First, the cultivation method of red beauty citrus
1, planting time
Red Beauty Citrus can be planted from September to April 15, but 9- 10 is the best. Choose land with warm and comfortable environment, fertile soil and good drainage when planting. Red beauty likes sunshine, and sunny, warm and comfortable areas are conducive to the growth of red beauty.
2. Planting density
The plant spacing of Red Beauty citrus is 2.8m, and the row spacing is 3m. It is advisable to plant 70 ~ 80 plants per mu. Determine the size of the pit according to the size of the plant. Generally, the pit position of 3-year-old seedlings is 50*50*50cm, and the pit position in hilly or mountainous terrain can be appropriately increased.
3. Soil consolidation
Red beauty citrus has strong adaptability to soil PH value, ranging from 5.4 to 8.5, with 5.6 to 7.2 being the most suitable. The salt tolerance of fruit trees is 0. 14 ~ 0.20% of the total soil salt content, and the hazard limit is 0.30%. Before planting acid soil, soil improvement must be carried out, so that the soil is improved first and then seedlings are planted.
4. Planting method
It is best to apply foot fertilizer (the best base fertilizer is decomposed organic fertilizer or compost, plus appropriate amount of phosphate fertilizer) before planting red beauty citrus, mix the base fertilizer with the soil in the planting hole, cover it with a layer of soil, and then plant it. It is suggested to use two-year-old seedlings for planting. In this way, the seedlings are not easy to be covered by weeds, the survival rate is high, and they can bear fruit one year in advance.
5, planting points
When planting red beauty citrus, we should plant strong seedlings with straight roots and uniform distribution, and then cover the root neck with fine soil in layers, and the root neck is about 10 ~ 20 cm higher than the surrounding ground (so that the seedlings can be planted on small mounds). Build a small ridge around the seedlings, and immediately pour water into the ridge after planting.
Second, the management method of red beauty citrus
1, young trees are fertilized
Generally, pre-bud fertilizer is applied to Hongmeiren citrus in early March, and 50 grams of ternary compound fertilizer and 25 grams of urea are applied to each hole 30-40 cm away from the trunk. Conditional, it is recommended to use water-soluble fertilizer (generally diluted to 200 times) for irrigation.
Hongmeiren citrus was applied with strong bud fertilizer from May to June, and ternary compound fertilizer100g and urea 50g were applied to each hole. From August to September, apply ternary compound fertilizer150g and urea100g to each hole 50cm away from the tree tray. After 10 months, fertilization should be stopped to avoid sprouting new buds (easily damaged by frost) and causing nutrient loss of trees.
2, plastic pruning
After one year's planting, the citrus seedlings of Hongmeiren should be pruned by opening the window, properly cutting off the main branches and secondary branches, cutting off too many and too dense branches and diseases and insect pests, so as to improve the lighting and ventilation conditions. In order to improve the quality and keep the tree strong, flowers should be thinned after germination and before flowering, and leafless inflorescences on twigs should be thinned in time. The first fruit thinning was carried out in late June, and pests, abnormal fruits and over-dense fruits were eliminated. Carry out the second fruit thinning in August-September to remove cracked fruits, diseased fruits and branched fruits.
3, hanging fruit trees for fertilization
At the beginning of March, pre-bud fertilizer was applied to Hongmeiren citrus, and ternary compound fertilizer 1.0 ~ 1.5 kg could be applied to each plant (each plant was divided into 5 ~ 6 holes). According to the number of fruits, 500 grams of urea can be added to each plant. From May to September, apply 1 time of fruit-strengthening and expanding fertilizer every 40 days, and each plant can apply 500g of ternary compound fertilizer and 50g of potassium sulfate.
From June11-June 65438+February, the post-harvest fertilizer was applied, and 30 ~ 50kg of decomposed farmland soil miscellaneous fertilizer was applied to each plant. If conditions permit, it is best to mix some oil cake fertilizer. Red beauty has a great demand for fertilizer and water, so it is necessary to dig a reservoir in advance to provide sufficient water for fruit trees in autumn, otherwise it will be difficult to obtain high-yield and high-quality fruits.
The above is a brief introduction to the cultivation methods of red beauty citrus. Red citrus has high sugar content, low acid content, seedless, instant in mouth and excellent taste. It can be planted in the open air or in the greenhouse, but it is recommended to cultivate in the greenhouse with frost.
