1. Proper management should be carried out in the seedling stage

Thinning and supplementing seedlings

Seedling mending is usually started after cotyledons grow out and when 1 to 2 pairs of true leaves grow out. If it is too late, it will easily make the seedling very fragile. Generally, the seedlings are kept according to the triangle, and the distance between each plant is about 15 cm

Thinning method

The weak seedlings are generally removed, leaving the ones that grow better, and the ones that grow too dense should be thinned out. Thinning seedlings can generally be carried out at one time, of course, it can also be completed many times. It usually starts when the soil is soft after watering or after rain. When operating, be careful not to hurt the seedlings nearby. At the same time, go out to the weeds, and then carry out appropriate suppression and watering, so as to tightly connect the roots of seedlings with the soil

2. Watering and topdressing

If it is the planting method to cultivate White Du, it should be determined according to the soil conditions if it is watered. The amount of water should be appropriately reduced before a part of true leaves grow on the ground and the seedlings grow rapidly. Squat seedlings. After squatting the seedlings, you can water them two to three times. In the rainy season, the amount of watering should be determined according to the amount of rain. After the growth period, you should start to reduce the number of watering

Pour it again in November to prevent cold water. In addition, we can add fertilizer 2 to 3 times according to the watering. A little nitrogen fertilizer can be added in front of the seedling growth period, which can promote its better growth. In the later stage, a little phosphorus fertilizer and potassium fertilizer can be added, which can make the seedling more lignified

If it is Baidu that survived cutting, watering must be timely. Generally, it is necessary to keep the seedbed moist after cutting. The seedlings should be watered with small water and clear water, but it is not possible to irrigate with large water. Topdressing is to add quick acting fertilizer after cutting for 40 days, so that it can grow more healthily
