Air sac method blanching culture technique for water cress and air sac therefor

Abstract

The invention discloses a cultivating technique of air-pocket tempering the Oenanthe stolonifera, comprising the following steps: 1.soil working- do soil working in dry field for making furrow, employing wide furrow and narrow ditch, making shallow and horizontal ditch on the furrow surface; 2. seeding- seeding Oenanthe stolonifera in the ditch; 3. tempering-tempering the Oenanthe stolonifera when it grows to the target height, with the detail steps as follows: putting the air-pocket in the empty line between the near Oenanthe stolonifera, filling air to the air-pocket, constructing balk around the furrow to Oenanthe stolonifera sprout outside the furrow; 4. recovering- recovering the Oenanthe stolonifera when it reaches the tempering effect, with the steps as follows: ejecting the air out of the air-pocket and taking up the air-pocket, cutting off the Oenanthe stolonifera from the root area with knife, cleaning the plant. The air-pocket for Oenanthe stolonifera tempering is made of tubular black high-pressure polyethylene film with a certain length, and a gas charging valve is equipped in one end of the air-pocket.

Description

technical field [0001] The invention relates to a softening cultivation method of watercress and a tool used for softening cultivation of watercress. Background technique [0002] The quality of watercress cultivated through shading and softening is significantly improved. The watercress cultivated by dry farming in our country adopts the method of cultivating soil to achieve the effect of softening the product, that is, when preparing the land for dry farming and making furrows, reserve the space between the two furrows according to the amount of soil taken; When the cress seedlings grow to the target height, the soil in the gap is filled in the empty row between two rows of cress in stages or at one time, so that the middle and lower parts of the cress seedlings can be shaded and moisturized, and the tender stems and leaves are gradually transformed. It is white or light yellow, so as to grow into the target product. [0003] After the target product grows, the product m...

AI Technical Summary

Problems solved by technology

[0005] 1. A large amount of labor is required, especially the filling and digging of soil, harvesting and cleaning are all manual operations;

[0006] 2. The labor intensity is high, and the filling volume of cress per hectare is generally more than 1,500 cubic meters;

[0007] 3. It is very difficult to clean the product. The softened young cress seedlings are covered with a lot of wet soil, which is difficult to clean;

[0008] 4. The land utilization rate is low, and the planting area of ​​common cress only accounts for about 60% of the total area
