Paddy rice cultivation method of double-season mechanized straw returning to field

Abstract

The invention discloses a paddy rice cultivation method of double-season mechanized straw returning to field. The method comprises following steps: mechanized crushing of straw returning to field, returning straw to fields, field growing management after returning straw to fields and disease and pest diseases control.The paddy rice cultivation method of double-season mechanized straw returning to field has following beneficial effects: through an original-position full-amount returning mode, resources of double-season early rice and late rice can be reasonably utilized; straw is circularly utilized on the spot and workload is decreased; in addition, environmental contamination and hardened and impervious soil caused by burning of straw are avoided so that soil is improved and fertility betterment is achieved reasonably and soil fertility is improved; fertilizer applying amount is reduced and soil quality is improved; and the method is beneficial for stable and high-yield of double-season early rice and late rice.

Description

technical field

[0001] The invention belongs to the field of agricultural production, and relates to a rice cultivation method for double-season mechanized rice straw returning to the field. Background technique

[0002] my country's crop straw resources are very rich, and about 600 million tons of straw are produced every year, and rice straw accounts for about 1 / 3 of the total straw, especially in double-cropping rice areas. Rice straw is a carbon-rich energy source, an important organic fertilizer source, rich in mineral nutrients such as nitrogen, phosphorus, potassium, and silicon. The promotion of rice straw returning to the field plays an important role in maintaining and improving soil fertility, improving soil physical and chemical properties and biological properties, improving crop yield and quality, and reducing fertilization costs.

[0003] With the reduction of farming by individual households in rural areas, there are fewer and fewer rice straws and gaskets b...

Embodiment 1

[0022] 1. The location is selected as the double-cropping rice production area in Jinxian County, Jiangxi Province—the national cultivated land quality monitoring point base in Yangxi Village, Wenzhen Town, located at 116°5'29.73″ east longitude and 28°20’7.14″ north latitude. The fields are flat and the ecological conditions are good. The soil is paddy soil developed from Quaternary red clay. The test soil organic matter is 34.16g / kg, total nitrogen is 2.271g / kg, alkaline nitrogen is 126.0mg / kg, available phosphorus (P 2 o 5 )31.34mg / kg, available potassium (K 2 O) 97.9 mg / kg, pH 5.48. Early and late rice test crop varieties are Luliangyou 996 and Wufengyou T025, and the test is set up for the treatment of rice straw returning to the field in full amount (planting for the present invention), rice straw burning ash returning to the field and rice straw not returning to the field, each processing nitrogen, phosphorus, and potassium The dosage is equal, the amount of pure N ...

Embodiment 2

[0046] From 2014 to 2015, demonstration and promotion were carried out in Yijiang Township, Xingan County, and Wenzhen Town, Jinxian County, Jiangxi Province. The demonstration and promotion areas of early and late rice were 2.5 million mu respectively. The specific implementation methods were basically the same as in Example 1. The early rice was sown on March 20, transplanted on April 23, and harvested mechanically on July 15. The tested variety was Zhongjiazao 17. The average output of early rice straw returned to the field is 490 kg / mu, and the average cost savings and efficiency increase are 44.85 yuan. After the early rice is mechanically harvested, leave 15 cm of rice stubble, mechanically crush 8 cm, spread the rice straw on the field, and evenly return it to the field. Sprinkle 2 kg of straw decomposing agent per mu, soak the field with water, and add 8 kg of ammonium bicarbonate. The late rice was sown on June 25, transplanted on July 20, and harvested mechanically o...
