Field planting

It can be planted in autumn and winter, and the best planting is from late February to mid-March. The planting holes are all about 80 cm long and 60 cm deep, and each hole is applied with 50- 100 kg of compost or 30 kg of livestock manure, or 5 kg of vegetable cakes and bean cakes, and 30-35 plants are planted per mu. After planting, do a good job of fixing the stem, that is, cut it short above the full bud at 25-30 cm on the trunk.

Fertilize soil or land

Fertilize the young trees. Fertilize 1 time from September to June, and apply imported compound fertilizer100-150g for each plant; Fertilize 1 time in June of the second year, and fertilize 1 time in October of the third year, and then increase the dosage appropriately year by year; From the fourth year, after the crown is initially formed, the fruit tree fertilization method is adopted. Fertilize the fruit trees. Fertilize three times a year, before the first flowering and before the flowering in February; The second time is to strengthen the fruit fertilizer, which is applied at the end of the hard core period and when the fruit begins to expand rapidly; The third time is post-harvest fertilizer, which is applied after the fruit is harvested in the middle and early July. For trees with a yield of more than 50 kilograms, 2-3 kilograms of cake fertilizer or about 50 kilograms of manure are applied to each tree throughout the year. At the same time, we should pay attention to the fruiting year of fruit trees, fertilize before the year, and fertilize in the next year until the soybeans are big. Pothole-shaped (young trees) and annular ditch-shaped fertilization (adult trees) were used.

Plastic trimming

The natural tree shape of Dongkui Myrica rubra is round or oblate. After planting, cut the trunk at the height of 60-70cm, select the trunk to grow healthily, 3-4 buds are evenly distributed as main branches, the distance between main branches is kept at 15-20cm, and the opening angle is 45-60 degrees, so as to cultivate an improved trunk type of "one stem with three main branches". The growth of autumn shoots and late autumn shoots should be effectively controlled after the crown is formed. When the crown grows to more than 2 meters high, it should be capped to keep it at about 3 meters. Too long branches should be cored and broken, and dense, thin and overgrown branches should be appropriately deleted. In the fruiting period, it is generally required that the upper, lower, inner and outer branches of the crown are evenly distributed and ventilated and transparent.

It is best to carry out winter cutting at the end of 65438+February, which is beneficial to the regeneration of branches and the improvement of disease resistance. Generally, the method of "flat cutting" is adopted. This method is simple, the branches are evenly distributed after cutting, and it is easy to form new fruiting branches. Diseases and insect pests, drooping branches, cross branches and weak branches must be cut off to improve the ventilation and light transmission conditions between branches and make the crown form an umbrella or plane shape.

Eliminate pests and diseases

Compared with other fruit trees, Myrica rubra has fewer pests and diseases. According to our observation, they are mainly debt-dodging moths, but so far, they do not pose any harm.

courage

Myrica rubra generally ripens from early June to July, and the fruit is easy to rot and fall off after ripening, so it should be picked in time. And pay attention to light picking, light putting, light picking, and grade the fruit at the same time. Harvesting should be done in the early morning or evening, not after rain or after rain in Chu Qing, otherwise the fruit is rich in water and easy to rot. At the same time, the fruits are pre-cooled in the cold storage after picking, and then packaged.
