High-yield planting method for high-quality rice

Abstract

The invention discloses a high-yield planting method for high-quality rice. The high-yield planting method for high-quality rice comprises the following steps that (a) seeds are selected, wherein according to local ecological conditions, production conditions, economic conditions, cultivation level and the harm of plant diseases and insect pests, high-yield and high-quality varieties strong in disease and pest resisting capability, resistant to lodging, strong in tillering, high in ear-bearing tiller percentage, capable of bearing large ears, high in ear-bearing rate and suitable for local planting are selected through examination, approval, experiments and demonstration; (b) strong rice seedlings are cultivated, the seeds are spread thinly and air-dried for 2-3 days before sowing, the emergence rate and germinative force of the seeds are improved, early season rice seeds are soaked for 3-4 days, late rice seeds are soaked for 2-3 days, frequent water change is needed when the outsidetemperature is high, the seeds can also be soaked with warm water when the temperature is low in early spring to shorten the seed soaking time, and in-cellar germination acceleration can be adopted for seeds of early season rice and middle-season rice. The high-yield planting method has the advantages that breeding is performed by selecting excellent varieties, rice can be healthier and has certain disease preventing ability through reasonable seedling raising and seedling strengthening in the growth process, and high rice yield can be achieved through timely fertilization, weeding and diseaseand pest prevention.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a high-yield planting method of high-quality rice. Background technique [0002] China's rice sowing area accounts for 1 / 4 of the country's grain crops, while the output accounts for more than half. The cultivation history has been 14000-18000 years. It is an important food crop; in addition to edible caryopsis, it can be used to make starch, wine, and vinegar; rice bran can be used to make sugar, oil, and extract furfural for industrial and medical purposes; rice straw is good feed and papermaking raw materials and weaving materials. The buds and roots are used medicinally. Nearly half of the world's population, including almost all of East and Southeast Asia, eat rice. [0003] The Chinese patent whose publication number is CN106069431A discloses that it includes a rice planting area, a rice planting unit arranged in the rice planting area, a spray pipe arranged in the...

Problems solved by technology

[0004] The above-mentioned patent uses electronic monitoring to monitor the water level and trace elements in rice planting. This method is not convenient for large-scale adoption in rice planting, and the sampling results are accidental, which cannot effectively increase the yield. Therefore, further improvement is needed
