保水剂在黄土高原旱地农业应用效果的研究
- Title:
- Effects of Application of Water-holding Agent on Arid Areas in Loess Plateau

- 摘要:
- 保水剂是现代旱作农业中一项有效措施.在旱作春玉米上施用保水剂，增加产量1%～33.47%，在大豆生产上增产3.9%～3.1%，产量随保水剂用量增加而增加，但保水剂施用在土壤中的增产效益较低.用保水剂处理种子，成苗率增加，增产效果显著，是目前生产水平下是一项有效的增产措施.
- Abstract:
- Application of water-holding agent is an effective measure of drought prevention and resistance in modern dry-land farming agriculture.Application of it on corn were studied,its output can increase 12%～33.47%,3.9%～23.1% on soybean,the output increase with the quantity of it.But the rate of application of it in soil is low.The treatment of seed soaking or the transplant of root soaking could greatly increased crop yields,the succeeded rate of seeding increased,the effect of crop yields and economic benefit was marked,it ought to be spread in arid zone.
