Embodiment

[0041] 1 Materials and methods

[0042] 1.1 Conventional planting of spring peanuts in continuous cropping

[0043] Set up a field plot experiment and select plots that have been continuously cropping peanuts for 3 years. Adopt the conventional planting method (after the peanuts are harvested, fall in winter, and continue to plant peanuts in the following year), the area of ​​the plot is 0.5 mu, repeat 3 times, and arrange randomly.

[0044] (1) Winter slack period

[0045] After the peanuts are harvested, the plots are put aside for winter slack until the peanuts are planted in the next spring.

[0046] (2) Soil preparation in spring

[0047] Before planting spring peanuts, plow and prepare the land in due course;

[0048] (3) fertilization

[0049] Rational application of chemical fertilizers, 30-50kg of nitrogen, phosphorus and potassium (15-15-15) compound fertilizer per mu;

[0050] (4) Timely sowing

[0051] Sowing is carried out when the ground temperature of the...

Abstract

The invention discloses a planting method capable of preventing peanut continuous cropping obstacle and belongs to the technical field of crop planting. According to the planting method capable of preventing the peanut continuous cropping obstacle, orychophragmus violaceus is sowed at land after peanut harvesting and used for turning over of green manure before planting of continuous cropping peanut. The peanut is spring peanut and the land is winter fallowing field. Through turning over of green manure by the orychophragmus violaceus, on one hand, the organic matter content of soil can be increased and organic fertilizer basal application can be reduced; on the other hand, the microbial groups of soil in the continuous cropping peanut field can be changed. By means of the planting method,manpower and material resource consumption caused by intensive cultivation of soil can be substantially reduced, the transpiration of the soil can be reduced, the utilization rate and productivity ofthe soil can be increased, and the peanut yield can be increased.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a planting method for preventing continuous cropping obstacles of peanuts. Background technique [0002] Peanut is an important economic crop and oil crop in my country. In 2016, the planting area of ​​peanut in my country was 69.95 million mu, and the main peanut production areas are mainly concentrated in Henan Province, Shandong Province and Liaoning Province. Due to the relatively high benefits of peanut planting and the limitation of planting soil, peanut planting is often carried out in a continuous and large-scale manner for many years, and some have even been cultivated continuously for 10 to 20 years. [0003] Peanut is a crop with serious obstacles to continuous cropping, and the longer the continuous cropping period, the greater the yield reduction. [0004] Peanut continuous cropping has the following disadvantages: [0005] (1) Continuous cropping...
