Liu Huai-wei · 2000
In Junan county, the yield of summer sowing peanut (Arachis hypogaea L.) under plastic-film-covered cultivation was high and stable in successive years. Condition plastic-film-covered the physico chemical properties of soil was improved, the drought-resistant and waterlog-enduring ability of soil increased, the effective accumulated temperature increased, The accumulation of photosynthetic product, pod number, plump-pod rate and economic coefficient were increased, The necessary technology included selecting soil in good condition of fertility and water, a compound for applying fertilizer, rational close planting, sowing seeds with crop for rotation, covering plastic film in good time, sparing plant growth regulators, preventing and controlling the harm diseases and pests and preventing premature senility.
