Gourd planting technology from the soaking seed germination, land preparation and fertilization, planting methods, etc., gourd cultivation with artificial pollination, gourd management technology with water and fertilizer management and so on.
1, gourd planting technology
Soak seed germination: breeding gourd, you need to select the seed full and disease-free seeds, into the 55 ℃ hot water, and constantly stirring for 15-20 minutes, so that it absorbs enough water, and then put the gourd seed fishing into the formalin or potassium permanganate solution immersed for 10-15 minutes, to avoid the infected with diseases.
Full ground fertilization: Gourd is suitable for growing in humus-rich soil, when planting gourd, you need to plow 30-40 cm of land, make it more soft and breathable, and then apply to the soil a mixture of rotted organic fertilizer, straw, straw, rice bran fertilizer, is conducive to the gourd's vigorous growth.
Planting method: When planting gourd, you need to evenly spread its seeds on the soil surface, then cover a layer of 1-2 cm of thin soil, and then cover a layer of mulch, to increase the temperature of the soil, to promote the rapid germination of the gourd, and in the gourd after the emergence of seedlings, you need to pull out the weak seedlings of the poor growth, so as not to gourd growth is poor.
2, gourd cultivation technology
Artificial pollination: breeding gourd, the need to plant in the flowering of the plant for its artificial pollination, you can choose to carry out in the evening every day, you need to remove the flowers of the larger and brightly colored male flowers, and then the male petals to the back folded back, and then the pollen in the male flowers applied to the female flowers, is conducive to improving the rate of gourd fruiting.
3, gourd management technology
Water and fertilizer management: gourd on the water and fertilizer needs a large amount of fertilizer, need to be repeatedly fertilizer. Fertilizer available manure, organic fertilizer or composite fertilizer, - generally in the flowering and fruiting period before, every 3-4 days after the application of 1, into the fruiting period, with the water after application, according to each 667 square meters of 20-30 kg of composite fertilizer is appropriate. Gourd like complete fertilizer, avoid single application of nitrogen fertilizer.
Should pay attention to the nitrogen, phosphorus and potassium with the best application of organic fertilizer and compound fertilizer. When flowering and sitting on the melon, watering should be controlled to prevent melonization. After entering the fruiting period to timely watering, summer heat, should be in the morning or evening watering. Pay attention to flooding in the rainy season to prevent waterlogging and root injury.
Gourd powdery mildew control methods
1, agricultural control
Select higher terrain, good drainage and irrigation plots planting gourd; reasonable, dense planting, to remove the old leaves in a timely manner, as well as diseased leaves. Scientific watering, reduce humidity, adequate bottom fertilizer, Po Shi phosphorus, potassium fertilizer, growth in the later stages of timely fertilizer, prompt plant robust growth, enhance the resistance to disease.
2, pharmaceutical control
Early in the disease spraying, with 10% phenyl ether metronidazole water-dispersible granules 1000-2000 times liquid, or 15% triadimefon wettable powder 1500 times liquid, or 62.25% nitrilobenzene - Manganese Zinc Wettable Powder 600 times liquid, or 25% tebuconazole water emulsion wattle 3000 times liquid, every 10 days to apply a time, 2-3 times in a row. The agents should be used in rotation.
The agents for the control of this disease are 75% chlorothalonil wettable powder 500 times liquid, 25% powder rust Ning wettable powder 1500-2000 times liquid, 40% polysulfide gel suspension 1000 times liquid. It can be sprayed every 7-9 days, 2-3 times in a row, and the above agents should also be used alternately to prevent the germs from developing resistance.
