一、试验目的和要求为适应农村生产发展新形势,探讨水稻高产稳产低成本的有效途径,改革玉林地区传统的以“前重、中控、后补法”(下简称前重法)为核心的水稻高产栽培,我们于1980年进行预试,81年玉林地区科委安排小试,82年自治区科委下达试验项目正式开始本课题的研究。试验要求探索在一类稻田中单造亩产超千斤,斤谷成本(种子、肥料、植保、水费等)三分以下,个别造减产少于10%;亩用 I. Objectives and Requirements of Experiments In order to adapt to the new situation of rural production and development, explore effective ways for high yield, low cost and stable yield of rice, and to reform the tradition of Yulin area with the core of “pre-heavy, intermediate control and post-supplementation” Of the high-yielding cultivation of rice, we conducted a pre-test in 1980, 81 Yulin Prefecture Science and Technology Commission to arrange a small test, autonomous regions and municipal science Commission issued a pilot project in 82 officially started the study of this topic. The test requires exploration to find that in a type of paddy field, the per-mu yield of a single mu is over one third, the cost of catches and grasses under one third of the cost (seed, fertilizer, plant protection, water fee, etc.)
