What are the key points of high-yield citrus planting management? Please accept this year-round planting strategy!

As a big citrus producing country, China is rich in citrus resources depending on good planting conditions, and growing citrus has become the basic choice of most growers. What are the key points of high-yield citrus planting management? Planting management is indispensable all the year round.

I. Spring of key points for high-yield citrus planting and management

Early spring is February is the dormant period before citrus trees sprout, until March, when the spring shoots sprout. During this period, the main focus of work is to promote bud and flower, and to apply spring fertilizer. Topdressing is mainly based on nitrogen fertilizer, supplemented by phosphorus fertilizer and potassium fertilizer. Fertilization should be combined with reasonable watering to ensure a smooth passage through the spring drought. At the same time, spring bud germination period, to pay attention to the prevention and treatment of scab, red spiders, can choose stone sulfur mixture, avermectin and other agents.

April gradually entered the flowering period of citrus trees, and also began the first physiological fruit drop period. In the meantime, it is necessary to do a good job in promoting fruit and preventing diseases and pests. A week or so after Xiehua, spray the flowers and fruits once to protect the flowers and fruits, and cut the big branches around to achieve the role of protecting the fruit. Scab, resin disease, anthrax, red spider, wood lice, whitefly, aphids and scale insects may occur during this period. Therefore, 40% difenoconazole 1500 times + imidacloprid 1500 times + azolidin 4000 times can be selected for control.

II. Summer of key points for high-yield citrus planting and management

May is the period of summer shoot emergence and the second physiological fruit drop of citrus trees, and the management of orchards is to protect fruit. During this period, in addition to cutting again, but also to control the summer shoot, timely drainage, do a good tree plate sunscreen cover. Diseases and insect pests that may occur during this period include anthracnose, scab, red spiders, aphids, leaf rollers, shell insects, and whitefly whitefly. During this period, we can use avermectin 2000 times solution for prevention and control.

June is the young fruit development period of citrus trees, which also needs to wipe the summer shoots and protect the fruit. During this period, high incidence of rust spiders and wood lice. Choose the spray of 15 mg of abamecyanide and 30 jin of water.

July is the fixed fruiting period, which continues to rub summer shoots until autumn shoots are released. During this period, it is necessary to prevent drought and keep moisture. At the same time, the diseases and insect pests during this period are rust wall lice, leaf miner, longicorn beetles and canker. Rust ticks and red spiders can choose avermecyanide or avermectin.

III. Autumn and winter key points of high-yield citrus planting management

August and September are the fruit expansion periods of citrus trees, and autumn shoots need to be released. In addition to preventing drought and moisturizing, it is also necessary to control diseases and insect pests during this period, such as fruit cracking, rust tick, leaf miner, resin disease, anthrax, soot, canker and brown rot. For cracking fruit, you can choose expansion anti-cracking factor; for canker, you can choose 0.5% Bordeaux solution or 77% copper calcium sulfate 500 times.

In October, the fruit of citrus trees matured and entered the harvest period. at this stage, strong shoots and strong fruits were needed to prepare for harvest. After the fruit is harvested in November, it is necessary to apply fertilizer in time, combined with deep ploughing of the soil, fertilization should be deep. It should be noted that it is not suitable to irrigate 10 days before harvest. Citrus fruits often suffer from insect damage, brown rot and green mold infection before harvest.

The dormancy period of citrus trees is from December to January, especially in January, attention should be paid to preventing frost injury and promoting flower bud differentiation. Therefore, pruning the tree, cultivating the tree potential and doing a good job of clearing the garden are the focus of winter management. During this period, frost damage may occur, so it is necessary to choose stone sulfur mixture + quicklime to whiten the trunk for heat preservation.

First of all, the high yield of citrus orchards is inseparable from the careful management all the year round, and it is not impossible to prescribe the right remedy to the constant demand of citrus trees in each season.
