How to grow melon? Cultivation techniques of melon!
Melon contains malic acid, glucose, amino acids, vitamin C and other rich nutrients. Eating melon is good for the heart, liver and intestines. It has certain positive effects on water and dehumidification, lipid lowering and lowering. Cucurbitacin in melon can protect the liver and reduce chronic liver damage. In addition, melon seeds have the effect of killing aphids and filars. So how do you want to grow melon? What should you pay attention to during planting?
greenhouse
Soaking seeds and germination: The seeds to be sown need to be carefully selected. Before germination, it should be aired for 2 days, then soaked in warm water of about 50 °C for about 15 minutes, and pay attention to stirring. The water temperature is naturally cooled and then soaked for 5 hours, then removed and washed, and then disinfected with liquid. The commonly used medicine is 0.1% potassium permanganate for 2-4 hours; 500 times liquid 70% methyl thiophanate or 1000 times liquid 50% carbendazim soak for half an hour. The seeds soaked in the liquid are washed once with water, placed in a dish with a wet towel and placed in an incubator or on a hot steamed bread for germination. The temperature is controlled at 30 ° C, and the buds can be discharged in 14-24 hours. When the young shoots are exposed, the temperature drops to about 25 ° C, and drops to 13-20 ° C before sowing to prevent the heat from growing. Attention to fertilizer and water management during seedling period, it is generally not advisable to pour large water.
Colonization: Melon seedlings are planted in strawberry ridges from late March to early April with a plant spacing of 50 cm. When planting, add appropriate amount of soil fungicide and phosphorus and potassium fertilizer in the hole, 2 melon seedlings per hole, and pour enough water.
Pruning: Qitian No.1 Melon is mainly based on the results of Ziman and Sunman, and it is necessary to be flexible when pruning. When the melon seedling grows to 4 true leaves, the heart is picked, and each of the 1-4 leaf stalks grows with a vine. Generally, the vines near the root are removed, leaving the first 3 vines, each of which needs 4-5 leaves. Leave the sun vines and melons. It is best to make 5-6 melons per vine. If the vines are sitting less or unable to sit, you need to keep the vines and vines. Each vine is best to release 3-4 grandchildren. When the 4th leaf is used, the heart is picked again, and the whole plant is allowed to sit 4-5 sun vines. After pruning, it is more suitable to keep 6-8 melons per plant.
Fertilizer management: The growth season of melon needs a lot of fertilizer. In addition to applying the base fertilizer, it is also necessary to carry out top dressing. Phosphorus and potassium fertilizer can improve the quality of melon, generally apply more potassium fertilizer and less nitrogen fertilizer. The peak period of nitrogen fertilizer absorption during the growing season of melon was 2 weeks before pollination. Generally, 666.7m2 of topdressing fertilizer of about 5 kilograms of ammonium sulfate can be carried out together with watering. The young fruit expansion period (starting of melon egg size) is mainly based on potassium fertilizer, 46 kg of 666.7 m2 hole is applied, and foliar spray fertilizer can be applied once every other week. The soil moisture before the fruit setting is 70% of the maximum water holding capacity, the young fruit expansion period is 80%-85%, and the fruit entering the maturity period is 55%-60%. The moisture in the early stage should not be too much, in order to prevent the lengthening and falling flowers and fruit, the water supply period should be sufficient, and the water should be poured every 1 week.
Temperature management: Melon is a thermophilic crop with different temperatures for each growth period. After general planting, the temperature management must be grasped in the early stage. The high temperature management method should be adopted to maintain the temperature at 25-35 °C (15 °C-45 °C can also grow normally), the flowering period is 25 °C, if the night temperature is lower than 17 °C, The flowering period will be postponed and the optimum temperature for fruit ripening is 30 °C. During the growing season, melon stops growing when the temperature drops to 13 °C, and stops growing completely at 10 °C. Cold damage occurs at 7.4 °C. In the early spring, the climate change is impermanent. It is necessary to do a good job of cold insulation measures, combined with foliar application of K-3 anti-reverse stimulation agent, the effect of resisting low temperature will be better.
Hydroponics
Cultivation facility
1. Build a rainproof shed and insect net. The shed is covered on the steel pipe shed, and the sheds on both sides are suspended from the circlip groove by 0.8-1 m, and the skirt is under the skirt. When it rains, the shed film on both sides is put down for rain, and the two sheds are open and ventilated. The shed film is covered with a layer of 40 mesh insect net (including the shed head), which is reinforced with a film line to prevent blasting.
2. Hydroponic facilities. Hydroponics was carried out using a sponge micropipette. Hydroponics facilities include cultivation systems, circulation systems, and control systems. A sponge of 35 cm width and 2 cm thickness was placed in the cultivation bed, and a micropipette with a filtering device and a hole spacing of 20 cm was placed on the upper surface, and the dropping holes were upward. Thoroughly clean the environment inside and outside the greenhouse before disinfecting the facility, and do a good job in disinfecting the cultivation facilities and the ground. The shed film is disinfected with formalin 100 times liquid, and the cultivation bed, liquid storage tank, water pipe, etc. are soaked and washed with 0.5% bleaching powder solution, nutrient bowl, micropipette, sponge are soaked or poured with boiling water, and ground lime is applied. Cover the mulch.
Cultivate strong seedlings
1. Variety selection. Choose pearls 200, West Boluo and Yulu, which are resistant to disease, heat, fruit, high yield and high quality.
2. Sowing date. Sowing in the middle and late July, the fruit expansion period is September, and the ripening period is in October. This phenological period is conducive to the expansion of melon fruit and increase the sugar content of the fruit.
3. Sowing. The seeds are disinfected with 10% trisodium phosphate or 40% formaldehyde 100 times, and then seeded in a seedling tray of ash (pH 5.5-6.5), covered with a sunshade, placed in a rainproof shed.
4. Seedling management. In the autumn, the melon can be emerged 3 days after sowing, and the shading on the seedling tray is removed to keep the ash matrix moist. After the heart leaves are unfolded, the seedlings are soaked for 10 minutes with 800 times of root disease, then planted on the nursery bed, and covered with black shade net to avoid direct sunlight.
5. Colonization. The standard of strong seedlings is: the branches and leaves are intact, no pests and diseases, the leaves are thick green and thick, the stems are thick and strong, the knots are short, and the roots are white and complete. The seedling age is in 20-25 days. A few days before planting, the shading net on the seedbed was removed to refine the seedlings, and the chlorothalonil 800 times solution or carbendazim was sprayed once. At the time of planting, the roots of the seedlings were placed in the net 800 times solution of the root disease for 5 minutes, and then planted in the cultivation bed. Three cultivation beds are laid in a 6-meter-wide shed. The length of each bed is no more than 20 meters. Each shed is planted with 6 rows, 2 rows per bed, with a plant spacing of 40 cm, and 1500 seedlings per 667 square meters.
