After the seedlings emerge and time the seedlings to prevent the seedlings from growing too densely and developing slender and weak. When the seedlings are 6 to 10 cm high, set the seedlings and sow one seedling at 7 to 10 cm. If there are any missing seedlings, the large and strong seedlings should be transplanted with soil. It is best to transplant on a cloudy day to avoid transplanting when the sun is strong. conduct.

Take as much original soil as possible when transplanting seedlings, and water them in time after replanting to facilitate the survival of the seedlings. For hole sowing, leave 1 clump of seedlings (3 to 4 plants) every 15 to 20 cm. In fields sown by broadcast, keep the distance between plants at 10 to 13 cm.

2. Cultivating and weeding.

Incorporate cultivating and weeding when thinning out seedlings. The first time, only shallowly hoe the topsoil to avoid overwhelming the seedlings; the second time, you can dig deeper. In the future, depending on whether the soil is compacted and how many weeds there are, cultivate and weed 1 to 2 times, and build a little soil at the base to maintain fertilizer and solidify the seedlings.

3. Top dressing.
