Embodiment 1

[0018] This example was carried out in Zhuangkou Village, Dalu Township, Jingyuan County, Gansu Province, China.

[0019] The experiment of combining potato varieties and densities showed that the potato varieties were upright early-maturing type Feiwu Ruita, semi-upright mid-maturing type Longshu No. 3, and developed late-maturing type Weihui No. 2. The planting specifications of potatoes and soybeans are planted in wide and narrow rows. The wide row of potatoes is 110 cm, and the narrow row on the ridge is 40 cm. When sowing soybeans, 2 rows of soybeans are planted in the wide row of potatoes. The soybean variety is late-maturing Jidou 17 with a density of 9500 plants / mu. The test results show that when the erect early-maturing variety Favori is at a medium density of 3500 plants / mu, potatoes and soybeans can simultaneously obtain higher yields, and the comprehensive benefit is the highest.

Embodiment 2

[0023] This example was carried out in Zhuangkou Village, Dalu Township, Jingyuan County, Gansu Province, China.

[0024] Soybean varieties at different maturity stages were tested, and the planting specifications of potatoes and soybeans were planted in wide and narrow rows. The wide row of potatoes was 110 cm, and the narrow row on the ridge was 40 cm. Potatoes and soybeans are spaced 35 cm apart. The potato variety is Fevorita, with a density of 3,500 plants / mu. The test results showed that the medium-late-maturing variety Jidou 17, with a density of 9,500 plants / mu, had the most significant yield-increasing effect, with a yield of 242.05 kg per mu.

Embodiment 3

[0028] This example was carried out in Zhuangkou Village, Dalu Township, Jingyuan County, Gansu Province, China.

[0029] Using the combination of soybean sowing date and density, the planting specifications of potatoes and soybeans are planted in wide and narrow rows. The wide row of potatoes is 110 cm, and the narrow row on the ridge is 40 cm; 40 cm, the distance between potatoes and soybeans is 35 cm; the potato variety is Favorita, and the density is 3500 plants / mu. The test results showed that the mid-to-late maturing variety Jidou 17 had the highest soybean yield when it was sown in the early, middle and high density, that is, from May 15th to 25th, and when 9500-12000 plants were planted per mu.

Abstract

The invention relates to a compensation cultivation method for interplanting potato with soybean in the northwest of China, belonging to crop cultivation in the technical field of crop cultivation. According to the interspecies interaction principle of the agricultural ecology, in the method, the complementary utilization of nutrients and luminous energy in the same habitat is realized by the difference of the ecological niche of the potato and the soybean, and the purposes on improving resource utilization efficiency and soil production rate and increasing the income of farmers are achieved. The method comprises the following specific steps: selecting early-maturing spring potato species with vertical plant, few branches and shorter plants; and selecting drought-enduring and lodging-resistance late-maturing summer soybean species; early sowing the potato in due time according to temperature rebound condition; sowing the soybean in time before or after Grain Rain in the medium growth period of the potato; planting the potato and the soybean in narrow and wide rows, wherein the wide row of the potato is 110cm, and the narrow row on the ridge is 40cm; when the soybean is sown, planting two rows of soybean in the wide row of the potato, wherein the line space of the soybean is 40cm, and the line space between the potato and the soybean is 35cm; planting the potato in a double-row, single-plant and staggered-hole mode; and carrying out bunch planting on the soybean in a double-row, three-plant and staggered-hole mode.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for compensating cultivation of potatoes and soybeans. Background technique [0002] Northwest China, represented by Gansu, Shaanxi, and Ningxia, is a typical dryland agricultural production area in my country. The climate is dry, the rainfall is low and concentrated in June-September, and the temperature is low in spring and winter. Mainly. Potato is a major food crop developed in this area in recent years, which can adapt to the local climate characteristics and produce high yields, and can also drive farmers to increase their income and become rich. The planting area has increased year by year, reaching 1,235,600 hectares in 2008. Potatoes are grown in various seasons. Spring and autumn potatoes are suitable for Northwest China, and the varieties have various maturity periods, including early, middle and late varieties. Since the vegetative organ...
