当前小麦田间调查时没有把播种深度作为主要调查指标,随着耕作制度的改变,旋耕机成为当前小麦栽培上的主要整地工具后,导致小麦播种深度过深的现象屡见不鲜,因此造成出苗受阻、生长不良和病虫害发生严重等情况连年发生,所以播种深度已成为衡量小麦播种基础、苗期长势和后期发展趋势的重要数据之一。一、列为调查指标的分析上蔡县是一个农业生产大县,耕地面积11.0万公顷,小麦常年种植面积9.3万公顷,近几年采用旋耕机
In the current wheat field survey, the sowing depth was not taken as the main survey index. With the change of tillage system, rotary tillage machine became the main land preparation tool for wheat cultivation. As a result, the sowing depth of wheat was not uncommon, Poor growth and serious occurrence of pests and diseases occur year after year, so planting depth has become a measure of wheat planting base, seedling growth and the late trend of one of the important data. First, the analysis as an indicator of investigation Shangcai County is an agricultural production county, arable land area of 110,000 hectares, 93,000 hectares of wheat planted year round, in recent years using rotary tiller
