摘要/Abstract

摘要： 采用温室微区试验研究常规水作、裸地旱作、覆膜旱作和覆草旱作等土壤水分管理下水稻生长及其对水分的利用状况.结果表明,几种旱作水稻的需水量为349～473mm,常规水作水稻需水量为762.5mm.旱作水稻的水分籽粒和干物质生产效率为0.899～1.273g·kg^-1和1.655～2.321g·kg^-1之间,而相同条件下常规水作水稻水分的籽粒和干物质生产效率仅为0.766g·kg^-1和1.459g·kg^-1左右.覆草旱作水稻可以获得相当于常规水作水稻90%的经济产量.

Abstract: Subtle plot experiment was conducted to study the growth and water use status of rice cultivated on waterlogged soil and upland soil mulched with plastic film, semi decomposed wheat straw and nothing in Nanjing Agricultural University. The results showed that 349 to 473 mm of water were required by rice cultivated on upland soil mulched with film, straw or nothing, and 732.5 mm of water was required on waterlogged soil. The water productive efficiencies for rice grain and biomass were between0.899 to 1.273, and 1.655 to 2.321 g穔g^-1, respectively in upland cultivation, while 0.766 and 1.459 g穔g^-1 in waterlogged cultivation. Rice cultivated on upland soil mulched with semi decomposed straw achieved 90% or more economic yield on waterlogged soil.
