Efficient cultivation method for southern highbush blueberries in protected area

Abstract

The invention discloses an efficient cultivation method for southern highbush blueberries in a protected area. The invention relates to the technical field of agricultural cultivation. Blueberry production mainly has the problem of slow growth, and blueberries can enter a high-yield period after being planted for more than two years. By means of the method, the high-yield period can be achieved within one year, and rapid and efficient cultivation is realized. According to the main technical scheme, the method comprises the following steps: S1, carrying out medium potting, and carrying out drip irrigation and spraying by an 5/10000 to 1/1000 aqueous solution of ammonium sulfate and the like as required every day, wherein the pH value of the aqueous solution is adjusted to be about 5.0 by citric acid and the like; S2, applying a high-quality bio-organic fertilizer, medium trace element fertilizer or water-soluble compound fertilizer solution as required in the seventh day after planting; and S3, controlling growth of the blueberries from vigorous growth to cold weather, so as to promote nutrient accumulation, flower bud formation and relatively concentrated flower formation. The method is suitable for planting in the southern highbush blueberry protected land in an area in which the temperature is higher than zero DEG C in winter, the low temperature meets the cold requirement of the variety, and the temperature can be controlled by spraying or shading when being higher than 38 DEG C in summer .

Description

technical field [0001] The invention relates to the technical field of high-efficiency cultivation of blueberries, in particular to a method for high-efficiency cultivation of blueberries in protected southern highbush. Background technique [0002] Blueberry, Rhododendron Vaccinium is a perennial shrub. It is native to Northeast my country, Europe and North America. Blueberry fruit is rich in anthocyanins. It is popular all over the world because of its high health value. It is the World Food and Agriculture Organization One of the five recommended healthy fruits. However, as the earliest country to cultivate blueberries, the United States has a cultivation history of less than a hundred years. In particular, the history of southern highbush blueberry cultivation is even shorter. Therefore, the efficient cultivation of southern highbush blueberry is an urgent problem to be solved in production. [0003] Because the elongation range of blueberry roots in the soil is relati...

Problems solved by technology

[0004] In recent years, the cultivation of southern highbush blueberries has achieved good results in the protected underground of Yunnan and other places in my country by using substrate bag culture and integrated water and fertilizer. However, the direct production cost of planting is still high, and the growth rate and planting first Annual output needs to be increased
