Embodiment 1
[0038] refer to figure 1 , a method for squatting seedlings for open-field cultivation of Chinese chives, comprising the following steps:
[0039] S101: Enter the squatting seedling stage, judge whether to enter the squatting seedling stage according to the season, weather, geographical location and the height of the leek seedlings; if the season is winter, the weather is cold, it is located in a high altitude area and the leek seedlings are 5-10cm high, enter the squatting seedling stage;
[0040] S102: Fertilize, repair drainage and irrigation ditches, weed and level, evenly spread fertilizer with a thickness of 0.2-2cm around each cluster of leek seedlings; the mass ratio of fertilizer is 60%-80% of decomposed farmyard manure and 10% of dry fine soil ~15%, phoxim granules 5%; among them, phoxim granules can prevent leek maggots, and the planting area of leek seedlings can be leveled and used as a furrow, with a width of 1.2-1.5m and a length of 7-10m, which is easy to man...

Abstract
The invention discloses a seedling hardening method for open field culture of Chinese chives, and belongs to the technical field of seedling hardening of Chinese chives. The method comprises the following steps of: Step 101: entering a seedling hardening period, and judging whether to enter the seedling hardening period according to the season, the weather, the geographic position and the seedlingheight of the Chinese chives; Step 102, performing fertilization, trimming drainage and irrigation ditches, performing weeding and leveling, and uniformly spreading fertilizers at the thickness of 0.2 to 2 cm around each cluster of Chinese chives; Step 103: in the early period, performing slight watering once respectively in the morning and evening, shallowly loosening the soil once every two days, performing topdressing according to the growth condition of the seedlings of the Chinese chives in the soil loosening process, and enabling the topdressing amount of per cluster of seedlings of Chinese chives not to exceed 50 g until the seedling height of the Chinese chives is as high as 10 cm; and Step 104, performing once intertillage. Multi-time intertillage is performed; earthing-up is performed after the intertillage; the root system growth of the Chinese chives is promoted in a mode of cutting away excessive unnecessary leaves and mixing the unnecessary leaves into the soil to be compacted; the quantity of unnecessary roots and unnecessary leaves is reduced; the operation work procedures in the seedling hardening period is reduced; and the survival rate of the Chinese chives andthe quality of the Chinese chives are improved.
Description
technical field [0001] The invention relates to the technical field of leek seedling squatting, in particular to a method for squatting leek seedlings for open-field cultivation. Background technique [0002] A traditional crop management technique. Technical measures for inhibiting excessive growth of stems and leaves of seedlings and promoting root development in crop cultivation. Its function is to train seedlings, promote plant growth and robustness, improve late-stage stress resistance and lodging resistance, coordinate vegetative growth and reproductive growth, and control fertilizer and water at the seedling stage to make the internodes of the plants tend to be thick and strong and the root system developed. In addition, multiple times of intertillage can cut off capillary water in the soil on the one hand, make the surface soil loose and dry, keep the water in the lower layer well, and facilitate the root system to elongate in depth; The metabolic level of nitrogen...
