First, the selection of species regardless of the type of watermelon, or late watermelon, are selected strong drought resistance, strong growth, resistance to pests and diseases, a high sitting rate, melon shape, high quality, high yield and stable production varieties.
Second, the choice of watermelon likes to produce wasteland, avoid bountiful, with loose soil and fertile and dry irrigation, can be ranked as the best place.
Third, fertilization is dominated by organic fertilizers, and more livestock and poultry manure, cake fertilizers and biological fertilizers containing more phosphorus and potassium are used, and chemical fertilizers, calcium fertilizers and zinc fertilizers are applied in appropriate amounts.
Fourth, cover film mulching film, grass ridges between the grass, drought, disease prevention, increased production of significant effect. Before deducting the film, if there is not enough dew, it is necessary to make up for it. Bottom hoe has a great effect on watermelon seedling drought-proof growth, promoting early maturity and winning high yield.
5. Watering Pay attention to the water supply at the sowing date, seedling stage, planting stage, seedling stage, vine spread and swell period, especially the flower bud differentiation period and the water supply of about 10 days before the female bud is an important period that determines the high yield of watermelon. can not be ignored. In order to avoid the loss caused by drought, soil moisture of watermelon seedlings should be kept well.
6. The pruning of the watermelon in the dry year is weak and the pruning should be adapted to local conditions. Some melon farmers have hit the leeches completely, making them unable to cover the land, lacking in nutritious areas, affecting photosynthesis, and not growing much. Under normal circumstances, as long as you can sit and eat melon can not fight. If the saplings are growing poorly, they can only pruning and not squatting or pruning with light pruning, which is a good way for the watermelon to win high yields in the dry year.
Seven, spray fertilizer leaf spray strong drought resistance of the fertilizer, hormones, trace fertilizer, can reduce water evaporation in plants, enhance water absorption capacity of the roots, drought and increase production significantly.
Eight, top dressing watermelon roots to absorb fertilizer, must have enough water to absorb and use. Otherwise, it is difficult for fertilizers to be absorbed and utilized, or even to burn roots. Therefore, the top-dressing of drought must be done in conjunction with watering, otherwise the workers and the people will suffer financial difficulties.
Nine, disease prevention Watermelon in the dry weather is less ill, but not sick: regular spraying and disease prevention can not be ignored, the effect of medication after the disease is poor, due to drought, watermelon pods prone to premature aging, once the disease is difficult to cure.
X. Insect pests prevent and control the weather more and more locusts become more and more. The locusts are eliminated at the spotting stage, and when the leaves become clumpy, the locusts are exterminated, and the labor costs are reduced.
11. Weeds must be removed from the weeds before they reach the vines. Weeds not only compete with watermelons for water, fertilizer, and light-grass, but also cause watermelons to become infected and die, resulting in poor quality and low yields. When the melon seal can't be scooped, using 200 times the catch can eliminate the grass and beechroot weeds. The effect is excellent.
