Sichuan belongs to subtropical humid climate, which is very suitable for some fruits. So what fruits are suitable for Sichuan? The following are the kinds of fruits that I have carefully arranged for you and are suitable for growing in Sichuan. Let's have a look.

Fruit varieties suitable for planting in Sichuan

Citrus.

The growth, flowering and fruiting of citrus fruit trees are closely related to environmental conditions such as temperature, sunshine, moisture (humidity), soil, wind, altitude, topography and slope direction, among which temperature has the greatest influence. Even if the temperature difference is 0.5℃, sometimes there will be completely different results. The growth and development of citrus need a temperature of 65438 02.5 ~ 37℃. The day and night temperatures of flower bud differentiation in autumn are about 20℃ and 65438 00℃, respectively, and the soil temperature of root growth is roughly the same as the ground temperature. If the temperature is too low, oranges will be frozen. When the sweet orange is at -4℃ and the satsuma orange is at -5℃, the branches and leaves will be frozen. When the sweet orange is below -5℃ and the satsuma orange is below -6℃, the plants will freeze to death.

temperature

High temperature is also not conducive to the growth and development of citrus. When the air temperature and soil temperature are higher than 37℃, fruits and roots stop growing. Temperature also has obvious influence on fruit quality: in a certain temperature range, with the increase of temperature, the sugar content and soluble solids increase, the acid content decreases and the quality becomes better. Citrus is a tree species with strong shade tolerance, but good sunshine is needed for high quality and high yield. Generally, areas with annual sunshine hours 1200 ~ 2200 hours can grow normally. For example, compared with Chongqing citrus producing areas with less sunshine, South China with good sunshine and abundant calories has higher sugar content, lower acid content and higher sugar and acid content. Generally, tropical and subtropical regions with annual rainfall of about 1000mm are suitable for citrus planting, but irrigation is often needed because of uneven distribution of annual rainfall. The suitable relative water content of soil is 60% ~ 80%, and irrigation is needed when it is lower than 60%. Too much rain will cause soil water accumulation or high groundwater level and poor drainage in citrus orchards, resulting in root death. Citrus fruit trees require that the air relative humidity should be around 75%.

land

Citrus can adapt to a wide range of soils. Purple soil, red and yellow soil, beaches and beaches can all grow at pH 4.5 ~ 8, and pH 5.5 ~ 6.5 is the most suitable. The growth of citrus roots needs high oxygen content, and the soil with loose texture, good structure, organic matter content of 2% ~ 3% and good drainage is the most suitable.

Fruits suitable for southern cultivation

grape

Grape is a woody vine of Vitaceae, which originated in West Asia and is now cultivated all over the world. About 95% of the grapes in the world are concentrated in the northern hemisphere. The main grape producing areas in China are Turpan and Hotan in Xinjiang, Yantai in Shandong, Zhangjiakou, Xuanhua and Changli in Hebei, Quan Min and Yifeng in Dalian, Xiong Yue, Shenyang and Henan.

banana

Bananas like hot and humid climate, and grow vigorously on the land with deep soil layer, loose soil and good drainage. Irrigation planting is also successful in semi-arid areas such as southern Jamaica. Wild bananas are cultivated by seeds, and artificial bananas can be cultivated by root sucking and pseudobulb ramets. The first harvest takes 10 ~ 15 months, and then the harvest is almost continuous.

loquat

Loquat, also known as Lu Ju, Jin Wan, Lu Zhi, etc. , like light, slightly shade-tolerant, like warm climate, moist soil with rich water and good drainage, slightly cold-resistant, not cold-resistant, slow growth, average temperature above 65,438+02 ~ 65,438+05, winter not lower than -5℃, flowering and young fruit not lower than 0℃.

Chinese olive

Olive belongs to the genus Olive, belonging to the family Olive. It likes warmth, and it needs proper high temperature to grow vigorously during the growing period, with good effect. The annual average temperature is above 20℃, which is most suitable for growing in areas without severe frost and freezing injury in winter. In winter, it can tolerate a short-term low temperature of MINUS 3℃, but when the temperature drops below 4℃, serious freezing damage will occur. Areas with rainfall of 1200 ~ 1400 mm can grow normally and have wide adaptability to soil. They can be cultivated along rivers, hills, mountains, red yellow soil and gravel soil, and can grow well as long as the soil layer is deep and the drainage is good.

peach

Peach is a small deciduous tree of Prunus in Rosaceae, which is planted all over the world. Flowers are ornamental, fruits are juicy, and can be eaten raw, pickled or canned, and nucleolus can also be eaten. The flesh is white and yellow, and there are many varieties of peaches. Generally, the skin is hairy. Nectarine skin is smooth. Flat peach? The fruit is flat and disc-shaped. Peach? This is an ornamental peach tree with various forms of petals.

pear

Pear is a perennial deciduous tree fruit tree of Rosaceae, which is distributed in North China, Northeast China, Northwest China and the Yangtze River valley provinces. There are many kinds and varieties, and the adaptability to the external environment is stronger than that of apples. Cold tolerance, drought tolerance, waterlogging tolerance and salt tolerance. In areas where the lowest temperature in winter is above -25 degrees, most varieties can survive the winter safely.

Citrus planting method in Sichuan

1. Planting improved varieties and disease-free seedlings

Selecting excellent varieties and planting strong seedlings are the basis of efficient cultivation of citrus. Therefore, we must attach great importance to the propagation and management of seedlings. High starting point, high technology, high quality and high standard? Guide and standardize seedling propagation, adopt advanced virus-free seedling propagation technology, cultivate excellent varieties and strong seedlings of virus-free seedlings, and lay a good foundation for efficient cultivation of citrus.

2. Build a garden and plant it

Garden construction is to provide suitable growth conditions such as light, heat, water, gas and fertilizer for citrus production, and provide good environmental conditions and traffic conditions for high yield and high quality of citrus, thus reducing production costs and improving production efficiency. Construction of necessary roads, community division, irrigation and drainage, water storage, windbreaks, fertilizer sources and ancillary facilities. Fast-growing tree species are selected for windbreaks, and there are no natural pests and diseases with citrus.

plant

The planting density of citrus varies with different countries, different periods, different citrus varieties and how to control citrus yellowing trees. In China and Japan, the planting density is relatively high. Compared with the 1970s and 1980s, the planting density is getting smaller and smaller, which tends to be reasonable. Planting methods include rectangle, square, triangle, wide and narrow rows and contour planting. As far as planting methods are concerned, citrus can be planted all year round, but mainly in autumn, spring and Xia San.

4. Soil, water and fertilizer management

Soil management is the basis of the growth and development of citrus fruit trees. Creating soil conditions such as fertilizer, water, gas and heat suitable for tree growth is the goal of soil management, and to achieve this goal, measures such as deep tillage and application of organic fertilizer, green manure, intercropping, soil covering and fertilization, intertillage and soil and water conservation should be taken to keep the soil in good fertility and the best structural state.

5. Plastic pruning management

Pruning of citrus is to make plants form and maintain a reasonable tree structure, make full use of light energy and space, and achieve the purpose of early fruiting, early and high yield, stable yield, high quality and high efficiency, and directly prune trees or other similar operations. In the final analysis, shaping is to trim the tree shape and form an ideal tree structure; Pruning is a direct branch treatment technology for trees, such as thinning, short cutting, retraction, coring, bud removal, bending branches, ring cutting, root cutting and so on.
