Winter is one of the important periods for seedling production. In winter, most of the above-ground seedlings are dormant, but the growth of the underground parts and the nutrient metabolism activities in the tree will continue. To do a good job in winter management is related to the growth of seedlings in the following year. As far as the current situation is concerned, the management of nursery stock must focus on the following two points:
1. Draining water and lowering the groundwater level In the winter, the ground water evaporates slowly and the water requirement for the seedlings decreases. If there is too much water in the soil, the soil will be poorly ventilated, which will easily lead to lack of oxygen in the roots, difficulty in breathing, and even suffocation. Therefore, we must do a good job of trenching and drainage so that the trenches can communicate.
Second, the removal of deciduous weed deposits to the winter, weeds withered, dry branches, leaves increased, these deposits provide pests parasitic, breeding provides favorable conditions, especially in some diseased branches, diseased leaves and pathogens Parasites. These residual pathogens and parasites multiply in the winter and spread as soon as the spring time, making it difficult for the production and management of seedlings. Therefore, it is necessary to remove defoliation and weed accumulations.
Third, to give up enough to apply fertilizer? Winter seedlings enter the dormant period, then apply a good wax fertilizer is conducive to the accumulation of nutrients seedlings, to lay a solid foundation for the growth of the following year. Fertilizers are well-established organic fertilizers. The fertilization time is generally at the end of December, and the dosage depends on the size of the seedlings.
Organic powders are becoming a popular trend demanded by consumers, it is lower pesticide residue, minimal chemical composition and more healthy.
Organic powder can be widely used in food, beverage, cosmetic, medicine and health care.
