探索了覆草保墒旱作的可行性及其配套的栽培技术。研究认为用覆盖 4 5 0g/m2 以上的稻、麦草取代覆膜旱作是可行的。覆草保墒旱作相应配套栽培技术 :改良、培肥土壤 ,增加土壤蓄保墒能力是前提 ;在选择抗 (耐 )旱性强的品种 (组合 )、培育素质好的旱育秧的基础上 ,增加栽插密度到 15穴 /m2 以上 ,每穴 2粒种子苗 ,施N18.75g/m2 ,N∶P∶K约 3∶1∶2 ,N肥底蘖肥后移、后期追肥比例增加到 30 %以上 ,可获较理想产量。
The feasibility of mulching with soil moisture and its cultivation techniques was explored. The research suggests that it is feasible to replace the dry film mulching with rice and wheat straw covering more than 450 g / m2. Covering the soil moisture for the corresponding supporting cultivation techniques: improving, fertilizing the soil, increase soil moisture conservation ability is the premise; in the selection of resistant (drought) strong varieties (combination), cultivate good quality dry seedling based on the increase Transplanting density to 15 holes / m2 or more, seedlings per hole 2 seedlings, applied N18.75g / m2, N: P: K about 3: 1: 2, N fertilizer tillering backward, late dressing proportion increased to 30 % Above, can be more ideal output.
