Embodiment 1

[0015] A planting method suitable for increasing yield and income in red soil dry land, selecting early-maturing potato varieties with strong drought tolerance in the early growth stage, selecting compact and semi-compact spring corn varieties suitable for intercropping, and selecting summer soybean varieties with strong drought tolerance in the later stage; Potatoes are intercropped with spring corn intercropped with summer soybeans; potatoes are planted in the middle and late January of each year, and harvested in mid-May; spring corn is sown in early April and harvested in late July; summer soybeans are planted 20-30 days after potato harvest. Sow every day and harvest in early October;

[0016] Among them, the bandwidth is 240cm, the row spacing between potatoes and potatoes is 60cm, and the plant spacing is 25cm; the row spacing between potatoes and spring corn is 70cm, and two rows of spring corn are planted between two rows of potatoes; the row spacing between spring cor...

Embodiment 2

[0020] S1. The planting mode is potato intercropping, spring corn intercropping and summer soybean intercropping;

[0021] S2. Select early-maturing potato varieties with strong drought tolerance in the early stage of growth, select compact and semi-compact spring corn varieties suitable for intercropping, and select summer soybean varieties with strong drought tolerance in the later stage;

[0022] S3. Potatoes are planted in the middle and late January of each year and harvested in mid-May; spring corn is sown in early April and harvested in late July; summer soybeans are sown 20-30 days after potato harvest and harvested in early October; the planting process is as follows :

[0023] 1) Dig ditch in the middle and late January, apply basal fertilizer before potato planting, and the basal fertilizer is N:P 2 o 5 :K 2 O=15:15:15 compound fertilizer, the application rate is 700~800kg·hm -2 , served with rapeseed cake 1500kg·hm -2 .

[0024] 2) After the potato seed potat...

Abstract

The invention relates to the technical field of agriculture and discloses a suitable planting method for increasing the yield and increasing the harvest in red soil drylands. The method includes: selecting potato varieties with strong draught tolerance and early maturity, selecting compact and semi-compact corn varieties suitable for intercropping, and selecting summer soybean varieties with strong draught tolerance in the later stage; adopting the planting pattern of intercropping of potatoes, spring corn and summer soybean, wherein the potatoes are planted in trenches in the middle and laterJanuary of each year and harvest in mid-May, the spring corn is sown in early April, and the summer soybean is sown in 20-30 days after the potatoes are harvested. The pattern of intercropping of thepotatoes, spring corn and summer soybean, the summer soybean is planted after harvest of the early maturing potatoes, reasonable layout is achieved, the conventional one-year single cropping mode ischanged into one-year three-cropping interplanting mode, the utilization efficiency of water, light and heat resources is increased, and the income is also increased.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a production-increasing and income-increasing planting method suitable for red soil dry land. Background technique [0002] Red soil is an important soil type in southern my country, and the red soil dryland is the main component of the red soil area. The red soil area in the south has a tropical and subtropical climate, a long frost-free period, rich water, light and heat resources, superior natural conditions, and huge production potential. It is an important production base for grain, oil, cotton and fruits in my country. [0003] However, long-term strong leaching and weathering lead to low natural fertility of red soil, coupled with long-term irrational development and utilization, accelerated the impoverishment of soil fertility and nutrient loss, making the barren degree more serious, and the production potential cannot be fully utilized and digging. How to make fu...
