1, fertilization period:
1 Base fertilizer is applied before sowing and planting. The main organic fertilizer is mainly delayed organic fertilizer, which accounts for 60% to 80% of the total amount of fertilizer. After the field is spread, it is ploughed or fertilized on both sides of the melon groove. Gully application is also applied to basal fertiliser in advance during autumn farming.
2 Topdressing is carried out during the growing period of melons, mainly using quick-acting fertilizers, which can be applied in batches at the seedling stage, vine extension stage, fruit setting stage and fruit development stage. The method is to dig a hole in the melon line or apply it with irrigation water.
2, fertilization method:
1 Basal fertilizer should be re-applied organic fertilizer, and the decomposed manure (such as pig manure, sheep manure, chicken manure, etc.) 8-10 square meters, 50 kg of potassium sulfate, 50 kg of diammonium phosphate, or 50 kg of potassium sulfate compound fertilizer should be applied per acre. Then deep into the peace. Or Mushi rot composting good manure 2-3 side, microbial fungus 200-300 kilograms (you can apply each toy hole Toyota 3), 45% of potassium sulfate compound fertilizer 50-75 kilograms. Or general Mushi chicken manure 3 to 5 squares, biological organic fertilizer 200 to 300 pounds, without the use of chicken manure with biological organic fertilizer with 700 to 800 pounds, potassium sulfate compound fertilizer with 80 to 100 pounds, trace elements Fat 20 pounds.
2 Disinfection of old shed soil Mushi 50% carbendazim 3 kg or enemy kousong 1.5 kg mixed fine sand 25 kg, plowing the ground sprinkled on the ground, while adding 0.5 kg of phoxim or 48% of Bassin 0.5 kg spray Ground, soil disinfection.
3 In previous years or in severely affected plots of root-knot nematodes, the control of root-knot nematodes must be strengthened. Select nematocide (avermectin, thiazole-phosphine, or avermectin and thiazole-phosphine reconstitution agents). Or acupuncture points. The specific use of methods: plough before spraying nematode granules per acre, and then spin. Or apply first, apply a certain amount of mixed soil before planting, or apply all the soil to the soil before planting.
4 After the use of basal fertilizers and nematodes, they can be ridged and ridged, and they are usually cultivated in high and low levels. The ridge height is 20-30 centimeters. Two rows are placed on the ridge. The row width is 60 centimeters wide and the width is 90 centimeters wide. (The early-maturing cultivars are 35-40 centimeters in length, 40-45 centimeters in mid-late maturing cultivars, and 1800-2000 cultivars in mus.) After starting a ridge, pour a large amount of water 10-15 days before planting. First, level the ground. The second is that early rising temperatures are conducive to returning seedlings later.
