Embodiment 1

[0039] In 2016, in Wuduntaohai Town, Wengniute Banner, Chifeng City, Inner Mongolia Autonomous Region, 5 plots of 60 acres in total were used to experiment with the wide and narrow row dense planting method of the present invention.

[0040] A. Raising seedlings

[0041] 1. Variety selection

[0042] Selection of improved varieties: Tianyuan 113 is selected as the variety, which has strong stress resistance, lodging resistance, is suitable for dense planting, and has strong tillering ability, with 1-2 more tillers than ordinary varieties;

[0043] 2. Seed treatment

[0044] Use 20% salt water to select the seeds, mix the selected seeds with 2ML Soaking Spirit and water 10 kg, soak the seeds for 6 kg, remove the seeds after soaking for 4 days, and control the dryness for germination. 50% of the seeds are white and sowed;

[0045] 3. Seedling bed arrangement

[0046] The seedling bed is made of fertile loam soil, filled with water and soaked thoroughly. The seedling bed is se...

Abstract

The invention discloses a wide-and-narrow-row large-hill-number ultra-dense planting cultivation method for rice. The method comprises the following steps of seedling raising, wherein fine varieties are selected, seeds are processed, a seedling bed is arranged, and seeding and rice seedling field management are conducted; rice seedling transplanting, wherein according to a rice seedling transplanting mode, the width of the width of large ridges is 60 cm, and the width of small ridges is 30 cm; field management, water and fertilizer management enhancement, disease and pest control enhancement and promotion of early maturing; timely harvesting. According to the method, edge row advantages of rice can be fully utilized, and the ventilation and light-transmitting effects are good. Reasonable dense planting is achieved, the number of plants is increased by 30-60%, then the yield is increased, and the average yield is increased by 204.6 kg per mu. Occurrence of the diseases, like sheath blight, on the lower middle portion of rice is reduced, the pesticide consumption can be reduced, and the method is beneficial to reducing pesticide residues and improving the quality of rice.

Description

technical field [0001] The invention relates to a rice dense planting cultivation technique, in particular to a wide and narrow row dense planting cultivation method for improving the yield per unit area of ​​rice. Background technique [0002] Rice is one of the main food crops with a long history of cultivation in my country. Rice has high nutritional value, good palatability, and is easy to digest. It is not only the main food in my country, but also about half of the world's population uses rice as a staple food. Rice by-products are widely used. The rice bran is not only a concentrated feed for livestock, but also a raw material for medicine, and the chaff can be used as an industrial raw material. In addition to being used as livestock feed, edible fungus production raw materials and organic fertilizers, rice straw is also a raw material for the paper industry. Although the total annual production of rice in my country has developed rapidly, there is still a large ga...
