Second, planting techniques of lemon trees in the four seasons

1. Selecting and planting gardens

Lemons like the subtropical climate that is warm in winter and cool in summer. The average annual temperature is more than 18 ℃, the annual active accumulated temperature of ≥ 10 ℃ is about 5: 500 ℃, the extremely low temperature is more than-2.5 ℃, the annual rainfall is more than 1000mm, and the annual sunshine hours are more than 1000 hours. It has wide cultivation adaptability, flat land, mountainous land and hilly land, and there is no special soil and terrain planting requirements. However, the water source is sufficient, the transportation is convenient, the soil layer is deep, the soil is loose, the moisture and fertility is strong, the slightly acidic soil is the best. It can be planted all the year round, mainly in spring and autumn, with an average of 60 plants in 667m2.

2. Fertilizer and water management

The lemon of the four seasons should shoot, blossom and bear fruit many times a year, which requires adequate supply of fertilizer and water. The principle of organic fertilizer and compound fertilizer should be adopted in fertilization technology. After harvest, organic fertilizer is suitable to be applied as base fertilizer, compound fertilizer is applied step by step, and thin fertilizer is used as topdressing. The unfruited trees were mainly applied nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, and mainly applied to promote shoot fertilizer. Second, promote the formation of the crown and exuberant growth of the tree. Results the tree is generally fertilized 3-4 times a year, and the amount of fertilizer is determined according to the amount of fruit and soil fertility, mainly farm manure, and topdressing urea and phosphorus and potassium fertilizer combined with growth. Early application of spring fertilizer, heavy application of strong fruit fertilizer and supplementary application of fruit picking fertilizer. Lemon is very sensitive to water, water management should be appropriate, drainage should be paid attention to in the rainy season, and timely irrigation in the dry season. There are few root groups of young lemon trees in the four seasons, so it is necessary to irrigate a small amount of water for many times. The adult trees have sufficient water supply in spring shoot initiation stage, young fruit stage and fruit expansion stage. The supply of fertilizer and water throughout the year is less in spring and autumn and larger in the middle of summer.

3. Reasonable pruning

The growth of young lemon trees in the four seasons is exuberant, so they should be light rather than heavy when pruning, focusing on cultivating round-headed crowns to create high-yielding trees. With the increase of tree age, the yield and the amount of pruning should be increased year by year, so as to improve the ventilation and light transmission condition of the crown and maintain the high-yield tree shape. Lemon pruning can be carried out all year round. The first fruit trees should be trimmed lightly, mainly in winter and spring, supplemented by coring and cutting in summer, light and long. Fruit trees are mainly pruned in summer, wiping buds, picking hearts, combined with short thinning. The weak trees are heavily cut in winter and lightly cut in summer to rejuvenate the branches so that they continue to bear fruit.

4. Protect flowers and fruits

Lemon in the four seasons has the characteristics of exuberant growth, with continuous flowers and fruits throughout the year, a large number of flowers, and heavy falling flowers and fruits. Among the many flowers and fruits, the quality of spring flowers and fruits is the best. Before setting fruit in the first crop, we should strengthen the management of flowers to ensure that the number of flowers is sufficient and increase the amount of fruit. When there are too many spring flowers and fruits, fruit thinning can be carried out after physiological fruit drop, and summer flowers and fruits can be used to supplement the shortage of spring flowers and fruits to ensure reasonable annual results, high yield, stable yield and high quality.

5. Fruit bagging

The special bag of lemon fruit can be selected after stabilizing the fruit to reduce the harm of diseases and insect pests, reduce pesticide residues and improve fruit quality. Before bagging, the crown should be sprayed with insecticides and fungicides with high efficiency, low toxicity and low residue, and the mouth of the bagging bag should be tightly fastened. Usually, after bagging, the first-class fruit rate can reach more than 70%, the appearance of the fruit is beautiful, and the price is high.

6. Harvest and storage

The four seasons lemon blossoms continuously in a year, and it can be picked by stages many times, using the method of "one fruit and two cuts" to pick fruit. The color of the fruit changes from dark green to light green, and the fruit can be harvested with light. The fruits should be picked and placed lightly, and the picked fruits should be graded to avoid exposure to the sun. Perfume lemon is more resistant to storage, generally under natural conditions, there are no diseases and insect pests, and healthy fruits without damage can be stored for 1-2 months.

There is a great market demand for lemons in the four seasons, and the economic benefits are considerable, but farmers had better make an inspection before deciding to plant them so as not to lose money.
