摘要
对果树越冬进行了不同覆盖方法的比较。结果表明:双层覆盖可以抵御-40℃的极端寒冷天气,果农不必担心冻害问题;而单层覆盖最低温度达-25℃的临界值,并且指出单层覆盖下增加覆草厚度对提高温度没有意义,结果与单层覆盖相同。双层覆盖的果实产量和品质都与传统土埋没有差异。双层覆盖每667m2的费用是传统土埋方法的46.3%,节省2 364元,节本增效。双层覆盖简便易行又能清洁生产,增强了果农种植果树的积极性。这种简单且成本低廉的双层覆盖技术,对促进林果产业可持续发展有重要意义。
It is concluded that using double coverage hibernalisation technology could resist --40℃ ,however, monolayer coverage hibernalisation technology was much more dangerous with the critical value of --25℃, furthermore, increasing the hayes thickness in monolayer coverage hibernalisation technology had no significance through comparing different coverage hibernalisation technology of fruit tree. The fruit production and quality under the double coverage hibernalisation technology had no difference with traditional earth covering. The cost per acreage of double coverage was 46.3% of traditional earth covering, saving 2 364 yuan per acreage. The double coverage hibernalisation technology of fruit tree could enhance the activity of raising fruit tree for farmers because of the convenience. The double coverage hibernalisation technology with low cost and convenience had important significance for promoting the implantation of fruit trees.
