Watermelon plastic film full-mulching cultivation method

Abstract

The invention discloses a watermelon plastic film full-mulching cultivation method. The watermelon plastic film full-mulching cultivation method comprises a first step of preparing a land and sowing laguminosae, a second step of evening the laguminosae, a third step of conducting irrigation and covering plastic film, and a fourth step of growing watermelon seedlings and conducting filed management. According to the watermelon plastic film full-mulching cultivation method, due to the fact that the land is fully covered by the two-color plastic film, the two-color plastic film has the effects of restraining weeds and avoiding aphids, the aphids and other insects are effectively prevented from spreading diseases, the land temperature inside a ridge is rapidly improved, and effective degradation of green manure plants is improved. Due to the fact that quick lime is applied, soil acidification can be effectively relieved, the calcium content of soil can be increased, and the rate of watermelon cracking in the watermelon mature period is reduced. Due to the fact that a layer of dry straw covers the plastic film arranged between every two ridges, moistures is absorbed, the dryness degree inside a green house is improved, fixation of watermelon vines is facilitated, and watermelon growth is facilitated. The incidence of fusarium wilt is reduced by 96% compared with that of the prior art. The quality of watermelons is remarkably improved. The sugar degree of each watermelon is increased by 1%-3%. The yield is increased by 200%-600% compared with that of the prior art.

Description

technical field [0001] The invention relates to a watermelon cultivation method, in particular to a cultivation method in which all watermelon planting fields are covered with plastic film, and belongs to the technical field of melon and fruit cultivation. Background technique [0002] Fusarium wilt, blight and other diseases often occur during the watermelon growth period, seriously affecting the yield of watermelon. Under normal circumstances, Fusarium wilt causes a loss of about 15-30% of watermelon yield, and some continuous cropping fields are as high as 50-85% with Fusarium wilt, or even no harvest. Fusarium wilt has become the main limiting factor of watermelon production. One of the reasons for the occurrence of Fusarium wilt is the decline of soil quality and the growth of pathogens in the soil, and the decline of soil quality will have an important impact on the microbial flora and soil enzyme activity in the soil, which is comprehensively manifested in the change ...

Problems solved by technology

In addition to common diseases such as Fusarium wilt and creeping blight, the existing watermelon cultivation methods are also prone to weeds, which take away soil fertility and affect watermelon yield.
