Problems solved by technology

[0004] In recent years, the state and local governments have formulated relevant technical standards to standardize the basic principles, construction content and technical requirements of land consolidation projects. After the rectification, the double-cropping rice yield still has the problem of not being able to recover in the short term

Embodiment 1

[0031] 1. Green manure planting and returning to the field

[0032] For the paddy fields that have not been planted after raising the fields, sow milk vetch on September 30 of the year when the project is completed, the variety is "Yujiang Daye", and the sowing rate is 30kg / hm 2 , the milk vetch fresh grass was turned over and returned to the field 15 days before the early rice was transplanted, and the returning amount (fresh weight) was 22.6t / hm 2 , adopt the method of tractor rotary tillage for plowing, and after plowing, the green manure plants should not be exposed;

[0033] The measured dry matter content in the milk vetch fresh grass is 9.8%, the dry weight nutrient content is 2.9% of total nitrogen, 0.3% of total phosphorus, and 4.4% of total potassium.

[0034] 2. Straw returning to the field

[0035]The early and late rice straws are mechanically harvested and returned to the field in full, and the straw corrosive agent is sprayed when the early rice straws are ret...

Embodiment 2

[0044] 1. Green manure planting and returning to the field

[0045] For the paddy fields that have been planted for one year after the field lifting, sow milk vetch on October 3 of the first year of planting, the variety is "Yujiang Daye", and the sowing rate is 30kg / hm 2 , the milk vetch fresh grass was turned over and returned to the field 18 days before the early rice was transplanted, and the returning amount (fresh weight) was 22.8t / hm 2 , adopt the method of tractor rotary tillage for plowing, and after plowing, the green manure plants should not be exposed;

[0046] The measured dry matter content in the milk vetch fresh grass is 10.1%, the dry weight nutrient content is 2.9% of total nitrogen, 0.3% of total phosphorus, and 4.2% of total potassium.

Embodiment 3

[0057] 1. Green manure planting and returning to the field

[0058] For the paddy fields that have been planted for 4 years after the field lifting, sow milk vetch on October 1 of the third year of planting, the variety is "Yujiang Daye", and the sowing rate is 30kg / hm 2 , the milk vetch fresh grass was turned over and returned to the field 15 days before the early rice was transplanted, and the returning amount (fresh weight) was 22.9t / hm 2 , adopt the method of tractor rotary tillage for plowing, and after plowing, the green manure plants should not be exposed;

[0059] The measured dry matter content in the milk vetch fresh grass is 10.3%, the dry weight nutrient content is 3.3% of total nitrogen, 0.3% of total phosphorus, and 4.4% of total potassium.

Abstract

The invention belongs to the technical field of planting, in particular to a double-cropping rice planting method based on newly remediated paddy yield improvement. After farmland remediation, green manure returning to field and straw returning to field are adopted, efficient water and manure utilization of rice is promoted through intermittent irrigation and fertilization optimization, and therefore, it is achieved that the yield of double-cropping rice in newly remediated farmland is restored and improved in a short time.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a double-cropping rice planting method based on the improvement of the yield of newly rehabilitated paddy fields. Background technique [0002] Land consolidation is the main means to strengthen the construction of basic farmland infrastructure, improve the quality of basic farmland, and improve the production conditions of basic farmland. To this end, my country has carried out large-scale land consolidation projects, promulgating and implementing the "National Land Development and Consolidation Plan (2001-2010)", "National Land Consolidation Plan (2011-2015)", "National Land Consolidation Plan 2016-2010". 2020" aims to increase the effective arable land area through farmland improvement projects, improve land quality and utilization efficiency, and improve production, living conditions and ecological environment. [0003] Land consolidation is a systematic project ...
