辣椒是土传病害严重的作物,近年来,辣椒病害发生较为严重,致使农药使用量大大增加,严重影响了辣椒产量和品质,并对环境产生污染;此外由于冬季气温较低,影响辣椒根系的正常生长,而夏季高温高湿天气也对辣椒生长产生不良的影响,辣椒采用地膜加稻草覆盖栽培(简称覆盖栽培)技术,不仅能极大地改善根部环境条件,而且免除了中耕除草等作业,减少人工的投入,降低农事操作对根、茎、叶的损伤,减少病害的发生;保证冬季辣椒在温度较低的环境下,依然能正常生长,并且在高温的夏季通过稻草阻隔阳光对地膜的直射,有效地降低膜内表土的温度,减轻高温对根系造成的伤害。该技术适用于 Chili is a soil-borne diseases serious crop, in recent years, pepper disease occurred more serious, resulting in greatly increased use of pesticides, seriously affecting the yield and quality of peppers, and pollution of the environment; in addition due to the lower winter temperatures affect the root system of pepper Normal growth, while summer hot and humid weather also have an adverse effect on the growth of peppers, peppers using plastic film and straw covered cultivation (referred to as the cover cultivation) technology, not only can greatly improve the root environmental conditions, but also eliminates the cultivation and weeding and other operations to reduce Artificial input, reduce agricultural operations on the roots, stems and leaves of the damage and reduce the occurrence of diseases; ensure that the peppers in winter temperatures in the lower environment, still able to grow normally, and in the hot summer through the straw to block the direct sunlight on the film , Effectively reduce the surface temperature of the membrane, reduce the damage caused by high temperature on the root system. This technique works for
