Problems solved by technology

However, due to the shallow rooting of direct-seeding rice, it is prone to lodging when encountering wind and rain in the later stage. In order to increase the yield, the sowing amount is greatly increased, which increases the production cost.

Abstract

The invention discloses a paddy direct planting method for flooded paddy field or winter-free paddy field. The method comprises the following steps of: preparing soil without tillage; fertilizing the paddy field; preparing germinated grains; opening a cage to sow; coating seeds with mud; weeding for the paddy field; homogenizing density and filling thinness; and applying flower promoting fertilizer. According to the paddy direct planting method, rice grains and germinated paddy grains are mixed and sown, so that seeds can be sown uniformly, and the degree of homogenizing density and filling thinness is specified in the seedling homogenizing process, basic seedlings are remarkably improved to promote remarkable increase of the number of effective ear of paddy, and the paddy yield is remarkably improved. According to the method, variety and seeding time of paddy are not constrained by crops for rotation, and the rice seedling has strong lodging-resistance capability. The method has the characteristics of high paddy yield, time and labor saving, cost reduction and high economical benefit.

Description

technical field [0001] The invention relates to a planting method of crops, in particular to a direct seeding planting method of rice used in winter paddy fields or winter fallow fields. Background technique [0002] Winter paddy fields refer to paddy fields that store water in winter and plant rice in the next year. Due to the complex terrain, lack of water conservancy facilities, poor irrigation conditions, and the influence of climatic factors, winter paddy fields are widely used in mountainous areas, hills, and areas that often suffer from drought. The paddy field is used to store water to ensure the water demand for rice planting in the coming year. The winter paddy field has higher fertility and strong water retention capacity. In the above-mentioned areas, due to the poor water source conditions, there are still a large part of winter fallow fields. Winter fallow fields refer to paddy fields that are fallow in winter to plant rice in the coming year. my country curre...
