近些年来,随着反季节蔬菜种植技术的不断推广普及,茄果类蔬菜种植季节相应延长,而与其共生的杂草也随之伴生,若稍加疏忽,就会产生草荒并危及茄果类蔬菜的正常生长发育。由于茄果类蔬菜生育时间相应延长,为了提高化学除草的效果,除草时间应分段进行。在操作技术上应注意以下几点。一、明确除草时段根据多年实践经验,茄果类的蔬菜分为播前除草、栽前除草和栽后除草几个阶段进行,只有分段实施才能比较彻底干净地消除杂草。二、严格选用除草剂为了准确地消灭杂草,避免伤及菜苗、不同生育阶段应选用不同的除草剂。 1、茄果类蔬菜播种之前可选用25%胺草磷每亩200毫升,也可用70%赛
In recent years, with the continuous popularization of anti-season vegetable planting techniques, solanaceous vegetables correspondingly extend the season of planting, and its accompanying symbiotic weeds also accompanied, if slightly negligent, it will produce grassland waste and endanger the eggplant The normal growth and development of vegetables. Due to the corresponding growth of eggplant vegetables, in order to improve the effect of chemical weeding, weeding time should be carried out in stages. In the operation of technology should pay attention to the following points. First, a clear weeding time According to many years of practical experience, vegetables are divided into pre-greenery weeding, planting weeds and transplanting weeding several stages, only the implementation of fragmentation can more thoroughly and cleanly eliminate weeds. Second, the strict selection of herbicides In order to eliminate weeds accurately, to avoid injury vegetable seedlings, different stages of growth should use different herbicides. 1, solanaceous vegetables can be used before sowing 25% Amomum 200 mu per acre, also available 70% race
