山地苹果园穴贮肥水技术研究

Technique of Storing Water & Fertilizer in Hollow on Apple Orchard on the Hill

为了解决洮南市北部半山区在山地发展苹果树水资源缺乏的矛盾,以洮南市北部半山区果树试验场20年生的123苹果树为试材,研究山地苹果园采用穴贮肥水技术措施对苹果树生长发育的影响。结果表明:穴贮肥水技术可提高新梢生长量21.6%,提高叶绿素含量14.7%;平均单果质量比清耕提高22.3%。特等果率较对照提高27.3%。穴贮肥水可使苹果树增产2161.64 kg.hm-2,纯增收1689.07元.hm-2。

In order to solve conflict of lacking water in the apple orchard on hill, by taking measures of storing water and fertilizer in the hollow , the effect of growth ＆ development of 20-year-old 123 apple tree in apple tree experiment site in northern semimountainous area in Taonan city were studied, It is tested that the technique of storing water ＆ fertilizer in the hollow can increase the growth of young sprout ＆ the content of chlorophyll by 21.6%, 14.7% ;the mean single fruit quality is 22.3% higher than that of weed clearing; top-grade fruit ratio is 27.3% higher than that of CK. Apple tree can be increased by 2 161.64 kg .hm^-2 by technique of storing water ＆ fertilizer; net-increase income is 1 689.07 Yuan .hm^-2.
