北方贫水区水稻覆膜技术是承德县农业局经多年研究获得成功的一项水稻高产栽培新技术。该项技术适宜北方贫水区推广应用,其特点是节水、省工、费用低。1999年通过国家科技部北方贫水区水稻覆膜直播技术专题项目的验收。由承德县农业局编写的水稻覆膜直播栽培技术规程已被列为承德市地方标准。该技术的成功为北方贫水区发展节水农业创出了一条新路。覆膜直播水稻配套栽培技术要点如下: 一、精细整地。根据土壤平整程度做畦,每畦面积100～600平方米,每隔1—2排畦设一条灌水渠,然后进行耕翻、灭茬,
Rice paddy film technology in the northern water-deficient area is a high-yielding cultivation technology of rice that Chengde County Bureau of Agriculture succeeded for many years. The technology is suitable for popularization and application of the northern impoverished area, which is characterized by water saving, labor saving and low cost. In 1999 through the Ministry of Science and Technology in northern water-deficient areas of rice film direct seeding technology project acceptance. Chengde County Bureau of Agriculture prepared by direct seeding rice cultivation technical regulations have been classified as local standards in Chengde. The success of this technology has created a new path for the development of water-saving agriculture in water-poor northern areas. Film-coated rice cultivation techniques supporting points are as follows: First, fine preparation. According to the degree of soil formation 畦 每, each 畦 area of 100 to 600 square meters, every 1-2 rows 畦 set up a irrigation canal, and then plowing, stubble,
