Wide-narrow row combined with wide-narrow spacing hole-staggered planting method for rice

Abstract

The invention discloses a wide-narrow row combined with wide-narrow spacing hole-staggered planting method for rice. The planting method includes the following steps of raising rice seedlings, wherein a dry land is selected, and the rice seedlings with four leaves and one heart or five leaves and one heart are planted according to the seedling age requirement; compartment partitioning for transplanting, wherein the land is applied with base fertilizer and then harrowed two days before transplanting, a compartment partitioning device is used for compartment partitioning after land water is clarified, the seedlings are planted according to compartment partitioning marks, seedlings are planted in the land by the ratio of nine thousand and five hundred to ten thousand holes per mu, and two or three seedlings are planted in each hole in a spaced mode; performing formula fertilization; performing irrigation to promoting control; controlling diseases and pests. The wide-narrow row combined with wide-narrow spacing hole-staggered planting method for rice has the effect of double marginal advantages, and the grain setting number and the filled grain number of rice spikes are substantially increased; the ventilating and light penetrating effects are good, the solar energy use ratio is high, the rice seedlings are strong, tall and straight and grow vigorously, the tillering number per plant is large, stems are thick and strong, and disease and pest damage is relieved; a group and individuals coordinate, tillering capacity of per plant is high, the spikes are large, more grains are obtained, enough productive spike groups exist, the microclimate among plants is obviously improved, root systems are developed, the capacity for absorbing nutrients is improved, the spike rate per plant of rice is increased, and the yield increasing effect is remarkable.

Description

technical field [0001] The application belongs to the field of agricultural technology, and in particular relates to a method for planting staggered nests with wide and narrow rows of rice. Background technique [0002] Rice super-high-yield cultivation is the main subject of current research at home and abroad, and it is the direction of eternal development. The super-high-yield cultivation of rice needs to ensure the largest population, and at the same time fully coordinate between individuals and groups. This requires the field to achieve the maximum ventilation and light transmittance conditions under the premise of fully ensuring the planting density, in order to obtain the highest. Yield. [0003] Traditional rice planting methods have limitations in super-high-yield cultivation. At present, the rice planting methods popularized on a large scale in my country mainly include four types: compartment wide row equidistant planting, mechanized planting, wide and narrow ro...
