- 摘要:
- 为提高玉米单产、节水节本,以先玉335为材料,通过顶浆播种、精量播种、顶浆精量播种与常规播种对比试验,对土壤温度、含水率、玉米生长、产量及水分利用率各指标进行测定。结果表明:顶浆起垄结合垄上精量播种使土壤含水率增加,土壤温度比常规播种提高0.2~1.2 ℃,出苗率提高6.2%;玉米产量和水分利用率为顶浆精量播种>精量播种>顶浆播种>常规播种,和常规播种比,产量分别提高14.1%、11.7%和5.0%,水分利用率分别提高16.6%、12.2%和6.2%。顶浆起垄具有较明显的增温和保水效果,结合精量播种技术(顶浆精量播种),对提高玉米产量及水分利用率起到促进作用。
- Abstract:
- In order to increase maize yield,save water and reduce cost,Xianyu335 was taken as material,through the contrast test of conservation sowing,precision seeding,conservation with precision sowing and conventional sowing,the indexes of soil temperature,moisture content,maize growth,yield and water use efficiency were measured.The results showed that conservation sowing combined with precision seeding treatement could increase soil moisture content,soil temperature increased by 0.2~1.2 ℃,and germination rate increased by 6.2% compared with conventional sowing.Maize yield and water use efficiency showed conservation with precision seeding>precision sowing>conservation sowing > conventional sowing,compared with the conventional sowing,the yield increased by 14.1%,11.7% and 5.0%,and the water use efficiency increased by 16.6%,12.2% and 6.2% respectively.The effect of increasing temperature and water holding capacity of conservation sowing was obvious.Combined with precision sowing technology (conservation with precision sowing),the yield and water use efficiency of maize were improved.
