In recent days, several farmers have consulted and their loofahs have flourished, but they do not produce melons. This is caused by the typical melon growth. Xia Shougua has a high temperature in the growing season. If it encounters continuous rainy weather, it will not be properly managed. It will result in leggy, lack of melon or fruit, and will seriously affect the yield and economic benefits. To control the longevity of loofah, the following four points need to be done.
First, nurture healthy seedlings
Choose a variety that is suitable for summer cultivation and is insensitive to short days. The loofah seeds are sunned for 2 to 3 days, soaked with fresh water for 8 to 10 hours, picked up and drained for sowing. Before the seedlings are transplanted, the fertilizer and water should be properly controlled to cultivate strong seedlings. When the seedlings have 2 to 3 true leaves, they can be moved to Daejeon.
Second, timely introduction of vine pruning
After planting, timely vine leaf finishing was performed, and the number of mango vines was 2 times. Generally, the vine was first crushed at a length of about 35 cm, and a second vine was grown at a length of about 70 cm. When the male flower appeared, it was introduced onto the shelves. After being put on the shelves, the zigzag was used to draw the vines evenly. In the case of overgrowth of vine leaves, parts of the leaves can be removed at different parts of the upper, middle, and lower parts of the leaves, or the leaves can be taken in places where the vine leaves grow too densely, which is conducive to ventilation and light transmission or reduction of pests and diseases. At the same time, we should remove the diseased melons and spray them to disinfect and disinfect them so as to avoid infectious diseases.
Third, water and fertilizer management should be properly
Loofah like fertilizer, should choose Xiangyang, soil fertile, moist, high organic matter content, water retention and fertility of the loam field cultivation. The principle of top-dressing is to dilute and apply thin plants, control the fertilizer and water before squashing, and apply heavy fertilizers after squashing and lateral vine spreading, and pay attention to the application of phosphorus and potassium fertilizers. After transplanting for 5 to 7 days, mu was applied with 1,500 kg of 1:10 diluted feces and urine. Fertilizer depends on seedling conditions until flowering results: seedlings grow vigorously, dark green, you can apply less or no fertilizer; grow weak, every 15 days per acre applied 4 to 6 kg of compound fertilizer leaching solution 1500 kg. After the results, the fertilizer was applied once every 5 to 7 days, and each application of compound fertilizer was 10 to 15 kilograms per mu. The amount of fertilization during the harvesting period should be increased by 1 to 2 times, and 1 to 2 times of plant ash should be added. 50 to 100 kg. Loofahs need more water during the whole growth period, and the soil should be kept moist during the early growth stage. Irrigation should be strengthened during the flowering of the plants. When irrigation, irrigation should be performed immediately, without flood irrigation, and rain should be drained in time to prevent flooding.
Fourth, spray growth regulator
In combination with spraying foliar fertilizer, before the flowering loofah, young fruit stage, and fruit expansion period, they sprayed “vegetable fruit and bolognese†to control vegetative growth, promote reproductive growth, and early flowering and early fruiting. In the case of continuous rainy weather, the “new high-fat film†can be sprayed at appropriate times to prevent flooding and mitigate the adverse effects caused by natural disasters.
