Embodiment 1

[0034] 1. Choose a suitable paddy field, choose a hilly area in southern Jiangsu with the topographical features of hills, hills, and hills, and the hills formed in the lowest part of the terrain. The hills have sufficient water sources, smooth drainage and irrigation systems, and there are a certain proportion of hillside dry land and hilly fields in the surrounding area. The planting density is 7,000 holes per mu of rice fields.

[0035] 2. Selection and planting of green manure varieties in autumn and winter, mainly safflower, supplemented by a small amount of perennial ryegrass, the planting area ratio of safflower and perennial ryegrass is 7:3; from late September to early October, safflower is 2.0 The seeding rate of kg / mu is broadcast; the perennial ryegrass is broadcast or drilled at the seeding rate of 0.8kg / mu at the end of October.

[0036] 3. Water and fertilizer management of green manure, after sowing safflower and perennial ryegrass, pay attention to opening a s...

Abstract

The invention discloses a hilly downland eroded field ecological cyclic system construction method. The method comprises the following steps: 1, land patch selection; 2, autumn and winter green manure type selection and plantation; 3, water and fertilizer management of green manure; 4, gosling selection and seedling hardening; 5, green manure field goose shepherding; 6, goose slaughtering and green manure land returning; 7, paddy sprout cultivation and transplanting; 8, duckling selection and seedling hardening; 9, rice field duck management; 10, paddy rice management; 11, azolla putting; 12, forage supplement of ducks; 13, duck slaughtering; and 14, cyclical plantation of autumn and winter green manure. Compared to the prior art, disadvantages of environmental pollution, soil layer hardening and low economic benefits, caused by much consumption of fertilizers and pesticides in conventional paddy rice plantation are overcome, paddy rice planted by use of the method does not need external pesticides, consumption of the fertilizers is reduced by half, the quality of the paddy rice is greatly improved, the production benefits are increased, the ecological environment is improved, and the constructed ecological system is stable and lasting.

Description

technical field [0001] The invention relates to a method for constructing an ecological circulation system in hilly and hilly fields, belonging to the field of agriculture. Background technique [0002] At present, there are still a certain proportion of low-yield fields in the basic farmland in the hilly areas of southern Jiangsu, most of which are hilly and hilly fields. The main reason for the low yield in hilly and hilly fields is that the soil ploughing layer is shallow, nutrient-poor, often containing obstacle soil layer, easy to harden, and poor air permeability. In response to the development requirements of the "Thirteenth Five-Year Plan", it is of great significance to achieve the goal of storing grain in the ground and improve the quality of cultivated land in the hilly, hilly, and hilly fields of southern Jiangsu. Due to the special topography, this type of field is relatively scattered and has a certain drop, and the conventional unified fertilizer-cultivation ...
