1984—1986年湖南省粮油生产局组织10个地、市的15个县农业局和4个省、地、县科研单位进行花生——稻耕作制度研究。主要探讨花生在稻田栽培条件下的适宜品种、密度、施肥量和施肥法、地膜覆盖栽培增产效应、一播全苗技术,以及高产栽培的配套技术和轮作的生态效益等。试验分别采用随机区组设计、裂区设计、多因子正交试验,大区对比试验以及田间调查的办法进行。 一、研究结果与分析 1、筛选出适合花生——稻耕作制的花生和晚稻品种。花生品种有新城早、海花一号和粤油551—116。这些品种,一是丰产性好。新城早1985年平均单产为312.2公斤,1986年为339.4公斤,居参试品种
1984-1986 Hunan Bureau of Grain and Oil Production organized peasants and paddy systems in 15 prefectural counties in 10 cities and cities and 4 provincial, prefectural, and county scientific research units. This paper mainly discusses the suitable varieties, density, fertilizer amount and fertilization method of peanut under paddy field cultivation, yield increasing effect of plastic film mulching cultivation, seedling planting technology, and supporting techniques of high yielding cultivation and ecological benefits of rotation. The experiments were conducted using random block design, split zone design, multi-factor orthogonal test, large area contrast test and field survey. First, the research results and analysis 1, selected for peanut - paddy farming system for peanut and late rice varieties. There are varieties of peanut Metro Metro, the first flower and Guangdong Oil 551-116. These varieties, first, high yield good. Metro as early as 1985 average yield of 312.2 kg, 339.4 kg in 1986, ranking the test varieties
