Problems solved by technology

Watermelons have a large demand for calcium, ranking third, close to nitrogen. Traditional fertilization only pays attention to the application of balanced compound fertilizers such as Norway (15*3), which often results in excessive nitrogen, insufficient potassium, and calcium deficiency. The color is not red, the sugar content is low, the defects such as umbilical rotten melon, hollow melon and yellow heart melon increase
[0005] And for watermelons, different types of elements are needed in different periods. For example, the demand for calcium in watermelons is greater than that of nitrogen during the vine stretching period. The ratio of nitrogen and calcium is imbalanced, and the nitrogen is too much. When the humidity is high, it is easy to cause the melon vines to grow excessively, resulting in low yield of the first batch of melons.

Embodiment 1

[0055] Embodiment 1 The first batch of melons is cultivated (according to the amount of fertilizer and drug use per mu of soil)

[0056] 1. Soil preparation and plowing

[0057] Till when the soil is dry, 30-40 cm deep.

[0058] 2. Base fertilizer application

[0059] Sumisho 10 kg + Fengxi calcium ammonium nitrate 10 kg + potassium magnesium sulfate (purchased from American Meisheng Company) 10 kg + Granebor 400 g, mix evenly, and directly sprinkle it into the soil.

[0060] Operation after fertilization: When the ground is dry, scrape the ground, break up the soil clods, open inter-row ditches and surrounding ditches, flatten the field surface, and make the furrow surface.

[0061] 3. Production of nutrition bowl

[0062] Seedling cultivation in 32-hole plug trays: Nutrient soil prepared with peat moss has poor moisture retention, and it needs to be watered frequently with 600 times of root calcium supplementation. Sprinkle with a watering can until the nutrient soil is ...

Embodiment 2 2 5

[0099] Embodiment 2 Two to five batches of melons (calculated by fertilizer per acre of soil)

[0100] 2.1 The second batch of melons

[0101] 1) 2 batches of sitting melons: If the greenhouse watermelons are growing well, 2 batches of melons should be placed 5-6 days before harvesting. If the greenhouse watermelons are not growing well, use a fertilizer to jump the vines after harvesting and then sit the melons.

[0102] Fertilizer: use 1 fertilizer after about 3 / 4 of the watermelon harvest, 2.5 kg of micro-supplementary calcium for each mu + 500 grams of micro-supplementary magnesium + 5-7.5 kilograms of Long Dewei (15-15-15) and water to make 200Kg The mother liquor is drip irrigation.

[0103] Spraying: After harvesting, dilute 200 times with SK mineral oil (purchased from SK company in South Korea) + 1.8% abamectin 1000 times + 25% pyrimethamine 800 times, clear the garden once, spray 400 catties of liquid medicine 4 ~ 5 acres of land.

[0104] 2) 5-7 days after 2 batch...

Abstract

The invention relates to the field of pollution-free greenhouse watermelon culture and particularly discloses a growing method for a first batch of greenhouse watermelons and a second to fifth batch of greenhouse watermelons. According to the climate and growing characteristics of the greenhouse watermelons in the Yangtze River basin, fertilizer and pesticides are applied according to different growing periods of the watermelons, so that the watermelons at the different periods fully obtain required nutritional ingredients, stable, full and normal growth is maintained, the yield and the quality of the greenhouse watermelons are improved, and the pollution-free and high-quality greenhouse watermelons are obtained.

Description

technical field [0001] The invention relates to the field of planting watermelon in a pollution-free greenhouse, and specifically discloses a method for cultivating the first batch of watermelon in a pollution-free greenhouse and two to five batches of melon. Background technique [0002] Watermelon main root system, leaves alternate, with deep lobes, shallow lobes and entire edges. Fruits are spherical, oval, elliptical, cylindrical and so on. The fruit surface is smooth or ribbed, the epidermis is green-white, green, dark green, dark green, black, with fine reticulate or stripes between. The pulp is milky white, light yellow, dark yellow, light red, bright red and other colors. The meat is divided into tight meat and sandy flesh. Seeds flat, oval or oblong, smooth or fissured. Seed coat white, light brown, brown, black or brown, monochromatic or variegated. It is a long-day plant, likes strong light, and the light saturation point is 80,000 lux. Suitable for hot and ...
