The latest course of high-yield cultivation techniques of fertile mandarin

Wo orange is a hybrid of "Temple" orange and "Danxi" red tangerine. it is a late-maturing hybrid citrus variety with strong growth potential, natural round head shape at the beginning of the crown, and then it opens gradually. in the production, you can choose fragrant orange, red orange, trifoliate orange and citrus orange as rootstock, there is grafting incompatibility with citrus grapefruit, avoid choosing citrus grapefruit as rootstock, let's take a look at the high-yield cultivation techniques of mandarin orange.

Yield performance of fertile mandarin

The fertile mandarin mainly takes the early autumn shoot as the fruiting mother branch, and the fruiting shoot is mostly leafy flower branch, and the fruit setting rate is higher in the middle and lower part of the crown. The grafted seedlings of "fertile mandarin" on Fructus Aurantii rootstock began to test flowers after 3 years of planting. The plant yield reached 51kg in the fourth year and 19.7kg in the fifth year. In the second year, the yield per plant was between 3.4kg and 10.4kg, and the yield per plant in the third year was 17.2kg and 1400 kg per mu, respectively.

Preparation of mandarin saplings

When cultivating fertile orange, it is necessary to ensure that the plant type of fertile citrus seedlings is good and the root system is intact, especially without carrying the pathogens of quarantine diseases such as citrus Huanglong disease, canker disease, decline disease and so on. Ziyang orange, sour orange and red orange are the main rootstocks in dry sloping land or alkaline soil, and big-leaf Fructus Aurantii is used as rootstock in paddy field.

Garden soil tillage

Choose loose, fertile, good drainage and irrigation, leeward to the sun or paddy field to build a garden, and those with a small slope can use a large horsepower tractor with a single plow to carry out deep ploughing in the whole orchard, ploughing the field in the direction of contours or vertical roads when the soil moisture is low, ploughing at a depth of 60cm to 70cm, and then raking once or twice to level off. Then, according to the drainage condition of sloping land, flat land or paddy field, dig the drainage ditch with hook machine. You can also use a large hook machine to hook the whole park at a depth of more than 60 centimeters, and then rake it flat. Or dig the planting pit 1 meter wide and 0.6 meters deep, put 50 kilograms of retted organic fertilizer and 1 kilogram of calcium superphosphate mixed with the soil and return to the pit, the soil is higher than the ground.

Planting technique of fertile mandarin

The main results are as follows: 1. Planting density: the planting distance of fertile mandarin is 230m, the row spacing is 340m, and 56110plants per mu are planted, which can be selected according to planting preference and management level.

2. Planting time: the planting time of fertile mandarin is from February to early May, when the temperature rises, when there is more rainfall or when it is cloudy, it can also be planted from September to November, when it rains or when it is cloudy, and container seedlings can be planted throughout the year.

3. Planting method: the bare root seedlings of Wo Citrus can be soaked in 0.1% potassium permanganate solution for about 2 minutes, and then rinsed with clean water for about 3 minutes, which can kill the bacteria on the surface of the plants. then soak the roots of Wo Citrus seedlings in sterilization, insecticidal, nutrient solution and other solutions for about 8 hours, take out the seedlings and stick to the yellow mud hit by this solution.
