How does winter melon manage high yields:
First, sowing seedlings: Because melon is thicker than seed skin, it is not easy to absorb water. Before planting, build a seedbed, use fertile soil that has not been planted with melon crops, apply enough base fertilizer before planting, and pour enough water. • Seed soaking and seed disinfection should be carried out (soaking with 50% carbendazim 250 times solution and new high fat film 800 times solution for 20 minutes, disinfected seeds washed with water and then immersed in 800 times solution of new high fat film 5 - 6 hours, pick up for germination, germination temperature is about 30 °C is appropriate). After sowing, the new high-fat film 800 times liquid should be sprayed in time to protect against drought, prevent soil layer compaction, and increase the emergence rate.
2. Planting management: Select new land that has not been planted with melon crops or plant that has been subjected to water and drought rotation for 3-5 years, and apply sufficient base fertilizer (2000-3000 kg of organic fertilizer per acre, 50 kg of superphosphate) . Rift and land preparation. The dough is made 110-120 cm, the groove width is 50 cm, and there are ring grooves around the field block to reach the ditch and the channel to facilitate drainage. Reasonable close planting. When the temperature is stable at 15 degrees Celsius or above, the transplant is selected on a sunny day, and each row is planted at a distance of 60-70 cm. 450-550 plants per mu, after planting, root water is sprayed, and the new high-fat membrane 800 times liquid is sprayed to protect the seedlings in time to prevent the infection of the bacteria and improve the ability to resist natural disasters, so that the seedlings can smoothly pass through the seedling stage.
Third, promote flowers and strong fruit: seedlings should be followed by timely application of strong seedling fertilizer compound fertilizer 10-15 kg, urea 8-10 kg, must be combined with spraying to promote Huawang 3 to inhibit the main shoots mad, promote flower bud differentiation, Make it more flowering and more fruit; spray the strong melon timidine to promote the nutrient transport before the flowering of the melon, before the flowering stage, and during the fruit expansion period, and promote the rapid development of the melon body. When the fruit grows to 3-4 kg, it will be used to grow the melon. Fertilizer, 15-20 kg of compound fertilizer, 10-15 kg of urea and 8-10 kg of potassium chloride. Apply once every 10-15 days, continue to apply 4-5 times, and timely irrigation. Fourth, pest control. The main pests and diseases of winter melon are: blight, blight, cockroach, melon, horse, melon, etc. It is necessary to spray targeted drugs (such as 70% dikesone, 80% dichlorvos, etc.) with new high-fat film 800 times. Effective prevention.
