Embodiment Construction

[0009] Below in conjunction with embodiment the present invention is further described in detail.

[0010] From 2016 to 2017, the test was completed in the Rice Science and Technology Park of Heilongjiang Academy of Agricultural Reclamation Science; the test soil was white pulp soil, and the basic fertility was: organic matter 19.5g / kg, total nitrogen 1.089g / kg, available phosphorus 12.1mg / kg, available potassium 204mg / kg kg, pH7.0.

[0011] Test variety: Kendao 24; test fertilizers are urea (N content 46.4%), diammonium phosphate (N content 18%, P 2 o 5 content 46%) and potassium sulfate (K 2 O content 60%), and the amount of fertilizer applied is according to the local conventional amount.

[0012] 2 treatments were set up in the test, repeated 3 times, each plot area was 500 square meters, treatment 1: a novel paddy field plowing method of the present invention; processing 2: conventional paddy field plowing method.

[0013] Description of treatment 1: 18-20 centimeters...

Abstract

The invention relates to the technical field of agriculture, in particular to a paddy field tilling method, comprising: tilling after rice harvesting; soaking a paddy field with water that is 50% of water used in a conventional tilling method; preparing the field with a vibratory slurrying leveler, slurrying via mechanical vibration, and applying fertilizer and transplanting seedlings immediately after slurrying. The steps such as soil breaking, stubble burying, soil layer slurrying and leveling are finished by single operation, and fertilizer application and seedling transplanting can be performed immediately after slurrying. The novel paddy field tilling method provided herein optimizes preparation mode, soaking water usage and preparation time and accordingly has the advantages of few operation steps, low consumption of farming time, and low water usage; the method saves time, water and labor and has lower cost but increased efficiency, average yield increase of rice is 9% and above, economic benefit increase is 1800 Yuan / hectare, agricultural non-point source pollution is reduced, agricultural sustainable development is maintained, and the method has significant economic and ecological benefits.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a paddy field plowing method. Background technique [0002] Rice is native to tropical Asia, and after being widely planted in China, it gradually spread to all parts of the world. The rice grains produced by rice are called rice or rice after shelling. Nearly half of the world's population feeds on rice. Compared with other crops, The digestibility and absorption rate of nutrients contained in rice are relatively high, which is most suitable for the needs of the human body. Rice is a crop that requires a lot of water. In the past 30 years, the area of ​​rice planted in the northern cold region of my country has expanded rapidly, and the demand for water resources has also increased. At the same time, the utilization rate of water resources in agricultural production is low. How to save water and improve water quality? Resource utilization remains to be resolved. [0003] ...
