A method for improving soil quality and yield of wokan orchard in sloping farmland

Abstract

The invention relates to the technical field of fruit tree cultivation, and specifically discloses a method for improving soil quality and yield of fertile citrus orchards on sloping farmland. Rake the land and level it again; plant disease-free citrus seedlings from March to April; during the young age of the fertile citrus trees, plant grasses between the fertile citrus trees from September to October, and plant the stems of the grasses from February to March of the following year. The leaves are sprinkled on the ground or in the ditch, and soil conditioners are applied at the same time, and then the land is leveled by plowing and raking; from April to May, legumes are planted among the citrus trees, and the beans are harvested from August to September of the same year, and harvested on the spot The remainder is cut short and ploughed into the soil for green manure. The method of the invention can increase the content of organic matter in the soil, enhance the permeability and aeration of the soil, relieve the acidification of the soil, increase the adsorption of nutrients in the soil, reduce the loss of nutrients, comprehensively improve the soil quality, and improve the root growth environment, so that the fertile The yield of mandarin was increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for improving the soil quality and the yield of fertile citrus orchards on sloping farmland. Background technique [0002] Wokan is a perennial evergreen fruit tree of the Rutaceae citrus genus. It is a hybrid of "Temple" orange and "Dancy" red orange, belonging to the broad-skinned citrus type. "Wogan" has the characteristics of strong tree vigor, beautiful fruit appearance, good quality, late maturity, early fruiting and high yield, long fruit harvesting period, wide adaptability and strong disease resistance. Not only that, the sugar content of this citrus It is also much higher than ordinary citrus, with many advantages such as delicious and refreshing taste, easy peeling and so on. With the development of the economy, people's pursuit of the taste and health of fruit has gradually increased. The various advantages of wo citrus have made t...

Problems solved by technology

[0003] At present, in order to improve the growth of citrus citrus, farmers blindly apply a large amount of chemical fertilizers, ignoring the use of organic fertilizers and soil improvement and cultivation, resulting in poor soil structure, soil compaction, deterioration of soil physical and chemical properties, serious soil acidification, and a significant decline in fertility. There are problems such as unreasonable fertilization methods and fertilization periods, which will affect the growth of citrus citrus, mainly in the following aspects: the lack of soil organic matter affects the healthy environment for root growth, and the promotion of new roots is less, resulting in a vicious cycle. Yellowing; soil acidification, the harm of soil acidification is mainly manifested in the serious loss of base ions, the decline of cation exchange capacity, the loss of nutrients, the activation of heavy metal cations, etc., resulting in the continuous deterioration and decline of land quality, affecting the root growth environment of fruit trees, weakening The absorption ability of the root system to the base fertilizer is reduced, resulting in nutrient deficiency yellowing; the soil is compacted and the permeability is poor, which causes the root system to rot and cause yellowing

The yellowing of the citrus will lead to a decline in the quality and yield of the citrus, reducing the economic benefits of the farmers
