Citrus cultivation techniques of Hongmei

Red Beauty is a hybrid variety of citrus, which has sweet orange-like aroma, high sugar content and high planting efficiency. What is the citrus cultivation technique of Hongmei?

Citrus cultivation techniques of Hongmei

The main results are as follows: 1. the planting land requires fertile soil, good drainage and irrigation capacity and sufficient light. The cold resistance of Hongmei is poor, and it has higher requirements for heat, light and fertilizer. It is sensitive to soil moisture content. It needs to choose places convenient for drainage and irrigation to plant, and to reasonably control water according to the actual situation, control diseases and insect pests and improve quality.

2. The land should be fertile, and the soil layer should be more than 50 cm. Avoid in the stone land; drainage should be unobstructed, the groundwater level should not be higher than 60 cm; the water supply should be convenient, avoid in the low-lying land; choose the south side of sufficient light and winter south, avoid in the tuyere, strong wind land; avoid places that are susceptible to freezing; must be places where there is no history of Huanglong disease, canker disease, broken leaf disease and atrophy disease.

3. When preparing the soil, it is necessary to apply sufficient basic fertilizer, row spacing to pick up trenches, trenches 100cm wide and 70cm deep, and press straw, weeds, compost, sheep dung, bacterial agent or bacterial fertilizer into the trench, with a pressure of 15000 jin-20000 jin per mu; cover the dug soil for 90-100 days and then mix the soil with the substrate. Dig holes when planting, and sprinkle 200 jin of lime or gypsum around the hole plate.

4. Choose virus-free seedlings with developed root system, strong growth and pure varieties. In terms of seedling age, one-year-old or perennial seedlings can be selected according to their own investment cost. The bigger the seedling ridge, the higher the price.

5. When planting, it should not be too deep, nor too shallow, too deep. When the soil touches the grafting interface, it is easy to cause germs to invade and lead to rotting at the base of the rhizome; too shallow, the root system can not fully contact the soil, can not slow down seedlings and take root quickly. When setting the value, it is best to mix the surrounding soil with sand, return the soil carefully to avoid damaging the root system, and put a layer of sand on it. It is generally recommended that the distance between rows and plants is 4 meters × 3 meters.

6. if you buy new seedlings and observe the growth of the root system, the abnormal root should be cut off below the abnormal root, and the straight root should be cut off the tail of the main root. Trunk 30-40 cm high pruning, base 20 cm below sprouting erased to promote branching.

7. Using happy shape or round head shape, the main purpose of the young tree stage is to enlarge the crown, cultivate backbone branches and increase the leaves of crown branches. One year after planting, the trees should be pruned in time, the effective fruiting branches should be cultivated, and the extended branches of main branches and secondary main branches should be cut properly to maintain a certain amount of growth and tree potential. The adult fruit trees should be pruned mainly in spring, combined with the whole year.

8. Red beauty young trees are mainly nitrogen fertilizer and organic fertilizer, following the principle of frequent application of thin fertilizer, applying budding fertilizer before spring shoot germination, mainly quick-acting nitrogen fertilizer and potassium fertilizer, combined with sea elf biological stimulant root system, in order to awaken the root system and promote new shoots. In July, strong fruit fertilizer was applied, organic fertilizer, balanced compound fertilizer, medium and trace element fertilizer and sea elves biological stimulant were applied to achieve the purpose of strengthening fruit, promoting shoots and raising roots. 10-15 days before fruit harvest, the main compound fertilizer is quick-acting compound fertilizer in order to restore the tree potential quickly.

9. in management, in addition to pruning to improve the fruit-setting rate, it is also necessary to thinning flowers and fruits and bagging. Flower thinning is carried out from budding to flowering, mainly to remove the leafless inflorescences on the weak branches and the leafless inflorescences on the weak branches. Fruit thinning can be carried out twice, the first time in late June, to remove disease and insect fruit, deformed fruit, damaged fruit and crown bore too much, too dense fruit. The second time is from August to September, the dehiscent fruit, disease and insect fruit, small fruit and tip fruit are removed. Bagging is carried out from August to October, and bagging the remaining fruits can effectively prevent diseases and insect pests. Pest control should be carried out before bagging, and white transparent paper bags should be used as bagging materials, and the mouth of the bag should be fastened when bagging. Take off the bag 10 days before harvest, which is beneficial to coloring and improving the merchandise.

10. There are many diseases and insect pests in citrus fruits, so we should pay attention to the principle of prevention and the combination of prevention and control. First of all, it is necessary to strengthen cultivation management and improve tree resistance. Secondly, we should pay close attention to the work of clearing the garden in winter and reduce the base of diseases and insect pests. In the use of agents, try to use high efficiency and low toxicity, and use alternately to protect natural enemies.

Red beauty citrus cultivation techniques are introduced here, I hope to have a certain reference value for everyone.
