For cedar seedling farmers, raising their survival rate is the first consideration, so when using seedling containers to raise seedlings, how can we do it? Under what circumstances is it more suitable for seedling raising? Now let's briefly introduce:
First of all, fertilization usually begins in mid-June and requires topdressing once a week or so. The types of fertilizers include ammonium sulfate, calcium superphosphate or nitrogen, phosphorus and potassium compound fertilizers. When the top dressing is applied, it is best to spray seedlings with diluted fertilizers. Fertilization will be stopped after mid August. Then there are interval seedlings, cedar seedlings unearthed, in order to cultivate more quality seedlings of cedar, we have to leave ample living space for the cedar, which requires us to carry out interval seedlings, interval seedlings generally in June, each container left a strong seedling or two.
There is also the fact that the seedlings of Cedar have developed main roots, few lateral roots, large area of afforestation, and a large number of seedlings used. And there are some high-yielding forests in the afforestation land, traffic is not convenient enough, therefore, the seedling container of Cedar should be selected according to the principle of small size, convenient transportation, but does not affect the growth of seedlings. . It is more suitable for low mountain and hilly land far away from residential area. Generally, it is near the water source at the foot or mountainside of afforestation. We should choose nursery land with better soil structure and fertility, loosen soil, beating, silicate and base brick in situ. We should pay attention to this kind of situation, which is more suitable for cultivating Centenary seedlings of Cedar.
