水稻半旱式耕作法(又称垄畦栽培法,即起垄栽稻)。稻田做成垄沟相间式样,垄畦面宽23cm,垄高20—23cm,沟面宽30cm。垄畦上栽稻两行,株距13cm,垄上行距20cm,垄与垄之间稻株行距33cm,禾苗分蘖后,垄畦面保持湿润,沟内蓄水。使稻田既有水,又通气,形成不利于病菌侵染衍繁,而有利于植株生长发育的田间小气候和生态环境,以达到抑制、减轻病害,促进增产。 近几年来,我县在一晚田中大面积推广半旱式耕作法综合防治纹枯病,收到了显著
Semi-arid cultivation method of rice (also known as ridge cultivation method, that is ridging of rice). Ditch paddy made of white and white pattern, ridge ridge width 23cm, ridge height 20-23cm, groove width 30cm. Ridge on the two rows of rice, spacing 13cm, ridge spacing 20cm, ridge and ridge between rows of rice spacing 33cm, tiller tillering, Ridge remain moist, ditch within the reservoir. So that both paddy water, and ventilation, the formation is not conducive to pathogenic bacteria infestation, but conducive to plant growth and development of the microclimate and ecological environment in order to achieve inhibition, reduce disease and promote production. In recent years, our county in a late-night large-scale popularization of semi-dry cultivation method integrated control of sheath blight, received a significant
