Embodiment 1

[0039] Substrate preparation: crush the sun-dried rape stalks into a 3mm crushed material with a conventional straw grinder, and take 10kg for later use. Weighing respectively 12g of detoxifying agent (70% dexon powder), water retaining agent (polyacrylamide) 30g, conditioner (10% paclobutrazol wettable powder) 20g, acid regulator (humic acid water-soluble fertilizer) 20g, nitrogen fertilizer (urea and urea-formaldehyde, mass ratio 1:1) 150g, phosphate fertilizer (ammonium phosphate) 50g, potash fertilizer (potassium sulfate) 50g.

[0040] Pour the disinfectant, water retaining agent, conditioner, acid regulator, nitrogen fertilizer, phosphate fertilizer, and potassium fertilizer into the basin respectively, add water, and pour it on the straw crushed material after it dissolves completely, mix well, and knead it into a ball with hands when dry or wet. It is advisable to disperse when it lands. Its water content was tested to be 72% and its pH was 5.5.

Abstract

The invention discloses a soilless straw matrix of rice dry-raising water pipe and a seedling culture method. The method includes the following steps that a seedbed and the soilless straw matrix are manufactured; by means of the deep-ditch and high-box mode, water and fertilizer are controlled and growth of rice seedlings is regulated through a seedling box, wherein the seedling age of seedlings transplanted by machines is prolonged by 5-10 days, and the crop rotation contradiction of rice transplantation is effectively relieved; meanwhile, the soilless straw matrix matched with seedling culture of the method is formed by smashing oilseed rape straw serving as the main raw material and adding disinfectant, a water-retaining agent, modifier, an acid regulating agent, fertilizer and the like; a plastic tray with the specification of 58.8 cm*28 cm*2 cm is used for seedling culture; seedlings grow in the disinfected and appropriate acid condition; growth of seedlings is regulated through the water control and fertilizer control measures in the seedling culture process, and therefore the aims of being strong in seedling, large in root number, thick in rod and green in leaf are achieved. Straw is directly used as the soilless straw matrix after being smashed, the production processes of soil taking, soil screening and the like are reduced, and the labor intensity of rice farmers is lowered.

Description

technical field [0001] Embodiments of the present invention relate to the field of soilless cultivation of rice, and more specifically, embodiments of the present invention relate to a soilless straw substrate and a method for raising seedlings of rice dry-cultivation water pipes. Background technique [0002] With the reduction of agricultural population, the acceleration of land circulation, the popularization of modern agricultural technology, the widespread use of agricultural machinery has become the general trend, the whole mechanization of rice production, the key is the mechanization of rice seedling raising and transplanting, mechanized assembly line seedling raising and machine transplanting Rice seedlings require a large amount of seedling substrate, self-made nutrient soil will consume fertile farming surface, and the popularization and application of soilless straw substrate has laid the foundation for the whole process of agricultural mechanization in rice produ...
