控草栽培技术的研究
摘 要
花生,蔷薇目豆科一年生草本植物。花生从播种到开花需一个多月,花期长达两个多月。花单生或簇生于叶腋部,荚果。花生起源于南美洲热带、亚热带,约于十六世纪传入国内。
20世纪80年代起,地膜覆盖技术引进我国,对我国的农业生产方式和区域种植方式产生重大的影响。地膜覆盖技术因有蓄水、增温、保墒等功能,继而在我国被大面积推广应用,为我国的农业增效、粮食增产增收以及农民收入提高都做出了巨大贡献。通过实验验证,花生地膜覆盖栽培技术的增产效果在我国早已得到证实。随着地膜使用量增大、面积变广,且现用地膜较薄,极易破碎,未被回收的破碎地膜残留在土壤中,加重了我国环境的面源污染,使土壤理化性质发生改变,种子萌发出苗受到影响,农事操作也面临着种种困 *51今日免费论文网|www.51jrft.com +Q: ¥351916072¥
难。
为了响应国家号召及满足广大群众生产需要,越来越多功效不同的地膜随之出现。淋膜纸(秸秆膜)作为一类生物型可完全降解环保型地膜受到广泛关注。本实验预计通过数据统计比较分析,对淋膜纸覆盖栽培和塑料地膜覆盖栽培作以对比研究,探究淋膜纸是否可以代替农用塑料地膜,促进花生生长发育,达到防草、保墒的效果。
RESEARCH ON MULCH PAPER INSTEAD OF PLASTIC MULCH TO GROW PEANUTS AND CONTROL GRASS TECHNOLOGY
ABSTRACT
Peanut, annual herb of the rosaceae leguminous family. It takes more than a month from sowing to flowering, and the flowering period of peanuts is as long as two months. Flowers solitary or clustered in leaf axils, pods. Peanut originated in South America, tropical, subtropical, about the 16th century into the country.
Since the 1980s, plastic film mulching technology has been introduced into China, which has had a significant impact on Chinas agricultural production mode and regional planting mode. Mulching technology has been widely applied in China due to its functions of water storage, temperature increase and soil moisture preservation, which has contributed a lot to the increase of agricultural efficiency, grain production and income as well as farmers income. The effect of peanut mulch on increasing yield has been proved. With the use of plastic mulch increasing, the area is getting wider, and the plastic mulch used now is thinner and easily broken. The broken plastic mulch that has not been recovered remains in the soil, which aggravates the nonpoint source pollution of the environment in China, changes the physical and chemical properties of the soil, and affects the germination and emergence of seeds. The agricultural operation is also faced with various difficulties.
