Method for preparing transplanting matrix for blueberry pot seedlings

Abstract

The invention discloses a method for preparing a transplanting matrix for blueberry pot seedlings. The method comprises the following steps: (1) surveying the soil pH of a seedling raising field; (2) deeply plowing the seedling raising field by the depth of 30-40cm, and removing foreign bodies such as stone; (3) applying sulfur powder to the seedling raising field so as to adjust the soil pH value to an appropriate pH value, meanwhile, broadcasting dazomet to the seedling raising field, carrying out uniform stirring, and then, covering the seedling raising field with films for fumigation; (4) adding peat and fermented sawdust which are in a certain ratio into soil, so as to improve the soil and increase the organic matter content of the soil; and (5) carrying out uniform stirring mechanically, so as to obtain a mixture for later use. According to the method, the dazomet is adopted to fumigate the soil, so that the disease damage caused by meloidogyne spp. is avoided, and the cost for treating weeds is reduced; meanwhile, the soil pH value is adjusted by using the sulfur powder, and a synergetic effect of the dazomet and the sulfur is generated, so as to obtain a better effect; and the fermented sawdust and the peat are added and interact with the sulfur, so that the structural formation of soil aggregates is promoted, the organic matter content is increased, the quality of the soil is improved, and the success rate of blueberry seedling raising is greatly increased.

Description

technical field [0001] The invention relates to the technical field of blueberry seedling planting, in particular to a preparation method of a blueberry seedling transplanting matrix. Background technique [0002] Blueberry belongs to the genus Vaccinium of Rhododendronaceae. The fruit is rich in anthocyanins and other nutrients. As the third generation of emerging fruits in my country, the large-scale cultivation of blueberry is in a period of rapid development. Blueberry cultivation has very strict requirements on the pH value of the soil, which is one of the most important factors that need to be investigated in blueberry cultivation. The suitable pH is between 4.5 and 5.5. Simply using sulfur to adjust the pH will take effect slowly, and it is easy to over-adjust, resulting in The pH is too low. Compared with foreign countries with better development of blueberries, the organic matter content of soil in my country is generally 1%-3%, while the organic matter content of ...

Compared with foreign countries with better development of blueberries, the organic matter content of soil in my country is generally 1%-3%, while the organic matter content of blueberries is generally required to be above 6%. At the same time, affected by the long-term application of large amounts of chemical fertilizers, the soil aggregate structure is poor , serious hardening, and prone to soil-borne diseases and insect pests, the growth of seedlings is greatly affected
