经验证明,棉田进行封根培土能抗旱、防涝、防风、保肥、通风和除去杂草、便利灌溉,对棉花增产的作用很大。专区农场于1954年创造了一个培土工具,效果很大,如用人工进行封根培土,一人一天只能做1.5—2亩,费工又累人,且伤棉株花蕾嫩枝,同时往往作得不徹底,而创制的培土器,一个人同一头牲畜一天即可把14.5亩棉花的封根培士工作做完.提高效率7--8倍,操做标准不比人工差,而且不损伤棉株。 Experience has shown that cotton mulching and soil sealing can resist drought, prevent waterlogging, prevent wind, keep fertilizer, ventilate and remove weeds, facilitate irrigation and greatly increase the yield of cotton. Area Farm in 1954 to create a tool for earth-moulting, the effect is great, such as using artificial sealing soil, one person can only do 1.5-2 acres per day, labor and tiring, and hurt cotton buds branches, and often make Not complete, and the creation of the earth-cultivating device, a person with the same animal a day can be 14.5 acres of cotton seal root Pei work done to improve the efficiency of 7 - 8 times, operating standards than artificial poor, and does not damage the cotton Strain.
