该文主要结合东辽县玉米种植情况,就玉米高产栽培技术进行了分析,希望通过这次研究对提高玉米生产质量有所助益.

大豆就是我们常说的黄豆,原产于我国,在我国各地均有种植,属于豆科大豆属,1a生草本作物,茎粗壮,直立,高度一般最矮不低于30cm,最高不超过1m,是我国重要的豆类之一,也是重要的小杂粮.伴随着人们生活水平的提高,越来越多的人开始注重养生,而大豆无论是作为重要的豆类和杂粮,还是作为大豆饮品以及饮食上的必须品都深受人们喜爱,人们也对大豆品质提出了新的要求.本文总结了大豆高产种植技术要点,为广大农户提供参考.

Agrobacterium-mediated transformation was performed in the peanut variet‘y Silihong’using hypocotyl as explants.After co-culture,bacteria restraining and selection,sixty-seven resistant regenerated plants were obtained on the medium with 0.8mg/L Basta.Five PCR-positive plants were tested by Quick-Strip Kit and at least two of them showed positive.The results showed that this protocol was an easy and high efficient,and will provide a practical method for the further genetic improvement of peanut.

The experiment of plasma treatment on peanut was carried out in the paper.The results showed that the number of root,average length of root and falling needle rate of peanut were increased by plasma treatment.While plant heights during seedling stage,flowering stage and falling needle stage were decreased.Peanut yield increase by 166.0-608.0 kg/hm2 compared with treatment 7,which was 4.1-13.7%.Economic output increased by 832.0-3 042.0 yuan/hm2.In treatment 2,yield increased by 608.0 kg/hm2,which was 13.7%,and economic output increased by 3 042.0 yuan/hm2.The result showed that treatment 2 was optimal treatment with the most yield increase and economic output.

吉林省东辽县2007～2009年连续3年在高、中、低3类地块上进行了玉米多点次"3414"田间试验,对土壤养分和试验结果进行了总结分析,得出玉米土壤养分丰缺指标和玉米施肥指标。

吉林省东辽县对玉米施用"大壮高效叶面肥"的施用量进行了研究.结果表明:小区试验"大壮高效叶面肥"的适宜用量为每次1 000 g/hm2.

对吉林省东辽县施用高塔造粒复合肥的适宜用量进行了研究.结果表明:小区试验百利丰盛牌高塔造粒复合肥的适宜施肥量为500～600 kg/hm2.同时提出了高塔造粒复合肥在生产实践中的配套技术措施.

2007年在对吉林东辽县土壤养分状况进行检测分析基础上,在有代表性中等肥力地块上,对化肥用量减少20%的情况下,增施不同数量有机肥,玉米产量明显增加.建议适量增施农肥,合理施用化肥.
