1, Perfume lemon pit planting
Planting plant spacing of 3 * 2.2 meters. Before planting, cut the leaves appropriately, use rooting agent mixed with yellow mud slurry good root, fill with fine mud and compaction, pour enough rooting water, cover the tree plate with moisturizing.
2, perfumed lemon fertilizer management
Perfumed lemon because of the root system belongs to the plant, fertilization is best to light fertilizer diligently as well as composted organic fertilizer liquid is good, both slightly acidic, in order to facilitate plant absorption, but also will not burn the root system. Young trees after planting the first year and the second year of nitrogen fertilizer for fertilizer, to promote the formation of the crown, but later to control nitrogen fertilizer, increase the application of calcium, magnesium and phosphorus compound fertilizer. Autumn organic fertilizer as a base fertilizer, combined with the growing period of extra-root fertilizer, to strengthen the tree nutrients, to promote the formation of flower buds and blossom and fruit.
The perfumed lemon fruit tree fertilization focuses on after the flower to fruit expansion and the autumn tips of the twitching period. Fertilizer can be applied ripe bran fertilizer or human manure, and combined with the growth of frequent application of urea and phosphorus and potassium fertilizer. Fertilizer using thin fertilization method, that is, many times, a small amount, in order to prevent the loss. Lemon is not drought tolerant to timely drenching or irrigation.
If you apply chemical fertilizers, you can dilute the compound fertilizer about 20 times watering, but can not be used every time you water, to 10 days or so as appropriate. Can also be used in solid organic fertilizer or granular chemical fertilizer hole in the pot, but the amount should rather less than more, to 400-type pots each time the application of organic fertilizer 200 grams or so, about 30 grams of chemical fertilizer can be.
3, perfumed lemon plow weeding
In the summer and fall dry season, to plow before the drought, to keep the soil loose, reduce water evaporation. Summer can be planted between the rows of fruit trees leguminous green manure for mulch, to prevent soil erosion, weeds under the canopy should be eradicated, and weeds on the canopy to mulch.
4, perfume lemon pruning
Perfume lemon young trees grow vigorously, flowering strong, in pruning at the right time light should not be heavy, more branches and leaves, in order to be able to penetrate the canopy into a small amount of sunshine as a principle. Spring, summer, fall, mainly on the long branches in time to pick heart or short cut. In winter, the main cut off pest branches, dead branches and fruiting branches.
5, perfume lemon flowers and fruits
Lemon has a strong growth characteristics, the results of the tree can be used to cut off the roots, water control, branch ring cutting and other means of controlling strong growth. Can also be used in the pre-growth of polyoxazole 500 times liquid spray 2 to 3 times, inhibit the growth of branch tips, or in September to October before the old maturity of the fall spray, to promote the formation of flower buds. The fruiting trees can be applied to the full bloom 20 days before the rotted bran fertilizer water 10 to 15 kg and phosphate fertilizer 1 to 2 kg; shed flowers 3/4 and young fruits after the emergence of fertilizer should be carried out outside the root, available 0.3% urea + 0.3% potassium dihydrogen phosphate; or 0.3% urea + 5 to 7 mg / liter of 2,4-D solution; or with 50 mg / liter of Qibao "nine two 0 "Crown spraying, every 20 days, spray 1 time, 2 to 3 times in a row can significantly improve the fruiting rate. Boron deficient orchards can be sprayed in the flower bud differentiation 0.1% to 0.2% borax, after the flowers and then spray 1 time. In the event of continuous rain in the spring, pay attention to shaking the petals off, accelerate the young fruit to green, and can prevent leaf roller moths and other harm to young fruits.
6, perfumed lemon pest control
Citrus rheumatism: the disease is prevalent in April to October, with high temperatures and rainy and humid conditions are the most rampant. It mainly harms the trunk, but also the main branches, the diseased cortex becomes brown, watery, often cracked and glue, leaf yellowing and shedding, tree decline. Prevention and control methods: pay attention to prevent orchard waterlogging, reduce orchard humidity; increase boron fertilizer, can take foliar spray and inter-root drenching, foliar spray concentration of 0.3%, inter-root drenching will be borax mixed with animal feces into the soil; remove the source of the disease, combined with pruning in the early spring, cut out the pests and insects withered branches, digging out the dead tree centralized burned to reduce the source of the disease.
