Plantation method for pseudo-ginseng under trees

Abstract

The invention relates to a plantation method for commercial crops and in particular relates to a plantation method under trees. The method comprises the following steps of dressing seeds, immersing seeds, selecting primary or secondary forest in an area of Northern latitude of 21 to 28 degrees and altitude of 1600 to 2300 as a plantation wood land, eliminating weeds and undershrubs for the plantation wood land, and conducting nursing work such as removing bend woods and remaining straight woods, removing weak but remaining strong woods, and eliminating weeds and pruning and cutting branches for the plantation wood land from February to April of each year from a time period ranging from two years after under-tree pseudo-ginseng seed fixed plantation or / and one year after annual seed bar fixed plantation to the harvest. Forest canopy density of the plantation area is maintained to be as high as 90%; under-tree pseudo-ginseng seeds processed in the second step is broadcast in the under-tree land or annual seed bars are fixedly planted; plant spacing distance is no less than 30cm x 30cm; and in the fifth step, the forest canopy density of the plantation area can is kept around 50 to 80%. Deficiencies of the prior art can be overcome; precious land occupation and damage by pseudo-ginseng plantation can be greatly reduced; damage to the environment by fertilizer chemicals and white pollutions can be reduced; and resource and energy consumption and loss can be reduced.

Description

technical field [0001] The invention relates to a method for planting economic crops, in particular to a method for planting under forests. Background technique [0002] Chinese patent application number 201410701361 discloses "a planting method of Panax notoginseng", which includes the following steps: soil preparation and base fertilizer application and furrowing; shed building and planting; field management; water and light management; topdressing; flower picking and weeding; pest control. The notoginseng planting method of the present invention reasonably arranges the field management mode according to the growth cycle of notoginseng, and provides sufficient nutrients for the growth of notoginseng under the condition of ensuring the normal growth of notoginseng. The planted notoginseng has good quality and high yield, and the yield of winter notoginseng can reach 150Kg; the planting cycle of notoginseng is short, and the yield is high and the quality is good.

AI Technical Summary

Problems solved by technology

[0005] At present, there are three main problems in the cultivation of Panax notoginseng. One is the excessive use of chemical fertilizers, which leads to the decline of the intrinsic quality of Panax notoginseng and the introduction of excessive heavy metals.

The second is to use a large amount of pesticides, resulting in excessive pesticide residues in Panax notoginseng

The third is continuous cropping obstacles, occupying a large amount of cultivated land

The land planted with Panax notoginseng cannot be cultivated continuously after one season (usually 3 years) of planting is completed, so that the cultivation of Panax notoginseng takes up a lot of valuable cultivated land

At the same time, because Panax notoginseng likes shade, the current planting mode must build shade sheds, which increases investment and costs on the one hand.

On the other hand, it affects the environment and increases energy consumption
