水稻超稀植栽培是经实验而形成的栽培技术新体系。一般可节本省工30％～40％,增产10％～15％以上,产投比大。主要采用分蘖力强的中早熟良种,肥床旱育,稀播培育带蘖壮秧,放宽行穴距,协调肥水管理,促进有效分蘖成穗,实现穗大、粒多、粒重,从而达到增产目的。 超稀植秧本田比率高,可达1:00,插1公顷田需芽种15～20公斤,省种25～30公斤。插秧省工省苗。旱育稀植30厘米×20厘米25穴,每穴3～4苗,需苗75～100株,而超稀植30厘米×20厘米I7穴,穴插3～4苗,需苗51～68株,若插30厘米×26.6厘米仅12.5穴,相对省苗1/2～1/3。按劳力日插秧470平方米计算,超稀植能插800～ Ultra-thin rice cultivation is the result of experiments and cultivation of new systems. The general section of the provincial labor 30% to 40%, an increase of 10% to 15%, production and investment ratio. The main use of strong early maturing tillering seedling, dry bed nursery, thinning sowing with tiller seedling, relax line spacing, coordinate fertilizer and water management, and promote effective tillering spike, to achieve spike, grain and grain weight, so as to achieve Increase production purposes. Ultra-thin seedling Honda high rate, up to 1:00, insert 1 hectare fields need to sprout 15 to 20 kg, the provincial species 25 to 30 kg. Provincial transplanting seedlings provincial workers. Drought nursery sparse planting 30 cm × 20 cm 25 holes, each hole 3 to 4 seedlings, seedlings required 75 to 100 strains, and ultra-thin planting 30 cm × 20 cm I7 points, plug 3 to 4 seedlings, need to seedlings 51 to 68 Strains, if inserted 30 cm × 26.6 cm only 12.5 holes, the relative provincial Miao 1/2 ~ 1/3. According to the labor day transplanting 470 square meters, ultra-rare planting 800 ~
