Single-grain intensive-sowing cultivation method for interplanting peanuts in young orchard

Abstract

The invention discloses a single-grain intensive-sowing cultivation method for interplanting peanuts in a young orchard. Small and medium-sized fruit varieties with shade tolerance and high yield areselected, decomposed organic fertilizer is additionally applied in the forest orchard, after a compound fertilizer is mixed, the row spacing and plant spacing of sowing are determined according to thecrown sizes and trunk heights of young trees of the corresponding varieties, ridge culture is performed on the forest orchard around May 5, then film mulching, chemical weeding and sowing are carriedout according to seasonal varieties, when 90% or above of the plants in the orchard yellow and the seed coats are mature, harvesting should be carried out in time, peanut seeds are treated through apretreatment coating method to increase the survival rate of the peanut seeds, the land can be economically utilized, and the light energy utilization rate is increased; space is rationally utilized,and three-dimensional agriculture is developed; the soil is improved, the fertility is improved, peanuts have a better nitrogen fixation effect, and the nitrogen content of the soil in the orchard where the peanuts are interplanted can be increased.

Description

technical field [0001] The invention relates to the technical field of orchard planting, in particular to a cultivation method for single seed precision sowing of intercropping peanuts in young orchards. Background technique [0002] Peanut, formerly known as groundnut, is a kind of nut with abundant production and wide consumption in my country, also known as "longevity fruit" and "nidou". Rosaceae, leguminous annual herb, stem erect or prostrate, 30-80 cm long, wing petals and keel petals separated, pods 2-5 cm long, 1-1.3 cm wide, swollen, pods thick, flowering and fruiting stage 6 -August, it is mainly distributed in Brazil, China, Egypt and other places, and can be used as a raw material for cosmetics such as soap and hair tonic. [0003] Peanut is an annual herb with abundant nodules at the root; the stem is erect or prostrate, 30-80 cm long, the stem and branches are ribbed, covered with yellow villous hairs, and then becomes glabrous. Leaves usually have 2 pairs of...

Problems solved by technology

[0004] The amount of peanuts used is large, accounting for about 8% to 10% of the peanut production. The single-seed precision sowing of peanuts replaces the double-seed hole sowing, which has become a new production and cultivation technology that saves costs and increases efficiency. Young orchards refer to those before the full fruit period In the orchard, it takes 4 to 5 years from planting to the first full fruit period. At this time, the canopy of the fruit trees is small, and the orchard coverage area is about 30% to 40%. The land utilization rate is low, which affects the overall sowing efficiency.
