陆川县三年多来大面积推广抛秧技术,现介绍亩产超过550公斤的大田管理办法于下:一、大田作业。施足基肥,亩施碳铵、磷肥各25公斤。大田要求整平耙细,田面糊烂,并清除田间杂草。小田块田边要刮低成沟,大田块除四边开沟外,中间也要分厢,工作行要刮低成沟,以利排水晒田。二、抛秧操作。中等肥力田块亩抛2万穴,瘦田可适当增至2.3万穴,肥田减至1.8万穴。操作前先数一下秧盘空穴,根据空穴率确定秧苗盘数,抛秧时要注意把串根的秧苗分开,先用70%左右的秧苗抛撒,布满全
Luchuan County in more than three years to promote large-scale throwing seedling technology, are introduced more than 550 kilograms per mu field management approach in the next: First, the field operations. Shizujifei, Mushi ammonium bicarbonate, phosphate each 25 kilograms. Field requires leveling rake thin, Tian Mulan, and clear the field weeds. Oda block edge to scraping into a ditch, Oda block in addition to the four sides ditching, but also the middle of the points, the work line should be scraped into the ditch, to facilitate drainage Sha Tin. Second, throwing transplanting operation. Medium fertility plots acres throw 20,000 points, lean field may be increased to 23,000 points, reduced to 1.8 million fat fields. Count a few holes before operating seedlings, according to the hole rate to determine the number of seedlings, throwing seedlings should pay attention to the root of the seedlings separated from the first with about 70% of the seedlings throwing, full
