精量点播是精准农业中精准播种技术的要求,实现精量播种可使苗匀、苗齐、苗壮,不需要间、定苗作业;可节省大量种子,有利于种子良种化、精准化。精量播种的田间植株分布均匀、苗壮,利于单株发育,其增产效果明显。一、棉花精量播种条件1.土地准备备耕是一播全苗的前提和基础,待播棉田要有足够的底墒水,秋翻前务必施足农家肥,并适当控制氮肥,增施磷肥。播前用联合整地机合墒耙地,边耙边进行化学除草工作,最终达到地平土碎、上虚下
Precision on-demand precision agriculture is the precision of sowing technology requirements, to achieve precision sowing Miao Miao, Miao Qi, Miao Zhuang, do not need between the Dingmiao operation; can save a lot of seeds, is conducive to the seeds of seed, precision. Fine sowing field plants evenly distributed, Miao Zhuang, which is conducive to the development of plants, the yield was significantly improved. First, the cotton sowing precision conditions 1. Land preparation Preparation is a prerequisite for planting a full seedlings and the foundation, to be sowing cotton fields have enough moisture at the end of autumn Qiufanyuan farmers must be sufficient, and proper control of nitrogen fertilizer, phosphate fertilizer. Before sowing with a combination of soil preparation machines rake harrow, rake while carrying out chemical weeding work, and ultimately reach the ground broken soil, on the virtual
