Embodiment 1

[0050] Select the rice seedling bed, apply 3kg of fermented and decomposed pig manure per square meter of the seedbed, and mix it with the seedbed soil, then arrange the seedling box according to the specifications of the box width of 1.2m, the box ditch width of 0.3m, and the box height of 0.1m. Next, 30 g of urea and 50 g of superphosphate were applied per square meter of seedling box. Fermented and decomposed pig manure is an organic fertilizer that fully ferments pig manure under natural conditions.

[0051] Crush the rapeseed stalks to below 3 mm, then add water to the rapeseed stalks, stir to obtain a seedling-raising substrate with a water content of 80% by weight, and place 200 g of rapeseed seedling-raising substrates in each seedling tray with a size of 58.8cm×28cm×2cm. In the seedling tray, level and compact it into a seedling raising matrix with a thickness of 2-2.5cm, and then pour water into the seedling tray until the water at the bottom of the seedling tray rea...

Embodiment 2

[0056] Select the paddy rice seedling bed, apply 3kg of fermented and decomposed chicken manure per square meter of the seedbed, and mix it with the seedbed soil, then arrange the seedling box according to the specifications of the box width of 1.2m, the box ditch width of 0.3m, and the box height of 0.1m. Then apply 30g urea and 50g superphosphate fertilizer with every square meter seedling box. Fermented and decomposed chicken manure is an organic fertilizer made by composting and fermenting chicken manure under natural conditions.

[0057] Crush the rice straw to below 3 mm, then add water to the rice straw, stir to obtain a seedling raising substrate with a water content of 80% by weight, place 200 g of the rice straw seedling raising substrate in each seedling tray, and place the rice straw seedling raising substrate in a size of 58.8cm×28cm×2cm In the seedling tray, level and compact it into a seedling raising matrix with a thickness of 2 to 2.5 cm, and then pour water i...

Embodiment 3

[0062] Select a wheat seedling bed, apply 1.5kg of fermented and decomposed chicken manure and 1.5kg of fermented and decomposed pig manure per square meter of seedbed, and mix with the seedbed soil, and then according to the width of the box 1.4m, the width of the box ditch 0.3m, the height of the box The specification of 0.15m is used to arrange the seedling box, and then apply 30g of urea and 50g of superphosphate phosphate fertilizer per square meter of the seedling box. Fermented and decomposed chicken manure is an organic fertilizer that ferments and decomposes chicken manure under natural conditions. Fermented and decomposed pig manure is an organic fertilizer that fermented and decomposed cow manure under natural conditions.

[0063] Crush the wheat straw to less than 3mm, then add water to the wheat straw, stir to obtain a seedling raising substrate with a water content of 80% by weight, place 200g of the wheat straw seedling raising substrate in each seedling tray in...

Abstract

The invention discloses a rice seedling raising method for rice seedling transplantation of a soilless straw substrate rice seedling transplanter. The method comprises the following steps: selecting a rice seedling raising bed; applying 3-5 kg of fermented and decomposed organic fertilizer every square meter of the seedling bed; uniformly mixing with the soil of the seedling bed; then tidying rice seedling compartments; next applying 20-30 g of nitrogen fertilizer and 30-50 g of phosphorus fertilizer every square meter of rice seedling compartment; smashing the straws to be below 3 mm; then adding water into the straws and stirring to obtain the rice seedling raising substrate with water content of 75-85 percent by weight; placing 180-250 g of the rice seedling raising substrate in each rice seedling tray, leveling and compacting the substrate into the rice seedling raising substrate with thickness of 2-2.5 cm, and then watering into the rice seedling trays until the water at the bottom of the rice seedling tray reaches the saturation state. The straws are directly used as the soilless straw substrate after being smashed, so that the production processes such as soil fetching and soil sieving are reduced, and the labor intensity of rice growers is reduced.

Description

technical field [0001] The invention relates to a seedling raising method for machine-transplanted rice with a soilless straw matrix. The seedling raising matrix of the method adopts soilless seedling raising. Background technique [0002] The area of ​​machine-transplanted seedlings in Sichuan is expanding year by year, and the area of ​​seedling-raising fields required is also increasing. Machine-transplanted seedling-raising fields require a large amount of plowing layer and fine sandy soil. Year after year, taking soil to raise seedlings will destroy good fields, sandy land, and vegetation. [0003] Sichuan Province is a major grain and oil production area, with more than 19 million mu of corn, more than 29 million mu of rice, more than 19 million mu of wheat, and more than 14 million mu of rapeseed. A large amount of straw will be produced every year, 80% of which are The above straw is burned by farmers in the field, causing a lot of waste of resources and seriously po...
