精量穴播对玉米生长发育及经济效益的影响
Effect of Precision Sowing on Growth and Economic Benefit of Maize
摘要
Abstract
In order to promote popularization and application of precision sowing technology,taking Xianyu335 as material,through the compared experiment of precision sowing and conventional sowing,maize growth states were monitored and investigated.The effect of precision sowing on plant morphology,photosynthesis,agronomic traits,yield and economic benefit of maize were analyzed.The results showed that pricision sowing was more conductive to the indivdual and group′s growth of maize,enhanced maize′s resistence.Comparing with conventional sowing,precision sowing reduced seed quantity was 2.5 kg·hm.-2 and saved seed cost,sowing cost and thinning cost were 62.5 yuan·hm.-2,90 yuan·hm.-2 and 240 yuan·hm.-2,respectively.Precision sowing made maize yield increase by 699 kg·hm.-2,output value increase by 978.6 yuan·hm.-2 and net income increase by 1 371.1 yuan·hm.-2 which increased 26.71%.关键词
