大棚栽培蔬菜,产量高,效益好,但因连茬栽培,土壤中的枯萎病、蔓枯病、疫病、黑星病等随着连茬蔓延,严重影响蔬菜生产。虽然采取挪棚、嫁接、换土、轮作等措施,有一定效果,但在生产实践中用起来,都有一定难度。用稻草、石灰混合物高温灭菌,方法简单,花钱少、效果好,还能就地取材,不用农药减少蔬菜污染,提高产量,增加效益。在冬春茬蔬菜拉秧后的7—9月份,彻底清除菜秧的残枝落叶,每100米长棚(约600平
Greenhouse cultivation of vegetables, high yield, good efficiency, but due to continuous crop cultivation, soil fusarium wilt, blight, scab, black star disease with the stubble spread, seriously affecting vegetable production. Although some measures have been taken, such as carrying a shed, grafting, changing soil and rotating crops, it will have some effect. However, it is difficult to be used in production practice. Sterilization with straw and lime mixture at high temperature has the advantages of simple method, low cost and good effect, and can be used locally without pesticide to reduce vegetable pollution, increase yield and increase benefit. In winter and spring stubble after pulling seedlings in July-September, the complete removal of vegetable seedling leaves, every 100 meters long shed (about 600
