Embodiment 1

[0028] A method for cultivating high-yield and drought-resistant rice, comprising the following steps:

[0029] (1) Seed selection: select common rice seeds as provenance;

[0030] (2) Site selection and site preparation: Use loose and fertile sandy or semi-sandy land as the planting site. Before site preparation, apply 100 kilograms of phosphorus and potassium fertilizers per mu, make ridges and make furrows, and apply sufficient water;

[0031] (3) Sowing: Soak the seeds soaked in salt water and sterilize them on the plowed land, and then spread a layer of fine soil;

[0032] (4) Transplanting and planting: After the seeds emerge, water for the first time, and at the same time calcium chloride, magnesium sulfate, copper sulfate, ferrous sulfate and water are mixed and stirred to form a solution to spray the seedlings, wherein, each component The dosage is: 10mg of calcium chloride, 20mg of magnesium sulfate, 0.02mg of copper sulfate, 1mg of ferrous sulfate, 1L of water, tra...

Abstract

The invention discloses a planting method of high-yield and drought-resisting rice. The method comprises the steps of seed selection, wherein common rice seeds are selected as a seed source; land selection and soil preparation, wherein loose and fertile sandiness or semi-sandiness soil is regarded as planting land; sowing; transplanting and planting; field management; disease and pest control, wherein before transplanting is conducted, dexon 500-fold dilusion added with water is adopted to be poured and sprinkled to per mu of land in the planting soil, and conducting nursery soil disinfection; after transplanting is conducted for 15 days, humic acid, chitosan and water are prepared into a solution to be sprayed onto leaves, and conducing spraying every 5-7 days. According to the planting method of the high-yield and drought-resisting rice, besides applying conventional fertilizers like urea in each stage in the growth of the rice, calcium chloride, magnesium sulfide, copper sulfate, ferrous sulfate, and irrigation water are prepared into a solution to be sprayed onto the leaves or be irrigated onto the land, and the dose of each component is adjusted according to all growth phases of the rice. According to the planting method of the high-yield and drought-resisting rice, high-yield and high-quality planting of the rice can also be achieved even in a drought land, and the stress resistance is strong.

Description

[0001] Technical field: [0002] The invention relates to the field of rice planting, in particular to a cultivation method for high-yield and drought-resistant rice. [0003] Background technique: [0004] Rice is one of the main food crops in my country, but due to its strict requirements on moisture and temperature conditions, its distribution in my country has regional characteristics. From a national perspective, the humid and rainy areas in the south are the main rice producing areas, while those in the north The lack of rainfall and low annual effective accumulated temperature limit the large-scale planting of rice. At present, the distribution of rice in the northern region is mostly limited to rivers, lakes and low-lying swamp areas, and the planting method is mainly transplanted in soaked fields. The yield and inter-annual precipitation show Obviously positive correlation, precipitation has become the key factor to determine the rice yield and planting area in the north...
