Cultivation method of greenhouse watermelon

Abstract

The invention discloses a cultivation method of a greenhouse watermelon. The method comprises the steps of seed soaking and germination accelerating, seedling, greenhouse building, field planting, greenhouse temperature management, fertilizer management, pruning and harvesting. Through entire greenhouse coverage of planting, rainwater and insect pests are effectively reduced, the life ability of plants is improved and the quality of a watermelon product is controlled. The growth quality of the plants is ensured and regeneration of the plants is promoted through the processes of strictly controlling the greenhouse temperature and controlling the fertilizer variety, the fertilization time, the fertilization amount and the fertilizer concentration, premature senescence is prevented and the growth period is prolonged, so that the effect of improving the yield through multi-batch harvesting is achieved. By using the cultivation method, the growth period of the watermelon is prolonged to about 6 months from 3-4 months, the harvest time can reach more than 4 months, 3-5 batches of watermelons can be harvested and the average acre yield reaches about 6,000kg, so that the land yield rate, the resource utilization rate and the labor productivity are improved to the maximal extent.

Description

technical field [0001] The invention relates to the technical field of watermelon planting, in particular to a cultivation method of watermelon in a greenhouse. Background technique [0002] Watermelon is an annual vine herb of Cucurbitaceae, which has a long history in my country. Watermelon Watermelon tastes sweet and juicy, refreshing and quenching thirst. It is a good fruit in midsummer. Apart from fat and cholesterol, watermelon contains a lot of glucose, malic acid, fructose, protein amino acids, tomato element and rich vitamin C. It is a nutritious food. , Pure, safe food. In recent years, the watermelon planting area has also shown a trend of increasing year by year. For watermelon cultivation, fertilization is particularly important. Different types of elements are required in different periods. For example, the watermelon needs more calcium than nitrogen during the vine extension period. Melon production is low. However, the content of calcium in watermelon fru...
