The optimal sowing period and the growth of summer maize are often affected by the high temperature and less rainfall in the early Summer.
初夏高温少雨，常影响夏玉米适时播种和苗期生长。The main experimental results were as follows: 1. There was a significant difference in growth for seeding stage among poplar clones.
主要研究结果如下：1。杨树各无性系苗期生长性状均达到极显著水平。Tomatoes in seedling stage have no correlation with those in blooming and setting stage on low light tolerance.
番茄苗期和开花坐果期各自的耐弱光性并不相关。Severe water deficit at seedling stage and wadding stage , medium water deficit at buds and bolls stage can be propitious to cotton yield.
苗期和吐絮期重度水分亏缺、蕾铃期中度水分亏缺均有利于棉花产量的形成。The invention has favorable effects of controlling the insect harm in a seedling period and improving the seedling maintained rate.
本发明经大豆田间药效小区试验，对于防治苗期害虫危害提高保苗率具有很好的效果。Inoculation with VA mycorrhizal fungi significantly increased mycorrhizal infection and enhanced seedling growth.
苗期接种va菌根菌可提高菌根感染率，促进苗木生长。The results of solution cultivation experiment indicated that silicate improved the growth of sugarcane seedling under drought condition.
水培试验的结果表明，施硅能够改善甘蔗苗期在干旱条件下的生长。Have strict specifications of its culture medium preparation, sowing and seeding, management of growing and seeding and other aspects.
其营养基配制、播种育苗、苗期管理和栽培技术等方面都有严格的要求。Germination and early seedling growth are very important for maize forward development and final production.
玉米在萌发期和苗期的耐旱性与最终收获产量有很大相关性。
