Early spring melon cultivation technical points, it is recommended to collect
The melon is also called melon. It is a common kind of fruits for us. The melon taste is sweet and juicy, and many people like to eat. It has a very high planting prospect. Now the cultivation technology of the sun -shaped greenhouse in the early spring of the sunlight is relatively mature. Today, I will introduce it to you.
1. Sowing seedlings
When groaning seedlings, seedlings are generally adopted. Choose a greenhouse that has not been planted in nearly 2A as the seedling land. Due to the high temperature in July, the focus of seedling at this time is to reduce temperature and humidity to prevent tall seedlings. The seedling greenhouse and transplanted shed thin film were lifted to the edge of the insect -proof mesh for four weeks, and the two ends of the sheds were also fixed, leaving only the roof of the shed to avoid rain.
The top of the seedling shed covered the shade of the shade net. There are many rainfall in summer, and seedlings should be selected as high -ended places. 40 % of the field soil with unsolved melon, 40 % of the carbon soil, 20 % (or cow dung) of rotten chicken feces, per M nutritional soil Add di ammonia and urea LKG, 100g of polymorrholite, and wait for the use of full mixing. Before sowing, keep the soil wet until the seedlings are not emerged. Generally, seedlings can be emerged in 7 to 10 days. After emergence, pay attention to the harm of diseased insects. Pests have aphids and yellow guard melons, which are controlled by nagoline and mimamine insects.
2. Fertilization of land
After the previous stubble peppers are poured, the old leaves are picked up to pick up the ground, 40kg of three yuan compound fertilizer for potassium sulfate per 667 square meters, 150kg of organic fertilizer, and rolled the whole flat rake. Each shed is 4 畦, 1.5m width, and ridges in the tadpoles. The monopoly width is 40cm, the height is 15cm.
3. Field management
When transplanted when the melon seedlings 3 leaves and 1 heart are transplanted, the seedlings are poured in time after transplanting the seedlings (about 7 days after planting). During the period of time, the climate is observed at any time. When the soil is dry water. When the melon seedlings grow to 8 leaves, the main stem is broken, and the growth of the vines will be cut off. When cutting, the stem should not leave the leaves. When the child grows to 10 leaves, the tip is tip. When the female flower is flowers, leave two slices of functional leaves after the melon, and the side vines on the armpit of the front lobe in the melon should be removed in time to avoid affecting the fruits. During the whole process, the vines should be achieved, and each vine strip should be evenly raised to the square to make the leaves evenly light.
If you find that Sun Man or Sun Sun Man has not appeared in female flowers, you should put it off in time (leaving 2 leaves) to avoid consumption of nutrition. It should be noted that the growth potential of melon in summer does not have a strong growth potential in spring, so the whole pruning cannot be too fierce, so as not to affect nutrient transportation too much. When the melon grows to the egg, the fruits are as small as the egg, and each plant removes crooked melons and stiff fruits. 4 to 6 to 6 to 6 to 6 to 6 to 6, it is not easy to stay. Water after the fruits, 20kg of dilate ammonium phosphate with water, and 15kg of potassium sulfate. During the subsequent birth, leaf fertilizer can be sprayed every 10 days to increase nutrition. The maturity time of the melon fruit varies from varieties of different varieties. Generally, about 26 to 35 days after flowers, there are slight depression at the umbilicus at the umbilicus.
4. Diseases and insect worship prevention
The diseases of melon mainly include withered disease, vine blight, viral diseases, etc.; Insect pests are mainly aphids and live lice, and the seedlings are also harmful to yellow guarding melons. Prevention and treatment can be used with 72.2 % Pulker water 600 times liquid or 70 % Antaiosheng wettable powder 400 times liquid; when the onset of the onset, it can be used to spray it with 100-150ml of water and 15kg of water. Powder 500 times liquid irrigation, 25-30 trees per barrel;
2 % agricultural resistance 120 water doses 200 times liquid to the middle and lower part of the plant for 2 % agricultural resistance. You can also use 25 % Amisida 30 times liquid to apply stems after scraping the disease; 0.5 virus disease is 0.5 % Mushroom polysaccharide water / 667 square meters or virus A wettable powder 500 times liquid spray control. Crystal Gua, aphids, and livelings are 24 % anti -pheoprid wettable powder 15 ~ 20g / 667 square meters or 40 % limedine pyrite soluble powder 3 ~ 5g / 667 square meters or 25 % carotazine water dispersed agent 8-15g / 667. 667 Flat meter.
