Cucumber is a common vegetable. It was only planted in the south. Because it is very popular in the vegetable market, and the north is growing, how do you know how to produce high yield? If you don't know, you can follow the small series.
The requirements of the melon for growing environment
The melon is warm, but it is not very resistant to high temperatures, nor is it resistant to low temperature frost. The short-day sunshine plants of the genus Melon can delay the emergence of female flowers in the main vines during the seedling period, and the opposite effect can also be achieved by disposal with ethephon.
The melon has a wide adaptability to the soil, and it is suitable to use a humus-rich soil that retains water and maintains fertility. Avoid rotation. The nutrients required for the melons are mainly nitrogen, and the phosphorus and potassium fertilizers are used in cooperation with each other, so that the yield and quality are advanced. The melon has strict requirements on moisture, and it is not resistant to early and unbearable.
The period of action is relatively high. If the air is too wet, the leaves, flowers and tender fruits are simply simmered. In rainy areas, it is necessary to pay attention to drainage. When drought occurs, it should be irrigated in time. There are differences in the development of the roots of the melons, as well as the types of the elements. The long-rooted melon is a shallow root system, and its prosperous root system is mainly scattered within 20 cm of the topsoil and is not resistant to drought. The roots of the round gourd are deep into the soil and have strong drought tolerance, but they are not resistant to cockroaches.
The requirements for light conditions are high. Under the condition of sunlight, the growth effect is good and the disease is less; the effect period is sunny, the growth and effect are outstanding, and the yield is high.
Selection
Summer melon cultivation is suitable for cultivation in areas with a low sea pressure of 200 meters or more. Varieties should be selected for high-compatibility varieties with strong adaptability, good disease resistance, long melon weight, single melon weight, thin skin, good gloss and high temperature resistance. In the meantime, two varieties of Anjiqingpi long melon and Wuhan long melon are better. .
Land selection
To obtain high-yield melons, it is important to choose plots. The cultivated land should be selected from a flat area, a sunny place, an easy-to-discharge irrigation, a convenient traffic, and a large area with a large area. The soil is selected from soils with thick humus, soil loose and fat, strong water retention and excellent drainage.
Soil preparation
Plowing once before the whole land, about 5,000 kg of farmyard manure and 50 kg of ternary compound fertilizer per mu. After shallow ploughing, it is tidy, with a width of 1.0 m and a width of 0.3 m. Open the waist groove and circle together to facilitate drainage.
Sowing seedling
1. Seeding time: The time of listing of alpine melons must be between the high temperature and the lack of water (8-September), because the summer planting melons are shorter than the spring sowing melons. Therefore, the suitable sowing date should be selected at the end of May. Until the beginning of June.
2. Seed disposal: Before sowing, the seeds of the melon seeds should be treated with warm water intermittent soaking, prepare the equal weight of 65 °C warm water according to the weight of the seeds, pour the seeds into warm water, mix together from time to time until the water temperature drops to about 25 °C. Soak the seeds in water for about 1 hour, remove the seeds and wash away the impurities attached to the seeds with clean water. Soaking the warm soup can promote the water absorption of the seed, break the seed's firmness, advance the seed's germination rate and germination potential, and advance the seedling's regularity; together with the warm soup soaking, it can kill some eggs and pathogens attached to the surface of the seed, and increase the occurrence of pests and diseases.
3. Seeding and seedling: The amount of seeds used per acre in the field is 300-400 grams. Because the seed coat of the melon seeds is thick, it is not easy to see through. Disinfect with 0.001 concentration of potassium permanganate for 10 to 15 minutes, then soak for 8 hours. Seedbed seedlings are selected, and the seedbed is 5-6 square meters per 667 square meters. After sowing, gently press the surface with a flat plate, then cover the soil and pour water. Because the summer temperature is high and the climate is monotonous, to make a moisturizing method, cover the double-layer shade net on the surface.
4, seedling care: seedlings should prevent excessive nitrogen fertilizer, to ensure that there is a satisfactory light. If the climate is dry, watering should be carried out in the morning and evening to keep the seedbed moist, in order to facilitate emergence.
Transplanting
When the melon seedlings reach 2 cotyledons, it is the colonization period. The planting density is about 2300 plants per acre, and the plant spacing is 40-70 cm. Before the planting, the seedbed should be watered to prevent damage to the roots when the seedlings are taken, slow seedlings, affecting plant growth, and then affecting early yield. Before the planting, it is necessary to control the underground beneficial insects such as the tiger. The time of planting should be chosen to be interrupted at 4 pm on a cloudy or sunny day. It is necessary to set the root water with 800 times of carbendazim while planting. Watering the roots every night or 2 to 3 days later.
Field care
Rack cultivation: The melon-shaped melon is generally used for the melon-shaped melon. After the vine is used, the end of the frame is set, and the center is provided with 2-3 lanes.
Separation of fruit: The melon is mostly vine with side vines. The main vine grows to the first time to pick up the heart for about 50cm, in order to facilitate the early occurrence and action of the side vine, and advance the yield per plant. Choose a strong female flower on the vine, and leave 1-2 leaves in the upper part of the female flower. But keep the top of the top vine, instead of the main vine. After that, the surviving Sun Man was topped out as before, and the lower old, yellow and diseased leaves were removed in time. In order to make the female flower nodes of the melons low, 150-200mg/L ethephon solution can be sprayed in 4-6 true leaves, but for the pollination needs, 1/4 seedlings should not be sprayed. In order to advance the fruit setting rate, the artificial pollination can be stopped after the flower is closed at about 6 pm on a sunny day.
Water and fertilizer care: high yield of melon, high water consumption, need more fertilizer, in addition to the application of base fertilizer, the first stage of growth, the application of dilute human excrement 1-2 times, after the topping, the application of manure 1 time, the late growth potential, fruit More, should be watered in time, especially in high temperature and drought, the harvesting period should be at least once a week, every 1-2 batches of melon should be topdressed once, each compounding 15-20kg and urea 5kg per 667m2 to prevent premature aging Increase the output in the later period.
I think most people know how to grow melons, but it is hard to say if they can produce high yields. Interested parents can collect the high-yield cultivation techniques of summer melons shared by Xiaobian.
