Scientific planting techniques of muskmelon

Many of us have eaten melon. It tastes crispy, sweet and juicy. There is also a sweet smell of melon in the mouth. It is very delicious. Using it for cold salad or making fruit salad is a delicious appetizer in summer. Sales are very good after listing every year, so many people want to know how to grow it.

Scientific planting techniques of muskmelon

1. Select land, prepare land and make beds. The previous crop is non-Cucurbitaceae, and the sandy soil with good drainage is the best. After autumn ploughing, 3000 kg of high quality organic fertilizer is applied every 667m2, deep ploughing, overwintering, storing rain and snow, weathering soil and eliminating diseases and insect pathogens. Spring rake: heavy rake after soil pulping, leveling the land. Cover the border with plastic film before the Qingming Festival, increase the temperature and preserve soil moisture, ridge and ridge by 150 cm, 60 cm, 20 cm high, cover with plastic film, and apply all the base fertilizer. Generally, 20 kg of potassium sulfate ternary compound fertilizer is applied every 667 square meters. Double-film cultivation and planting in the shed at this time.

2. Sowing seeds. The sowing time is 5 cm, the ground temperature is stable through 12 ℃, and the suitable sowing time is 20 days in this area from April 15 to 20. Sowing first under the film dark irrigation watering, reserved shallow ditch under the film, watering with a stick to support the film mouth, watering with this method watering every 667 square meters of water consumption of more than 10 square meters, more water-saving than flood irrigation. After the water seeps, punch and plant, 3-4 grains per hole, covered with wet soil 2 cm. The density of seedlings is equal to 2000,2500 seedlings per 667 square meters.

Matters needing attention in muskmelon planting

1. Application of fertilizer: special attention should be paid to the application of potassium fertilizer during the growth period of muskmelon, which can obviously improve the quality of muskmelon. In order to control nitrogen fertilizer, excessive application of nitrogen fertilizer will not only reduce the sweetness of muskmelon, but also cause excessive nitrite accumulation, which is harmful to human body. The principle of "controlling nitrogen, applying phosphorus and increasing potassium" should be grasped in the fertilization of muskmelon, and the combined application of nitrogen, phosphorus and potassium should be achieved.

2. Watering key points: after planting, the melon should be watered 2 times and 3 times. After the first time, when most melons grow to the size of eggs, 30 kg of ternary compound fertilizer will be applied with 667 square meters of water. Later, according to the environment and growth conditions, watering and topdressing according to local conditions should be avoided, dry and wet, so as to prevent cracking.

3. Pruning essentials: extensive management and simple pruning, that is, when the field leaf area coefficient is large in the middle and later stage, the top is simply topped with a stick to prevent the field from being covered. Double-vine pruning can also be used: when the main vine is 3-5 leaves, two strong-growing vines are selected and extended evenly to the border surface, and the sun vine knot melon, leaving 2 leaves in front of the melon to pick the heart, 1 for each grandson vine and 3-5 for each melon plant.

Application of inflated melon fertilizer

It should be carried out in the sunny morning, so the temperature is low, and the root activity will not be blocked due to the sharp drop of ground temperature after watering, resulting in leaf wilting and even plant death. When topdressing and 2-3 days after topdressing, the plastic film in the greenhouse should be exposed to increase ventilation to prevent ammonia from burning leaves during the conversion process. Stop the supply of fertilizer and water about 10 days before ripening, otherwise, it is easy to cause "reverse" or "stuffy" inside the fruit. Spraying Zhuangguatiling at the right time can thicken the pedicel, strengthen the directional transport of nutrients, and promote the rapid development of the melon body. the melon is beautiful, juicy and delicious, and the growth cycle is not falling flowers, no falling melon, no crack melon, no malformed melon.

Insect control of muskmelon

1. Muskmelon downy mildew. Prevention and treatment: reduce the humidity in the shed as much as possible. Such as pouring small water frequently, and avoid flood irrigation. Before the onset of the disease, use 68.75% DuPont easy to protect 1000 times or 75% DuPont to kill 1000 times for prevention, 10-15 times. At the initial stage of the disease, 72% DuPont Kelu 600x or 52.5% DuPont suppressed net 2000 times for treatment, 7-10 yuan at a time.

2. Vine blight of melon. Prevention and control methods: in the shed and avoid flood irrigation, using ventilation, pouring small water and other measures to reduce the humidity in the shed. After muskmelon was planted, it was protected by foliar spraying with 68.75% DuPont 1000 times or 75% fierce killing liquid 1000 times, once every 10-15 days. After the attack, use DuPont Fuxing 6000-8000 times or 20.67% Wanxing 2000-2500 times for treatment. If you need to smear the disease site, the drug concentration should be increased.

The most important thing in the cultivation of muskmelon is to understand its growth environment, and it will survive best only in a suitable environment. And melons are drought-tolerant but cannot have stagnant water, so the drainage system should be in place so as not to cause withering or even decay after stagnant water.
