High-yield planting techniques for summer melon

The requirements of the melon for growing environment

The melon is warm, but not very resistant to high temperatures, nor is it resistant to low temperature frost. The short-day sunshine plant of the genus Cucurbita 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 for the soil with high humus-rich water retention and fertility. Avoid the rotation. The nutrients required for melons are mainly nitrogen, and the excessive application of phosphorus and potassium fertilizers is applied, so that the yield and quality of the products 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, and when it is dry, 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 sun-satisfying area, an easy-to-discharge irrigation, a convenient transportation, 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 one shallow ploughing, the raft is 1.0 m wide and the ditch is 0.3 m wide. 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 low temperature (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, and 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 seeds can promote the water absorption of seeds, break the seed's firmness, advance the seed's germination rate and germination potential, and advance the regularity of seedlings; together with warm soup soaking can kill some eggs and pathogens attached to the surface of seeds, increasing the occurrence of pests and diseases.

3, sowing seedlings: the amount of seeds per acre of 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. At the time of planting, you should choose to interrupt at 4 o'clock in the afternoon on cloudy or sunny days. 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, and the end of the vine is used for the truss, and the center is provided with 2-3 lanes.

Pruning fruit: The melon is mostly side-grown, and the main vine grows to about 50cm for the first time to pick the heart, so that the side vines occur early and function, and the yield per plant is advanced. 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 part of the 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 on 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, 1-2 times of manure excretion in the early stage of growth, after the topping, the application of manure 1 time, the late growth is prosperous, fruit set 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, every 667m2 compound fertilizer 15-20kg and urea 5kg to prevent premature aging Increase the output in the later period.
