Embodiment 1

[0010] Embodiment 1: a kind of paddy rice no-till planting method, comprises the following steps:

[0011] 1) Weeding and insecticide: From September to October, when harvesting rice, it is necessary to cut evenly and leave shallow piles. After harvesting, flood the rice field with water to kill weeds. The depth of water is 5-10cm, allowing the water to evaporate naturally At the beginning of December, when there is no stagnant water in the paddy field, sprinkle 1000kg of quicklime per mu to kill weeds, insects, and suddenly freeze loose; in March to April of the next year, water again, with a water depth of 1 to 2cm, to facilitate the growth of weeds. For germination and soil softening, when there is no stagnant water in the paddy field, use 100-130 grams of "Nongnongle 747" or 150-180ml of 20% "Ge Wuzong" per mu to control weeds; in early May, water the paddy field again to keep the field moist , let the ungerminated weeds regenerate, and then sprinkle 800kg of 3:1 quicklime...

Abstract

The invention relates to a no-tillage plantation method for rice which belongs to the technical field of plantation. The method includes the following steps: 1) weeding, and killing pests; 2) planting: namely a step of performing irrigation on a paddy field again in late May or early June with the water depth being 2-3 cm, applying 100kg of compound fertilizer per mu as base fertilizer, and transplanting rice seedlings in the middle of rice pile spacing in the previous year; and 3) performing field management. According to the method, the work of ploughing and fine raking is omitted, the laborforce is reduced, and the working efficiency is improved; and through multiple weeding and insecticidal steps such as (1) irrigation for flooding and killing weeds, (2) application of quicklime for killing the weeds, killing the pests, and making soil loosen, (3) utilization of herbicide for weeding, and (4) application of mixed powder of quicklime and tobacco stem for weeding and killing the pests, weeds and diseases and pests can be effectively prevented, and planted seedlings do not produce seeding burnt phenomenon, thereby improving the rice output. In addition, the amount of pesticides and chemical fertilizer used by the method is small, and the method contributes to environmental protection.

Description

technical field [0001] The invention relates to a rice planting method, in particular to a rice no-tillage planting method, and belongs to the technical field of planting. Background technique [0002] No-tillage direct seeding of rice refers to the paddy fields that have not been plowed and harrowed after harvesting the previous season’s crops. First, weeds and seedlings of shattered grains are killed with biocidal herbicides. Finally, a rice cultivation technique in which rice seeds or rice seedlings are sown or planted in the field. But at present, there are the following problems in rice no-tillage cultivation: usually weeds regenerate, diseases and insect pests are rampant, and rotten seeds or seedlings are prone to appear, which in turn affects the yield, which brings great troubles to agricultural producers. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a no-tillage rice ...
