How many times a year do figs bear fruit? How to plant high yield?

Fig, also known as milk berry, is a common economic fruit tree in China. It is very popular because of its high edible value and ornamental value. How many times a year do figs bear fruit? How to plant high yield?

How many times a year do figs bear fruit?

Figs generally bear fruit twice a year, that is, summer fruit and autumn fruit. Although figs are deciduous fruit trees, they like warmth and have weak cold tolerance. In the areas with low temperature in winter and late frost in early spring, it is easy to produce frost injury, or even the whole plant withered. Therefore, it is necessary to consider the local temperature in winter and overcast and rainy weather in summer, and only by taking corresponding preventive measures against meteorological disasters can we ensure the high quality and high yield of figs. Whether there is fruit or not should be related to the age of the tree, the adequacy of nutrient supply and the planting environment.

Planting method:

I. Variety selection

There are many varieties of fig trees, with more than 800 varieties. There are more than ten main cultivated varieties in China, which are divided according to their uses, such as processing, greening, fresh food and dual use. According to fruit maturity, there are special varieties of summer fruit, special varieties of autumn fruit, special varieties of summer and autumn fruit, etc. When planting, we can choose varieties with bright color, large and correct fruit, long fruit growth period and good quality, such as Blanrek, Qingpi and Zitofen, etc.

Second, garden land

Fig is a small deciduous subtropical tree, which likes temperature and light. In the selection of planting garden, in addition to the factors of sunshine and temperature, the selection of the right soil is particularly important to increase the yield of fig trees. It is suitable for sandy loam or humus loam with deep, fertile and well-drained soil. It can also be planted in the courtyard.

III. Colonization

One-year-old truncated seedlings (10-30cm) are commonly used for planting fig trees in spring and autumn, mainly in spring. Fig rooting requires high temperature (9-10 ℃) and fast growth, so it is suitable for planting before and after Qingming Festival. The planting density varies with varieties and construction methods. generally speaking, the plant spacing of "X" pruning method is 1-2m, the row spacing is 2-3m, and the row spacing of "Y" pruning method is 2m.

IV. Fertilization

The demand for fertilizer in the seedling stage of fig trees is small. After entering the seedling stage to the fruiting stage, the leaves are hypertrophic, the branches are strong, the growth is vigorous, and the fruit load is large, so it is necessary to strengthen the nutrient supply. In addition to a large amount of nitrogen fertilizer, it is also necessary to supplement phosphorus, potassium and calcium fertilizer in time to improve fruit quality. Figs can be fertilized for the first time when the new shoots are flourishing, mainly applying nitrogen fertilizer 210-300kg/h fertilizer. During the period of fig fruit ripening from August to October, three more times of topdressing should be carried out. At this time, compound fertilizer is mainly applied, 240-300kg/h fertilizer can be applied each time.

Fifth, watering

The root system of the drained fig tree is developed, it is easy to get nutrients from the soil, and it is resistant to drought and afraid of waterlogging, so it does not need to be watered frequently. In the dry environment of summer and autumn, it needs to be watered frequently, as well as during the new shoot growth period of fig tree and before overwintering. Figs are mostly planted in spring during the Qingming Festival, Rain Water is more, we should always pay attention to drainage, drainage is not smooth, light leaves, heavy, the whole plant dies. In July and August every year, the rainfall is concentrated, when the fig fruit is ripe, too much water will dilute the sugar content of the fruit, and then affect the quality.

VI. Shaping and pruning

The main tree shapes commonly used in fig tree cultivation are cluster shape, happy shape, source shape and cup shape. The clump shape has no trunk and is in a clustered state with a low crown. When the seedlings were planted, the plants with a height of 10 mi 15 cm should be left in pruning, which was beneficial to the branching at the base, and then 5 branches were selected from the hairy branches as clump main branches for culture. The happy shape has no central trunk, lower trunk and larger crown, and generally has 3 main branches and lateral branches.

Fig tree pruning is mainly concentrated in two stages, growing season and winter pruning. The branching force is weak, the branches are sparse and easy to be whorled, and the pruning of the growing season focuses on coring, leaving a length of 30ml / 40cm to promote crown and fruit growth. Winter pruning is usually carried out before freezing after falling leaves, mainly by cutting short, and cutting off frozen dead branches.

VII. Disease and pest control

Pest control is an easy link in the cultivation and management of fig trees, because there are fewer diseases and insect pests, and the main pest is mulberry longicorn beetles. Mulberry longicorn beetles, commonly known as buffalo, larvae eat branches, dry xylem, affecting the growth of trees. Adults appear in early June. Prevention and control measures can be killed manually or killed by drugs. Manual hunting can be carried out during the peak period of adults, and spraying 50% acephate 800 × 1000 times can kill adults quickly and effectively. Fig trees have strong adaptability and relatively easy cultivation and management. as long as you pay more attention, you can get something.
