黄连木育苗技术试验

The experiment of raising seedlings of Pistacia chinensis

对黄连木采用不同种子处理、贮藏方法、播种期、播后苗床覆盖、苗木遮荫、育苗密度、土壤追肥等措施进行育苗试验。结果表明：用草木灰或碱水对种子脱蜡去脂并进行混沙或黄心土贮藏，播种后及时覆盖稻谷皮或地膜均有利于提高种子发芽率；冬播比春播更有利于种子萌发和提高苗木生长量；全光育苗、保持60株·m^-2密度、土壤追施速效复合肥均是提高苗木生长量和质量的有效技术措施。应用有序样本聚类分析法将黄连木1年生播种苗高生长过程划分为4个时期：出苗期（3月4日～4月10日）洼长初期（4月11日～6月30日）、速生期（7月1日～9月10日）、苗木硬化期（9月11日～10月10日）。

This experiment studied on the seed treatment and storage methods, sowing peroid, seedbed cover, seedling shading, reasonable density, fertilizing after sowing and so on. The results indicates it could enhance the seed germination rate to use plant ash and alkaline water to dewax the seeds, then to mix with sands or core yellow soil for storage, and to use paddy hull or plastic paper to cover the seedbed. The germination rate and the seedling growth increment were enhanced while sowing in Winter than in Spring. It could enhance the seedling growth increment and quality that full sunlight growing, keeping 60 individuals· m^-2 and fertilizing fast-release compound fertilizer. According to the cluster analysis method, the growth procesaes were classified as 4 stages： emergencing stage （Mar 4--Apr 10）, initial growing stage （Apri 11-Jun 30）, fast growing stage （Jul 1-Sep 10）, and hardening stage （Sep 11-Oct 10）.
