经过多年的育苗实践,落叶松育苗技术已为大多数群众基本掌握,但由于落叶松种子粒小,幼苗嫩弱,极易遭受恶劣环境影响,因此保苗率不高,育苗不成苗现象在一些单位屡屡出现。特别是一些社(队)办苗圃,春播后,苗木出土尚好,每平方米一千多株苗,到后来只剩下二、三百株,甚至出现“光板床”,既浪费了种子、浪费了劳力,又挫伤了群众育苗的积极性。落叶松育苗的重要环节,首先要解决保苗问题,其次是提高苗木质量。其中保苗是基础,优质是目的。如何实现落叶松育苗数量和质量的统一呢?本文着重谈这个问题。一、加强土壤和肥分管理是保苗优质的基础土是苗木生长的基础,苗木的根系是在
After years of nursery practice, larch nursery technology has been mastered for most people, but due to small larch seedlings, tender young seedlings vulnerable to harsh environments, so the seedling rate is not high, nursery seedling phenomenon in some units Repeatedly appear. In particular, some clubs run nurseries. After the spring sowing, the nursery stock was still unearthed well, with more than 1,000 seedlings per square meter. Only two or three hundred plants were left and only the “light board bed” was left, which wastes seeds and wastes Labor, but also dampened the enthusiasm of the people raising seedlings. Larch seedling an important part of the first to solve the problem of seedlings, followed by raising seedling quality. One seedling is the foundation, high-quality is the purpose. How to achieve the unity of quantity and quality of larch nursery? This article focuses on this issue. First, to strengthen soil and fertilizer management is the basis for high quality nursery stock seedlings is the basis for the growth of seedlings in the root system is
