Method for improving yield and quality of watermelons through in-situ intercropping

Abstract

The invention discloses a method for improving the yield and the quality of watermelons through in-situ intercropping. The method comprises the following specific steps of: plowing the farmland to carry out soil preparation, ditching and rising beds of 140cm, and plowing flatly the beds or forming a bed surface in a shape of turtle back, wherein the width of each bed is 90cm, and the width of each ditch is 50cm; carrying out frame cultivation on the watermelon, transplanting after culturing large seedlings, and transplanting two rows of seedlings in each bed, wherein the plant distance is 40-50cm, and the line space is 70-750cm; laying a support when the vine of the watermelon grows to 15-20cm at the vine growing initial stage of the water melon, and guiding the vine onto the support when the vine of the watermelon grows to 50-70cm; paving a beer residue feed bed with the width of 80-90cm and the height of 6-10cm on the ground flatly among lines of watermelon plants after 5-8 days; inoculating earthworms according to the amount of 1300-1500 pieces per square meter after 10-15 days; and recycling the earthworms after the watermelon is harvested, and turning over the waste beer residue under the farmland to increase the soil organic matters and improve the soil fertility. After the method disclosed by the invention is adopted to plant the watermelons, the physical and chemical properties of soil are improved and the side-products earthworms are harvested; and meanwhile, the yield, the nutrient content and the like of the watermelon are improved, the cost can be reduced, high-quality and safer fruits can be produced, and multiple economic benefits are obtained.

Description

[0001] technical field [0002] The invention relates to the technical field of watermelon cultivation, in particular to a method for improving the yield and quality of watermelons through in-situ interculture. Background technique [0003] Watermelon, also known as water melon, cold melon, summer melon, is the fruit of Cucurbitaceae watermelon. Because it was introduced from the Western Regions in the Han Dynasty, it is called "watermelon". The melon is round or oval, and the skin color is dark green, green, white or green with snake patterns.

In addition to being free of fat and cholesterol, watermelon contains a lot of glucose, malic acid, fructose, protein amino acids, tomato element and rich vitamin C and other substances. It is a nutritious, pure and safe food. food. From south to north, fro...
