Seedlings, fill seedlings, Dingmiao timely seedlings from the seed germination to Dingmiao, the general seedling age of about 18 days, during which should be repeated multiple seedlings. The seedlings were unearthed for 3 days for the first time. The seedlings were separated and 4-5 leaves were planted for the second time, leaving 2-3 plants per hole. According to the strength of the seedlings, leaving strength to weak, when the leaves grow to 8-9 leaves, according to the spacing of about 50 cm from the planting seedlings. The timing of seedlings should be controlled at high temperatures in the noon. Due to the different ability to adapt to the environment, some weak seedlings and diseased seedlings show their morbidity and are easier to identify and eliminate. If there is a shortage of seedlings, it should be replanted promptly.
The cultivation of weeds and weeds is carried out in the middle of Dingmiao and Rosettes respectively. According to the principle of "shallow, double, deep, and triple without damaging the roots", the cultivation of high ridges should follow the principle of "deep sewers and shallow rakes." Cultivate the grass and cultivate the soil, such as the late rosette overgrowth, can be seedlings.
Water-based topdressing, such as the use of less fertilizer, can be used to recover a fertilizer at the seedling stage. Mushi urea 10 kg. In the rosette period, the beginning and the middle of the ball stage, each fertilizer is chased once, and 15-20 kg of urea is applied per mu, which is a combination of foliar potassium dihydrogen phosphate and urea sprayed once every 10 days. Watering should be carried out in conjunction with topdressing. The soil in the early stage of the ball is dry and wet, and the soil is moist during the ball stage. Stop watering until 10-15 days before harvest to facilitate storage.
