A kind of dry rice transplanting method

Abstract

The invention discloses a dry rice seedling transplanting method. The method is characterized by including the first step of seedling raising tray preparation, the second step of rice sowing and seedling raising, and the third step of rice seedling transplanting. The method has the advantages that by adopting the method, the rice yield can be increased; the survival rate of rice seedlings in dry land rice seedling transplanting can be guaranteed; rice seedling growth can be accelerated; water resources can be saved, and saved underground water or reservoir water can be used for dry-period irrigation; meanwhile, in dry land rice seedling transplanting, operation is convenient, and rice seedling transplanting efficiency is greatly improved; a coal ash matrix is used for seedling raising and has the advantages of low heavy metal content, high soil fertility, good breathability and high self-cleaning capacity, plant disease resistance can be improved by adopting the coal ash matrix which is beneficial to rice seedling production, and as the coal ash matrix contains no grass seed, the weeding issue is solved from the source; as the coal ash matrix is obtained by fermenting various wastes, on one hand, environmental pollution is reduced by fully utilizing the wastes, and on the other hand, the problem that soil is difficult to take for seedling raising is solved.

Description

Technical field: [0001] The invention relates to a rice transplanting method, in particular to a rice dry transplanting method. Background technique: [0002] The planting of rice includes two steps of raising seedlings and transplanting seedlings. Traditional rice seedling raising generally involves digging soil from a large field or taking mountain soil and putting it into a seedling container for rice seedling raising. After the seedling raising is completed, the rice seedlings are separated or removed from the seedling tray Pull out from the middle, and then use the traditional way of transplanting rice in water to transplant rice seedlings. The traditional rice planting method has the following disadvantages: 1. In order to ensure that the substrate of the rice seedling roots does not scatter and successfully complete the water transplanting when the rice seedlings are transplanted in water after the seedlings are raised, the roots between adjacent rice seedlings need t...

Problems solved by technology

The traditional rice planting method has the following disadvantages: 1. In order to ensure that the substrate of the rice seedling roots does not scatter and successfully complete the water transplanting when the rice seedlings are transplanted in water after the seedlings are raised, the roots between adjacent rice seedlings need to be cross-linked when growing seedlings. Together, the substrate at the root is fixed; in this way, the distance between rice plants is almost zero. Due to the high density of plant distance, in order to meet the needs of rice seedlings for ventilation and substrate supply, rice seedlings must be transplanted in water before tillering, so the rice seedling time Shorter, the growth period of rice is limited, which in turn affects the rice yield; 2. Using the traditional method of transplanting, generally 5-6 seedlings are inserted in a plant hole, because the main branch density in a plant hole is high, affecting tillering, tillering There are few branches, and the output and disease resistance of the branches are significantly higher than the main branch, so the rice yield is reduced; 3. Since the roots of the cultivated rice seedlings are linked together, when the rice is transplanted in water, it will inevitably damage the roots. Form certain damage, in order to ensure the survival rate of seedlings after transplanting, and can slow down the normal production of seedlings in a short period of time, it is necessary to insert water, but the operation of water inserting is inconvenient and the work efficiency is low; Generally in May, at this time, due to the influence of climatic conditions, the natural precipitation is small, and a large amount of groundwater, reservoir or lake water needs to be consumed for irrigation, which consumes a lot of water, wastes water resources, and increases the cost of planting; 5. The substrate used for seedling cultivation is in Excavating soil in large fields or taking mountain soil is difficult, time-consuming and laborious, and rice seedlings are prone to diseases. In addition, there are many grass seeds in the soil excavated in large fields, and a large amount of herbicide needs to be sprinkled in later weeding, which will affect the quality of rice.
