Problems solved by technology

Since the reform and opening up, with the strategic transfer of rural surplus labor and the adjustment of rural industrial structure, winter agricultural production has shown a gradual downward trend, resulting in a sharp increase in the area of ​​winter fallow fields, with an area of ​​about 20 million hm 2 The coverage of paddy fields in winter is further reduced, resulting in a waste of resources and energy, which seriously restricts the sustainable development of agriculture in this region
At the same time, due to the long-term continuous cropping of rice caused by winter slack, serious pests and diseases are prone to occur, and the lack of nutrients in the soil affects the physical and chemical properties of rice field soil.

Embodiment 1

[0082] Embodiment 1: Optimal yield spring potato variety screening test

[0083] The experiment was carried out in Songjiazui Town, Huarong County, Hunan Province, a double-cropping rice area with deep, flat and fertile soil. On the premise that the sowing date, density, fertilizer amount and field management were consistent, the paddy fields were prepared by rotary tillage. The ditch and ridges are divided into compartments, the width of the compartment is 1.8 meters, the width of the trench is 0.2 meters, and the depth of the trench is 0.15 meters; it was sown on December 25, 2013. The potato planting specifications are 90 cm apart, 15 cm apart, and the seeding rate per mu is 150 kg. The planting density per mu is 5000 to 5200 plants. The amount of base fertilizer per mu is 50 kg of potassium sulfate compound fertilizer, 20 kg of potassium sulfate, and 100 kg of diammonium. The results are shown in Table 1.

Embodiment 2

[0087] Embodiment 2: Potato different planting density test

[0088] Using Zhongshu 5, a potato variety suitable for double-cropping rice fields that can obtain high yields, as a material, the experiment was carried out in Songjiazui Town, Huarong County, Hunan Province, where the soil layer is deep, flat and fertile. Rotary tillage, Ditching and compartment ridges, compartment surface width 1.8 meters, trench width 0.2 meters, trench depth 0.15 meters; sowing time is December 25, 2013. When sowing, the effects of 5 different planting densities of 3500 holes / mu, 4000 holes / mu, 4500 holes / mu, 5000 holes / mu, and 5500 holes / mu on potato yield were studied. The results are shown in Table 2.

[0090] Density (plant / mu)

[0091] From the above test results, it can be seen that the yield of spring potatoes showed an increasing trend with the increase of planting density. The spring potato yield was t...

Embodiment 3

[0092] Example 3: Research on Rational Connection Techniques of Different Early and Late Rice Varieties

[0093] According to the ripening period of early and late rice, a stubble connection test of early and late rice varieties with different maturity stages was selected in Sanxianhu Town, Nanxian County, Hunan Province, a double-cropping rice area with deep, flat and fertile soil. The high-yield cultivation of double-cropping rice mainly includes varieties selection, seedling raising and transplanting, field management, scientific fertilization, weeding, irrigation, pest control, and straw turning over and returning to the field. The annual rice yield results of different hybrid early and late rice varieties are shown in Table 3.

Abstract

The invention provides a solanum tuberosum and double cropping rice rotation crop rotation culture method for improving a south double cropping rice paddy soil micro-aggregate structure, and belongs to the field of agricultural production. The method mainly comprises the first step of solanum tuberosum high-yield cultivation and the second step of early rice and late rice high-yield cultivation, wherein the first step comprises the substeps of preparation before seeding, variety selection, cutting of seed solanum tuberosum, seeding at suitable time and coverage of straw and a mulching film, field management comprising timely film breaking, topdressing, drainage and insect disease prevention, timely harvesting, and field returning of solanum tuberosum stem leaves and straw for coverage, and the second step comprises the substeps of variety selection, seedling transplanting, filed management comprising scientific fertilization, weeding, irrigation and insect disease prevention, timely harvesting and field returning of straw. By means of the method, south double cropping rice paddy winter agriculture can be reasonably developed, the rice paddy soil micro-aggregate structure is effectively improved, soil is fertilized, economic benefits of solanum tuberosum in one season are increased on the basis of ensuring the double cropping rice yield, the purposes of improving the rice paddy soil structure and obtaining high-yield year-round crops are achieved, and the popularization value is high.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a potato and double-cropping rice rotation cultivation method for improving the soil micro-agglomeration structure of a southern double-cropping rice field. Background technique [0002] Crop rotation refers to the method of planting different crops or multiple crop combinations sequentially between seasons and years on the same field, also known as multiple crop rotation. Reasonable crop rotation can eliminate or reduce the number of various pathogens in the soil, reduce diseases, control weeds, make balanced use of soil nutrients, and adjust soil fertility, which has high ecological and economic benefits. [0003] Potato (Solanum tuberosum), a perennial herb belonging to the family Solanaceae, has edible tubers and is the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes, also known as ground eggs, potatoes, yams, ...
