Summer management technology of lemon

Lemon taste extremely sour, but in the market is very popular, it is rich in vitamins, but also has the effect of beauty, deeply loved by female friends. Summer is the period of young fruit expansion, summer shoot sprouting and physiological fruit drop, when the focus of management is to ensure lemon yield and improve quality, so how to manage lemon in summer? Let's take a look.

1. Soil, fertilizer and water management

High temperature and rainy summer, high humidity in the orchard, which is not conducive to the growth of lemon, so it is necessary to strengthen inter-garden drainage and manage the drainage ditch; in case of drought, when the soil moisture is less than 60%, you should immediately irrigate to ensure that there is not enough water in the young fruit stage of lemon. If there is not enough water, you can use water-saving irrigation methods, such as sprinkler irrigation or drip irrigation, and cover with straw or straw after irrigation to humidify and cool down. Summer young fruit expansion and summer shoot hair, both need a lot of nutrients, lack of nutrients may lead to poor growth, so it is necessary to apply strong fruit fertilizer in time. Fertilization should be determined according to the weather conditions, and the amount of fertilizer should be determined according to soil fertility and tree potential. Generally, young trees should be fertilized 5-10 times a year, mainly rapidly available nitrogen fertilizer, combined with phosphate fertilizer, potassium fertilizer and human and animal manure. As a result, the annual fertilization times of trees are 5-6 times, foliar fertilizer is applied several times in the tender shoot growth period, and strong fruit fertilizer should be re-applied in summer. In winter leisure season, we should combine shallow ploughing to cultivate soil, dig trenches in the canopy, apply 100kg compost or stable manure to each plant, mix it with the soil, and then cover the soil.

2. Summer pruning

Pruning in summer is very important, mainly for young trees. After the summer shoots are ripe, they are coring at the full buds at 40 cm from the ground, prompting 4-6 new shoots at 30-40 cm to form branches. For adult fruiting trees, summer shoots should be wiped out in time to avoid summer shoot growth and fruit competition for water and fertilizer, reduce secondary physiological fruit drop, and cut off weak branches, disease and insect branches, dense branches and overgrown branches to maintain good crown permeability. for some hanging fruit watering, weak trees can strengthen fertilizer and water management after moderate re-pruning in front of the Summer Solstice, promote their strong tree potential and lay the foundation for high yield in the coming year.

3. Fruit bagging

Fruit bagging is a common means to improve fruit yield and quality. Lemon bagging should choose lemon special paper bags with black inside and yellow double layers, and choose plant fruits with good tree potential, good management level or good appearance, free of disease and insect spots and 30-40 cm in diameter. The final sterilization and insecticidal output before bagging, so as to avoid poor bagging effect or loss of bagging effect.

4. Pest control

The main diseases and insect pests of lemons in summer are red spiders, rust wall lice, anthracnose, scab and so on. Red spiders can be sprayed with 2000 times of 20% Tetranychus EC; rust wall lice can be controlled with 2000 times of 10% benzoin mite suspension and new high fat film. Anthracnose and scab can be controlled with 3000 times of 10% high water dispersible granules.
