating vines in a vine crop. Loofah rolls have a long period of time from growing to pulling, and consume more nutrients, which is not conducive to multi-column melons and good melons. The removal of tendrils and the use of artificial binding instead of the climbing function are beneficial to the photosynthesis of plants, the production and accumulation of nutrients, and the prevention and control of diseases and pests, so that the loofah pollination is sound and fruitful, and the harvest is abundant.
2. In addition to the method: At the beginning of the growth of the loofah plant, adopt the method of removing the fringe and binding the vines on the scaffold. After the vines are evenly distributed and fixed on the scaffold, the tendrils can be removed at any time with the whole vine.
Fourth, timely prevention and control of pests and diseases
The disease is controlled with 72% Kelu 800 times solution or 70% mancozeb 800 times solution; downy mildew is controlled with 58% Ruidumye 600 times solution or 72% Kelu 750 times solution; powdery mildew 20% Triadimefon 2000 Double liquid control; aphids with 10% imidacloprid 1500 times the control; quail with 1.8 worms g 2000 times or Bacillus thuringiensis preparations such as prevention and control; fruit fly with 48% Lost 1000 times liquid control.
