Planting method of intercropping potatoes overturning and mulching common vetch

Abstract

The invention discloses a planting method of intercropping potatoes overturning and mulching common vetch. The planting method mainly includes: planting two rows of the potatoes on the ridge when ridging is performed on the field where the potatoes are to be planted; meanwhile, sowing three rows of the common vetch in the ridge trench, wherein the sowing time of the common vetch is about April 30,the same as that of the potatoes; pouring water once a week before sowing to ensure the condition of sowing; performing intertillage and soil cultivating on the potatoes in early July, meanwhile crushing and overturning the common vetch, and improving the soil fertility, wherein at this time, the potatoes are at flowering stage, the growth is unaffected, and soil cultivation is beneficial to potato tuber formation and starch accumulation. The common vetch is a high-quality crop, can be used as a feed to feed livestock, and is beneficial to the development of animal husbandry, and the yield ofthe planted potatoes is high; the high-efficiency three-dimensional planting method is for unreasonable research and development of potato continuous-cropping obstacles and water management in the northern and pastoral region of the north, has the effects of fertilizing soil and improving the utilization rate of farmland light, heat, water and soil nutrient resources, and can solve the contradiction between forage and grain in the ecotone of agriculture and animal husbandry.

Description

technical field [0001] The invention relates to a planting method for intercropping potatoes and peas, in particular to a planting method for intercropping potatoes and covering peas. Background technique [0002] Potatoes are the main crops grown in the northern farming-pastoral transition zone, with a planting area of ​​168,000 hectares in 2018. However, due to long-term continuous cropping, large amount of fertilizer input and unreasonable irrigation, the farmland soil in this area becomes shallower, the nutrient cycle is unbalanced, soil properties deteriorate, and soil degradation problems such as severe wind and water erosion seriously affect the crop yield and quality. According to statistics, long-term unreasonable planting has caused the bottom of the farmland plow to thicken by 4-6cm, and the soil bulk density has increased from 1.03g / cm 3 increased to 1.57g / cm 3 , soil aggregates with particle size less than 0.25mm increased by 19.4% on average, soil organic mat...

Problems solved by technology

However, due to long-term continuous cropping, large amount of fertilizer input and unreasonable irrigation, the farmland soil in this area has become shallower, nutrient cycle imbalance, soil property degradation, severe wind erosion and water erosion and other soil degradation problems have seriously affected crop yield and quality.

According to statistics, long-term unreasonable planting has caused the bottom of the farmland plow to thicken by 4-6cm, and the soil bulk density has increased from 1.03g / cm 3 increased to 1.57g / cm 3 , soil aggregates with a particle size of less than 0.25mm increased by 19.4% on average, soil organic matter decreased by about 12.5%, surface runoff increased, and rainfall utilization efficiency decreased significantly
