我所1975—1978年棉花采用直育创高产的方法,取得良好效果,并积累了一些经验。初步认为这种方法对突破三百斤皮棉是大有希望的。棉花直育就是利用塑料薄膜在棉田直接覆盖播种棉行育苗不再移栽。它是棉花育苗移栽技术的提高和发展。群众说它是棉花地里的小温室。“直育”可以增加积温,有效地提早棉花生育期,克服移栽棉花伤根、缓苗期长、费劳力等缺点,有利于促使棉花早发,是夺取早熟高产的一项有效措施。
From 1975 to 1978, our cotton method of using direct fertility to create high yields achieved good results and accumulated some experience. Initially that this method of breaking three hundred pounds of lint is promising. Cotton is a direct use of cotton plastic film in cotton fields covered cotton sowing seedlings no longer transplanted. It is cotton seedling transplanting technology improvement and development. The masses say it is a small greenhouse in cotton fields. “Straight-through” can increase accumulated temperature, effectively increase the growth period of cotton and overcome the disadvantages of transplanted cotton roots, slow seedling period and laborious labor. It is good for cotton to get premature, which is an effective measure to seize high yield of precocious puberty.
