花生单粒精播增产机理研究进展
Research Progress on Yield-Increasing Mechanism of Peanut by Single Seed Sowing
摘要
Abstract
The contradiction between the supply and demand of edible vegetable oils in China is promi-nent,and the rate of self-sufficiency is less than 35%.Peanut owns the prominent position in ensuring the edible oil safety and food security.In recent years,the total yield of peanut had not increased largely,mean-while,the competition with grain and cotton for land should be avoided.Therefore,the emphasis of increasing peanut yield should be increasing the yield per unit area.The contradiction between group and individual of double seed hole sowing was outstanding under high yield conditions,and the population quality declined, therefore,the pod yield was difficult to be further improved.The single seed sowing pattern made peanut plants distributed evenly and reduced the competition among plants.The contradiction between group and indi-vidual was also relieved,so the production potential of single plant could be fully played.The single seed so-wing pattern had realized a new way for increasing the economic coefficient with the basically stable total bio-mass.The effects of single seed sowing on individual development characters,such as plant traits,physiologi-cal characteristics,nutrient absorption and utilization,and population structure characters like population uni-formity,population photosynthesis,source and sink relationship and yield composition,were systematically ex-pounded to announce its yield-increasing mechanism.The high yield cultivation technology system was estab- lished with the key technology of single seed sowing and the supporting technology of fertilizing and manage-ment,which had promoted the level of peanut yield per unit area and had a wide application prospect.关键词
