The fertilizer is a new compound fertilizer developed by the Institute of Soil and Fertilizer of Guangxi Academy of Forestry according to the soil characteristics, growth characteristics and nutritional needs of eucalyptus in Guangxi, using modern science and technology. It has the functions of active soil, water conservation and fertilizer supply.
I. Main components
Mineral nutrients: nitrogen, potassium, phosphorus, calcium, magnesium, sulfur, zinc, boron, copper, etc.
Organic essence: water-soluble humic acid, fulvic acid, amino acids, vitamins and water-absorbing and water-retaining agents, plant growth regulators, fertilizer synergists, etc.
Second, the use method:
The base fertilizer is 0.2kg per plant, which is applied to the border 30cm away from both sides of the plant in about 50 days, and the topdressing is 0.2kg ~ 0.3kg, and the soil is covered. In the future, topdressing 0.4~0.6 kg per plant depends on the growth situation, and topdressing should be far away from the plant, corresponding to the extension point of the crown.
Third, the functional characteristics:
1, improve soil physical and chemical knowledge, improve permeability, enhance water and fertilizer conservation function, dissolve toxins in soil and improve fertilizer utilization rate.
2. It can not only condense and store rainfall moisture in time, but also absorb moisture from the air, thus enhancing drought resistance and making crops wither continuously.
3. Improve the absorption of nutrients and water by eucalyptus, promote cell division and growth, strengthen a series of internal biochemical activities, promote the transformation and accumulation of organic matter in the body, make eucalyptus grow healthily and rapidly, and increase the yield per mu.
Fourth, matters needing attention:
1. Attention should be paid to weeding and controlling underground pests in the early stage of planting, and pesticides for controlling underground pests should be added at the same time when fertilizing every year.
This kind of fertilizer has strong water absorption, so pay attention to sealing and moistureproof.
