Continuous cropping cultivation method for high yield of watermelon

Abstract

The invention discloses a continuous cropping cultivation method for high yield of watermelon, and belongs to the field of watermelon cultivation. The method includes the following steps: land selection and land preparation, selecting land in a watermelon land where no or rarely found dead seedlings due to fusarium wilt in the previous year; applying a base fertilizer, wherein the base fertilizeris mainly a fully fermented and decomposed organic fertilizer and is supplemented by a chemical fertilizer; selecting a disease-resistant improved variety, and selecting a watermelon new variety ZhengKang No. 1 which is resistant to continuous cropping and fusarium wilt; seedling raising and field planting, soaking naive seeds for 45 minutes with formalin 100-fold solution with a concentration of40%, disinfecting the seeds, washing the seeds with clear water, and soaking the seeds in warm water at a temperature of 35DEG C for 120 minutes; and field management. The method is scientific and reasonable, overcomes obstacles of continuous cropping, and has high yield.

AI Technical Summary

Problems solved by technology

[0003] Continuous cropping of watermelon is prone to devastating damage caused by soil-borne diseases such as fusarium wilt, and its cultivation is very difficult. Usually, long-term crop rotation (8-10 years) is adopted for cultivation. With the expansion of watermelon planting area, the planting area of ​​old melon areas is limited, so Corresponding technical measures have to be taken to overcome the obstacles of continuous cropping
