When do peaches ripen? A list of the main pests and diseases of greenhouse peach trees
Young peach trees grow fast and form flower buds easily. Plant a tree in the same year, adopt greenhouse cultivation in the same winter, and it will immediately bloom and bear fruit; by the spring of the second year you can already gain economic returns. So more and more growers are starting to plant peaches. So when do peaches ripen as a fruit? What are the main pests and diseases in greenhouse cultivation? What are the points to note when planting?
1. When do peaches ripen as a fruit?
Peaches bloom in March-April. After the flowering period ends, they grow into peaches, and it takes 3-6 months for them to ripen. Different types of peaches ripen at different times. Peaches start to appear in summer, and all the way into autumn, peaches are an in-season fruit. Most peaches ripen from June to September, and a small number ripen earlier or later.
2. What are the main pests and diseases in greenhouse cultivation?
The main pests and diseases of greenhouse peach trees include aphids, gray mold, and bacterial shot hole disease.
1. Aphids: Before bud break, spray lime sulfur mixture at 3-5 degrees Baume. 10-15 days after petal fall, use 2.5% pirimicarb wettable powder at 1500 times dilution to control aphids.
2. Gray mold: When gray mold occurs in the greenhouse, use 80% vinclozolin wettable powder at 800 times dilution for control. You can also use 10% gray mold fumigant smoke agent at 250-450 grams per mu to fumigate the greenhouse, or use dust agents such as 5% meimeiling, 6.5% jiaimeiling, 5% chlorothalonil, etc., at 1 kilogram per mu.
3. Bacterial shot hole disease: Streptomycin sulfate at 200 mg/L can be used. After the film is removed, pest and disease control follows that of open-field cultivation. Harvest at the right time. For protected cultivation, the fruit's value lies in being early; the earlier it hits the market, the better the price. Therefore, harvest the fruit promptly when it ripens, but harvest at the right time. Harvesting too early gives poor fruit flavor, and harvesting too late makes the fruit unsuitable for transport. Generally, eight or nine parts ripe is ideal. Fruit on different parts of the tree ripens unevenly, so harvest in batches. After harvesting, pack in small boxes and sell promptly.
3. Points to note when growing peaches in greenhouses
1. Choose varieties suitable for greenhouse cultivation, such as Chunlei and Wuyuehuo.
2. According to the planned market time, choose the type of plastic greenhouse and the appropriate time to cover it.
3. Reasonably control the temperature and humidity inside the greenhouse. In the early stage, ensure the chilling requirement is met; afterward, ensure the temperature and humidity needed for flowering, fruiting, leaf growth, and fruit growth.
4. Carry out artificial pollination to increase the fruit set rate, using measures such as brushing pollen with a feather duster and hand pollination, to ensure enough fruit forms, thereby ensuring yield and improving returns.
5. Strengthen fertilizer and water management to ensure the peach tree's fertilizer and water needs at every growth stage.
6. Carry out year-round pruning; control tree height to meet the requirements of greenhouse cultivation while also having enough nutritional area to ensure a balance between fruiting and tree growth.
