Embodiment

[0027] Embodiment: A kind of preparation and raising seedling method of the straw swamp soil that is used for rice machine transplanting, comprises the following steps:

[0028] 1. Substrate preparation After crushing rape, rice, corn, cotton, soybean and other crop straws with a conventional straw crusher, add 1200 kg of biogas slurry and / or biogas residue and 2000 kg of loam to 1000 kg of crop straw, fully Mix evenly, knead into balls with hands when dry or wet, and disperse on the ground, then stack and retting, cover with woven bags or plastic cloth to prevent rainwater, do not cover tightly, to prevent airtight, it is advisable for the straw to turn brown, that is, Got straw swamp soil.

[0029] 2. Substrate packing Put the prepared substrate into the rice mechanical planting line to pack the seedling trays, adjust the thickness of each tray to 25mm, and water thoroughly.

[0030] 3. Sowing and raising seedlings The sowing rate of conventional seeds is 120-130 g / disc...

Abstract

The invention relates to a method for preparing straw and biogas manure soil used for rice transplanting through a rice machine and culturing rice seedlings. The method includes the following steps of matrix preparation, placing of matrixes into a disc, sowing and seedling culture, seedling-stage temperature control, water management and fertilizer and plant disease and insect pest management. A large number of straws, existing in agricultural production, of crops like rapes, corn and rice are utilized, mechanically smashed, mixed with biogas manure and a small amount of soil and soaked, and accordingly a novel rice machine seedling culture matrix full in nutrition ingredient, light in weight and capable of being transported for a long time is prepared. Crop straws and biogas manure are effectively utilized, and therefore pollution to the rural environment is reduced; seedlings with high quality are cultured.

Description

technical field [0001] The invention relates to crop cultivation technology, in particular to a method for preparing straw marsh soil for rice transplanting by machine and raising seedlings. Background technique [0002] The machine-transplanted rice seedling raising method is mainly the mechanized seedling raising assembly line seedling tray raising. This seedling raising method needs to use a large amount of fertile soil as nutrient soil, causing serious damage to a large number of fertile soil layers and vegetation, high-quality farmland is destroyed, and high-quality mountain vegetation is destroyed; many grain functional areas and agricultural machinery professional cooperatives have no high-quality soil. Desirable, affecting the sustainable development of agriculture. Herbicide residues in dryland crops can easily cause deformity and death of seedlings; seedlings grown in nutrient soil have the characteristics of less root system, weak seedlings, heavy weight, and eas...
