冬枣是枣庄市薛城区近几年挖掘、开发的一个特晚熟地方名优鲜食枣树品种,据资料介绍,秋季和春季均可栽植。我们在多年实践中发现,秋栽一般死苗率为5%左右,严重的达15%以上,秋栽成活率明显低于春季栽植,其原因是秋季栽植树干冬季失水多,根系又处于休眠期难以补充,而春季土壤温度明显回升,植株根系已开始活动,栽植后土壤中的水份能及时运输到地上部,则易成活。我们试验观察表明,冬枣栽植最佳适期为4月上中旬(此时能达到根系活动的最低温度要求)。其栽植技术为:
Jujube is Zaozhuang City Xuecheng excavation in recent years, a special late-maturity place famous fresh edible jujube species, according to the introduction of information, autumn and spring can be planted. In many years of practice, we found that the average rate of dead seedlings in autumn planting was about 5% and the severity was up to 15%. The survival rate of autumn planting was significantly lower than that in spring. The reason was that in winter, Period is difficult to supplement, and the spring soil temperature rose significantly, plant roots have begun to move after planting soil moisture can be transported to the ground in time, it is easy to survive. Our experimental observations show that the optimum date for winter jujube planting in mid-April (at this time to achieve the minimum temperature of root activity requirements). Its planting technology is:
