通常植物的生长受气温、日照、肥料、土壤水分及空气流通性的影响较大,但有关影响根生长因素的报道较少。前报中以根类生药桔梗为例,对影响根生长的因子进行了分析,结果表明:利用土壤调节剂(PX)可促进土壤团粒结构的形成,利用地膜覆盖可改变土壤物理条件,如使土壤温度上升,使土壤保持理想结构等从而增加根的产量。本文探讨了在各种土壤中通气与产量的关系。 1 实验部分 1.1 实验地点同前报。 1.2 实验材料桔梗种子为当地贮存种。肥料为市售品。施肥量为硫酸钾0.02kg/m~2,
Generally, the growth of plants is greatly affected by temperature, sunshine, fertilizer, soil moisture and air circulation, but there are few reports on the factors affecting root growth. In the former report, root growth hormone (Campanulaceae) was used as an example to analyze the factors influencing root growth. The results showed that the use of soil conditioner (PX) can promote the formation of soil aggregate structure and the use of mulching can change the physical conditions of soil. Soil temperature increases, the soil structure to maintain the ideal so as to increase the yield of the root. This article explored the relationship between aeration and yield in various soils. 1 experimental part 1.1 experimental site with the previous report. 1.2 Experimental material Campanulaceae seeds for the local storage species. Fertilizer for the commercial products. Fertilizer amount of potassium sulfate 0.02kg / m ~ 2,
