Embodiment Construction

[0020] A high-quality and high-yield cultivation method for water-saving and drought-resistant rice, comprising the following specific steps:

[0021] (1) Site selection and site preparation: Select deep, loose and fertile loam soil for planting, use 15% glyphosate solution mixed with 20 kg of water per acre for weeding 15 days before site preparation, and then deep plow over 25cm to break up large soil clods , rake level and make fine, excavate a furrow every 3m, the width is 30cm, the depth is 20cm, which is convenient for field management such as fertilization, drainage and irrigation;

[0022] (2) Base fertilizer application: Before site preparation, apply 1000 kg of decomposed farmyard manure and 20 kg of compound fertilizer (nitrogen 15: phosphorus 15: potassium 15), deep plow the fertilizer into the soil and mix well;

[0023] (3) Seed treatment and sowing: Choose a sunny day to dry the seeds for 2 days, then mix 1000ml of the fungicide Kurasfenene Thiaclothiazide suspe...

Abstract

The invention discloses a high-quality high-yield cultivation method for water-saving drought-resistant rice. The method carries out cultivation on the water-saving drought-resistant rice in a mode ofa direct seeding field on the aspects of land selection, land preparation, application of base fertilizers, seed treatment, control of grass damage, water and fertilizer management and pest control,and carried out drought and moisture management in the whole process according to the needs of water in different growth stages of rice, thereby achieving the purpose of saving water by 50% or more. The method carries out balanced fertilization and sufficient application of base fertilizers in the cultivation process, and conducts topdressing according to fertilizer requirements for rice growth and development and target yield at a later stage and by combining local soil nutrient content, thereby achieving organic and inorganic combination, targeted supplementation of elements and the purposeof fertilizer saving. The method eliminates traditional land ploughing and leveling, seedling raising and transplanting and other complicated processes, simplifies the cultivation process and solves the problems of water sources, seasons and labor intensity, achieves the purposes of saving water, reducing fertilizers, saving pesticides and increasing production, has high economic benefits and is worth promoting.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a high-quality and high-yield cultivation method for water-saving and drought-resistant rice. Background technique [0002] Rice is the most important food crop in my country, and the sustainable development of rice production plays a decisive role in ensuring my country's food security. In recent years, a large number of high-yield and high-quality rice varieties have been bred in my country. However, in the actual production of low- and medium-yield fields accounting for more than 70% of the rice planting area, many of the current new varieties are difficult to play a role in increasing production. The per unit yield has been hovering for a long time, and the average per unit yield has not yet broken through 450 kg. On the other hand, my country's rice production is facing a major challenge of resources and environment. The increasingly serious rice diseases and insec...
