Embodiment Construction

[0018] 1.1 The location is selected in Community 2, Tieqiao Village, Daguan Town, Nanchuan District. Located at 106°59″38.3′ east longitude, 29°14″32.1′ north latitude, 716 meters above sea level, only 500 meters away from the comprehensive test base in Nanchuan District, the ecological conditions are good, it belongs to the middle hilly landform, the upper part of the hill is dense pine forest, and the distribution of test rice fields Yukuangu is the main rice producing area in Nanchuan District.

[0019] 1.2 Soil

[0020] The soil is submerged paddy soil developed and enriched by the Shaximiao purple sand shale in the Middle Jurassic system. The planting system is mostly one-season rice, and rarely rice-oil (rapeseed) or rice-vegetable double cropping. The nutrient status of the tested soil is shown in Table 1.

Abstract

The invention discloses a planting method for the high yield of rice. The method comprises the following steps: A, soil detection and recipe: determining the organic-inorganic compound fertilizer with a reasonable recipe; B, seed selection: selecting a generalized variety with high yield as a seed; C, cultivation: carrying out timely seeding on March 20th to March 25th, adopting humidified seedling culture and dry land seedling culture, and carrying out the standardized cultivation with alternate wide and narrow rows; D, recipe fertilizer application: carrying out the heavy basic dressing and carrying out the top dressing at young ear formation stage complementarily; and E, comprehensive pest prevention and control: 7 to 10 days after planting, applying the herbicide for the rice field once, applying the insect destroying pesticide once at the early stage of tiller so as to prevent and control paddy borers. The method can reduce the amount of applied chemical fertilizer by about 50 percent, reduce the industrial energy consumption, reduce the environmental pollution and farmland pollution, improve the product quality, alleviate the damage caused by diseases and insects, particularly the sheath blight, facilitate the production of nuisance free rice, and realize the stable and high yield and remarkable benefits.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a high-yield rice planting method that saves costs and increases efficiency. Background technique [0002] At present, with the existing rice cultivation technology, farmers routinely cultivate and plant 5000-8000 nests per mu, 2 plants in the nest, few basic seedlings (0.5-0.75 kg of seeds), 1.0-15,000 basic seedlings per mu, mainly relying on a large number of Fertilization to increase yield, fertilization per mu (N-P-K) 16.75 kg, fertilization per mu is more than 100 yuan, the yield per mu is only 500-550 kg, deducting soil yield (350-450 kg / mu), the increase in yield per mu is only 50-100 kg, the actual pure The income is less than 100 yuan / mu, and part of the income from increasing production is not enough for fertilizers, seeds, and pesticides, which seriously affects farmers' enthusiasm for growing grain. The existing problems are: the planting is too sparse, t...
