Citrus young trees grow mainly, mainly to develop well-developed absorption root groups, improve the absorption capacity, promote the root system to absorb sufficient water and nutrients, supply buds shoots need to make buds more buds, shoot more shoots strong, speed up the crown formation, Early flowering results, achieve early end of high yield. The measures are as follows:
Deep application of heavy fertilizers, rooting deep. Citrus juvenile trees are usually given two heavy fertilizers a year, digging deep trenches, and mainly organic fertilizer. Generally in the summer, there is much rain, high humidity, and when the weeds are abundant, it is applied once. In the winter, shoots are old and mature, and the plants stop growing before they are applied. When fertilizing, dig deep 50 to 60 centimeters deep, 30 to 40 centimeters wide, and 80 to 100 centimeters deep in the east-west and north-south directions at a place 50 to 60 centimeters from the juvenile tree of citrus. In the deep trenches, 25 to 30 kilograms of various weeds, 8 to 10 kilograms of livestock and poultry manure, or 1.5 to 2 kilograms of bio-organic fertilizers are used to mash up. Weeds are applied on the bottom of deep trenches, and the fertilizer is mixed and mixed evenly with the soil excavated from digging deep trenches, and then filled back into deep trenches so that various weeds can be buried under pressure.
Diligent application of thin fertilizer, a small number of times. On the basis of deep application of heavy fertilizer, the citrus young tree will be applied twice for each new shoot. The complete NPK fertilizer is the main fast-acting fertilizer. Leaf, leaf size is basically stereotyped, when the leaf color is light green. Apply 80-100 g of water-soluble fertilizer (20-20-20) per plant per plant, apply 5-6 kg of decomposed human or animal manure to fresh water or biogas slurry, or even apply it to the top soil under the canopy. It is advisable that the fertilizer solution completely penetrates into the soil without flowing out. Or apply 150-200 g of potassium sulphate (15-15-15) potassium sulfate or nitrate-sulfur or pure sulfur-based compound fertilizer to each plant, and dig deep and wide each 25 to 30 centimeters around the canopy drip line. Shallow ditch, spread the fertilizer evenly in the ring shallow ditch, cover the soil, cover the fertilizer can live. With the continuous growth of young citrus trees, the amount of fertilizer is gradually increased to meet the needs of growth and development.
Foliage dressing, add nutrients. On the basis of top-dressing, it is necessary to top-dress the leaves several times to supplement various nutrients. In general, once every 10 to 15 days, foliar spray 0.1% magnesium sulfate, 0.1% zinc sulfate, 0.2% urea, 0.3% potassium dihydrogen phosphate, and 600 times amino acid compound micronutrient fertilizer to uniformly wet all branches and leaves. Dropping drops of water is appropriate.
