水稻传统栽培法限制了稻作进一步高产,笔者于一九七六年开始进行了八年的水稻栽培技术改革试验,把传统栽培改为旱作(或烂田和水源不足田的水作)整畦种稻(畦高五、六寸,宽七、八寸,畦距1.8尺左右,每畦种二行稻,株行距5×3(寸),采取无水层湿润灌溉),利用畦沟周年套养绿肥(春季红萍、夏秋季水浮莲或日本水仙,冬季黄花苜蓿或紫云英)结合免耕(晚稻和冬种免耕)、畦沟互换(第二年种早稻时进行)等措施,并以稻田养鱼代替人工中耕除草,称畦式通气高光效栽培法,达到高产、培肥、低耙的目的。分别在五个不同类型的
The traditional rice cultivation method has limited the further high yield of rice. The author started the eight-year rice cultivation technology reform experiment in 1976, replacing the traditional cultivation with dry farming (or water with bad fields and insufficient water resources) Rice paddy (five or six inches high, seven or eight inches wide, about 1.8 feet away from home, two rows of rice each species, spacing of 5 × 3 (inch), to take the anhydrous layer of wet irrigation) Annually planting green manure (Spring Red Hibiscus, Summer and Autumn Hibiscus or Japanese narcissus, winter alfalfa or asparagus) combined with no-tillage (late-rice and winter-type no-tillage) ) And other measures, and instead of artificial cultivation of rice paddies in the cultivation of weeds, called 畦 ventilation high light-efficiency cultivation method, to achieve high yield, fertilizer, low rake purpose. Respectively in five different types
