Simple direct seeding method for hilly areas

Abstract

The invention belongs to the technical field of rice planting, and discloses a simple direct seeding method for hilly areas. 2-3 Days before seeding, seeds are soaked, water is replaced every 8-12 hours, before seeding, water of the seeds is removed, and the seeds are drained completely at least three hours in advance; during seed dressing, a seed dressing agent special for direct seeding is usedfor treating the seeds, and seed dressing is conducted immediately when the seeds need to be used; before or after the Qingming Festival, seeding and fertilizer application are conducted at the same time; after seeding, weeds are removed and controlled in time; after leafing of rice, in the period of three leaf and one core formation of rice seedlings, a special weed killer and a special weed controlling agent for direct seeding are sprayed to the rice, dressing of 30 kg / mu of a weaning fertilizer is conducted, there is shallow water among rows in a field, and 3-5 centimeters of a water layeris kept; in the period of five leaf formation of the rice seedlings, before booting, the weed killer special for the direct seeding is sprayed to the portions with weeds. Compared with traditional manual transplanting, seeding cultivation and transplanting are saved, a large amount of manpower and a large number of material resources and finial resources are saved, the problem of manpower shortagecan be solved, the cultivation efficiency can be effectively improved in the rice production process, the final yield of rice can be effectively increased in the rice production process, and the method has important significance on achieving the light-weight trend, professionalization and large-scale production of rice production.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a simple direct-seeding method of rice in hilly areas. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: at the beginning of this century, along with the development of my country's industry and the acceleration of urbanization, according to statistics, about 15 million young and middle-aged laborers flock to cities in rural areas of my country every year to engage in agricultural production. Most of them are the elderly and women, resulting in a decline in the quantity and quality of the rural labor force, an increase in labor costs, and a sharp drop in the income of rice farmers. The traditional transplanting of rice, which is mainly characterized by artificial seedling transplanting, has a large demand for labor, high production costs, and low production efficiency, resulting in many farmers reduc...

Problems solved by technology

Taking Chongqing as an example, there are five major hidden dangers in planting direct-broadcast rice in hilly areas. They are drought and little rain in hilly areas, small and chaotic fields, very scarce water resources, and extremely difficult water for rice production. The impact of direct seeding is great; the unevenness of the whole field and the lack of water in the field affect chemical weeding, resulting in serious weed damage and reduced yield; uneven sowing and insufficient effective tillering reduce yield; direct seeding has shallow root system, which is easy to lodging and cause reduced yield

These problems can easily lead to reduced production or no harvest, which seriously restricts the development of direct seeding of rice in hilly areas

[0004] To sum up, the existing problems in the prior art are: the planting of direct seeding rice in hilly areas has drought and little rain, the fields are small and chaotic, water resources are very scarce, and water for rice production is extremely difficult; bird damage, rodent damage, plant diseases and insect pests in hilly areas Serious, it has a great impact on direct seeding; the unevenness of the whole field and the lack of water in the field affect chemical weeding, resulting in serious weed damage and reduced production; uneven sowing, insufficient effective tillering and reduced yield; direct seeding has shallow roots, which are easy to lodging and cause reduced yield, which seriously restricts hilly areas The development of rice direct seeding

[0005] The difficulty and significance of solving the above-mentioned technical problems: In order to successfully solve the above-mentioned problems, it is first necessary to select drought-resistant, lodging-resistant and suitable for direct seeding from thousands of varieties, and it needs to be carried out for a long time on a year-by-year basis. The field grass items in each area of ​​the hilly area are different, and there are many stubborn weeds. It is necessary to screen out a pesticide that is suitable for the entire hilly area and has no harm to the rice, and multiple tests in many places are required; the air in the hilly area The humidity is high, the outbreak of pests and diseases is serious, and devastating pests and diseases often occur, and the live broadcast increases the difficulty of pest control. Integrating a set of high-efficiency and low-toxic pest control solutions requires a large number of laboratory and field experiments
