example 1

[0020] This embodiment is carried out in two counties, Yuximo Village, Shaqiao Town, Nanhua County, Yunnan Province (2350 meters above sea level, latitude 25゜N) and Malu Township, Huize County (2260 meters above sea level, latitude 27゜N). The total planting area is 1150 mu.

[0021] Planting method of the present invention: planting area is 1150 mus, and its step is as follows:

[0022] (1) The first ripe potato: Sow potatoes from late December 2010 to mid-January 2011, with a plant spacing of 40cm and a row spacing of 80cm. One plant is set for each pond, and 4000kg of potatoes are harvested from mid-May to early June of 2011. The period is 155-165 days, which is the first ripe. The sales price is 0.8 yuan / kg, equivalent to 3333kg per mu, and 2666.4 yuan per mu income;

[0023] (2) The third mature corn: the planning and transplanting of the wide and narrow rows of corn: 10-20 days before the harvest of the first ripe potatoes, the corn seedlings should be raised intensivel...

[0028] (1) The first ripe potatoes: Sow potatoes from late December 2010 to mid-January 2011. The plant spacing is 40cm, the row spacing is 80cm, and one plant is established in each pond. 3865kg of potatoes are harvested from mid-May to early June 2011. The period is 155-165 days, which is the first ripe. The sales price is 0.8 yuan / kg, equivalent to 3300kg per mu, and 2640 yuan per mu income;

[0029] (2) Wide and narrow row planning and transplanting of the third-ripe corn: 10-20 days before the harvest of the first-ripe potatoes, the corn seedlings should be raised intensively. It is 40cm, the wide row spacing is 160cm, the pond distance is 20cm, there are 2 seedlings per pond, the density is 4500 plants / mu, and the growth period is 118-125 days. In the first ten days of October 2011, 1385 kg of dry corn kernels were harvested, which was the third crop, equivalent to 650.3 kg per mu, calculated at 2.2 yuan / kg, and the income per mu was 1430.66 yuan.

[0034] (1) The first ripe potato: Sow potatoes from late December 2010 to mid-January 2011, with a plant spacing of 40 cm and a row spacing of 80 cm. One plant is established in each pond, and 3935 kg of potatoes are harvested from mid-May to early June 2011. The period is 155-165 days, which is the first ripe. The sales price is 0.8 yuan / kg, which is equivalent to 3315kg per mu, and the income per mu is 2652 yuan;

[0035](2) Wide and narrow row planning and transplanting of the third-ripe corn: 10-20 days before the harvest of the first-ripe potatoes, the corn seedlings should be raised intensively. It is 40cm, the wide row spacing is 160cm, the pond distance is 20cm, there are 2 seedlings per pond, the density is 4500 plants / mu, and the growth period is 118-125 days. In the first ten days of October 2011, 1415 kg of dry corn kernels were harvested, which was the third crop, equivalent to 664.8 kg per mu, calculated at 2.2 yuan / kg, and the income per mu was 1462.56 yuan.

Abstract

The invention discloses a four-crop-a-year cultivation method for a low-latitude high-elevation area dry land. The method is characterized in that the first crop is potato, the second crop is vegetable, the third crop is corn, and the four crop is cereal or vegetable; the potato is sown from the last ten days of December of last year to the middle ten days of January of the following year; the second-crop vegetable is sown when the third-crop corn is transplanted between corn lines; the third-crop corn is transplanted after the first-crop potato is harvested; and the four-crop cereal or vegetable is sown after the second-crop vegetable is harvested. According to the four-crop-a-year cultivation method for the low-latitude high-elevation area dry land, which is disclosed by the invention, the staggering and the collocation of different crops in time and space are fully considered, a proper cultivation mode is adopted to realize the four-crop-a-year cultivation method with high yield and high efficiency, good harvest is obtained, the multiple cropping index is improved, and the income of each acre is above 5300yuan. Compared with the traditional planting mode in the area, the economic income is improved by 41.6-66.87%, and a new cultivation technical mode is provided for the poverty alleviation and economic development of farmers in the area.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a four-crop farming method for dry land in low-latitude and high-altitude areas. Background technique [0002] In my country's low-latitude and high-altitude areas (21゜N~28゜N, altitude 2100~2400 meters) drylands plant food crops, and there are generally situations where two seasons are insufficient and one season is more than enough in a year. The multiple cropping index is low. The economic benefits are extremely low, even less than one thousand yuan. Potatoes, radishes, corn, and buckwheat are the main crops for rations, economic income, and feed sources for people in low-latitude plateau mountainous areas. At present, the dry land in this area mainly grows potatoes and corn for two seasons in a monocropping manner, which results in extremely low land utilization and yield. A reasonable intercropping model can intensively utilize natural resources such as light, heat,...
