Problems solved by technology

[0004] Now the mechanical sowing and transplanting techniques of crops are relatively mature, especially in rapeseed, tobacco, rice and other crops, but cotton cannot be transplanted by mechanized seedlings, which has a lot to do with the backwardness of the traditional cotton seedlings. , that is, agronomy and agricultural machinery are not integrated. The cotton seedlings raised by the current seedling raising methods are not suitable for machine transplanting. It is necessary to develop new cotton seedling raising technologies as soon as possible to adapt to cotton mechanical transplanting.

Embodiment 1

[0036] 1. Make seedling paper tubes with an inner diameter of 3cm, a thickness of 0.05cm, and a height of 10cm, and glue the paper tubes to each other to form a combination of 400 seedling paper pots.

[0037] 2. Knead and pulverize the crop straws into particles ranging in size from 0.1cm to 2cm, and send them into the straw puffing machine for puffing and pulverization.

[0038] 3. Get the crushed and puffed stalk mixed with xanthan gum in a ratio of 1% by weight, then send it into the feeder, and evenly add it into the hole of the seedling-raising tube with the feeder, and stop when adding to the depth of the hole of the seedling-raising bowl.

[0039] 4. Take the crushed and puffed stalk and mix it with perlite for seedlings in a volume ratio of 7:3, and add 0.5% FA and starch grafted water-retaining agent and 0.2 % substrate wetting agent, sent in the feeder, the feeder is used to add the base material into the hole of the seedling raising tray, solidify it while feeding,...

Embodiment 2

[0044] 1. Make a seedling paper tube with an inner diameter of 2cm and a height of 13cm, and glue the paper tube and the paper tube to each other to form a combined seedling pot with 400 holes. The bottom of the seedling pot is supported by cardboard. Drill 400 holes with a diameter of not less than 1 mm to remove excess water in the paper pot. The paper tube combined seedling pot is surrounded by hard boards. The height of the hard board is 1 cm higher than the upper opening of the paper tube to prevent the finished seedling tray filled with the substrate. It was crushed and deformed during storage and transportation.

[0045] 2. Knead and crush the crop straws into particles ranging in size from 0.1cm to 5cm, and send them into the straw extruder for puffing and crushing.

[0046] 3. Take the crushed and puffed stalk and mix it with vermiculite for seedlings in a volume ratio of 1:1, and add bio-organic fertilizer, starch grafted water-retaining agent and 0.2% sodium hypochl...

Embodiment 3

[0051] 1. Make a seedling paper tube with an inner diameter of 5cm and a height of 15cm. Bond the paper tube and the paper tube to each other to form a combined seedling pot. The bottom of the seedling pot is supported by cardboard. Paper tube combined seedling trays are surrounded by cardboard enclosures, and the height of the cardboard around the enclosure is 1cm higher than that of paper tube seedling trays, which is convenient for stacking of finished seedling trays filled with matrix, and prevents finished seedling trays filled with matrix from being stored in storage And it was crushed and deformed during transportation.

[0052] 2. Take peat for seedlings, add cotton seedling special root-promoting fertilizer, starch grafted water-retaining agent and 0.2% matrix wetting agent according to the weight ratio of 1% peat, and send it into the feeder, and use the feeder to add the base material into the seedling pot In the hole, solidify while feeding, and stop when it is 1cm...

Abstract

Seedling raising and transplanting in protected areas can prolong growth period by 30-40 days and promote increase of cotton yield. Traditional seedling raising and transplanting use soil nutrition pots. Manufacturing and transplanting of the soil nutrition pots are labor-consuming, high in labor intensity and low in efficiency. Paper-tube combined filled lightweight substrate and industrially made nutrition pots are used, mechanical seeding and mechanical transplanting are carried out and are development trends of cotton industry in China.

Description

Technical field [0001] The invention relates to a cotton cultivation method and belongs to the field of agriculture. Background technique [0002] Cotton seedling transplanting in protected land can prolong the effective growth period of 30-40 days compared with direct-seeding cultivation, that is, the flowering and bolling period is prolonged, so seedling-raising and transplanting can increase the yield of cotton by 15% to 20% compared with direct-seeding cultivation. For this reason, the Yangtze River Basin and the Yellow River Basin Cotton planting adopts the method of raising seedlings and transplanting. At present, cotton seedling transplanting has been using the traditional soil nutrition pot seedling transplanting method. The steps of bed soil preparation, pot making, seedling raising, seedbed weeding, seedling disease prevention, potting, and transplanting cannot be operated by machinery and need to be done manually. Finished, the nutritional bowl is labor-intensive...
