  • Land inspections find the problem of inflated cultivated land retention figures remains prominent

    The No. 1 National Land Inspection Announcement of 2015 released on the 28th shows that in some places, illegal and irregular land use, especially the indiscriminate occupation and abuse of cultivated land, false balance of cultivated land occupation and compensation, and inflated cultivated land retention figures remain prominent. According to the announcement, in 2014, targeting the fulfillment of the target responsibility for cultivated land protection

  • A Detailed Guide to May Citrus Fruit Retention Methods and Precautions

    From early to mid-May through the end of May is the critical period for stabilizing citrus fruit set. In citrus production, this period is commonly called the fruit retention period - fruit stabilization period. This is the key period that determines yield. So what are the May citrus fruit retention methods? What aspects need attention? 1. May citrus

  • What Pesticides to Use for Flower and Fruit Retention in Lychee? A Detailed Explanation of the Best Pesticide Formula

    Abstract: During the young fruit pit-filling stage 10-15 days after the female flowers bloom, combined with pest and disease control, add 0.3kg of urea and 0.2kg of monopotassium phosphate to every 100kg of water, mix well, and spray on the young fruits. During the embryo abortion stage from May 20-25, add 0.4kg of urea and 25-30ml of Baoguoling to every 100kg of water, mix well, and spray on the fruits.

  • What are the summer management measures for walnut trees?

    Summary Flower and fruit retention: thin out the vigorously growing female flowers, then carry out supplementary artificial pollination. Fertilization: during the vigorous growth period of female flowers, spray gibberellin, boron fertilizer and urea once every 15 days. Branch bending: pull the upturned branches into position. Pest and disease control: for rot disease, apply

  • What are the measures for citrus flower and fruit retention

    Abstract Fertilization and spraying: Citrus can be sprayed with trace elements and flower-promoting and fruit-retaining agents before flowering. Water management: During the fruit-retention period, the soil should be kept moist, and drainage should be done well during the rainy season. Girdling for fruit retention: In the early stage of physiological fruit drop, a small knife can be used to girdle the trunk or a large branch 1 ring; it is necessary to cut through the phloem, but the xylem must not be damaged.

  • Detailed Explanation of Key Techniques for Flower and Fruit Retention in Navel Oranges

    The ultimate purpose of growing navel oranges is to obtain a good return, and the yield of navel oranges is, apart from the price factor, the hard guarantee for obtaining benefits. To achieve high yield, besides reasonable cultivation and planting and a suitable growing environment and climate, the number of flowers and fruits

  • Key Technical Points for Flower and Fruit Retention and Post-Bloom Management of Persimmon Trees

    Persimmon is a berry-type fruit of the Ebenaceae family (persimmon family). Its ripening season is around October. The fruits come in many shapes, such as spherical, oblate, nearly conical, and square.

Navel oranges are rich in nutrients and contain various nutritional components essential to the human body. Navel oranges contain large amounts of vitamin C and carotene, which can inhibit the formation of carcinogens,

  • Key Technical Points for Flower and Fruit Retention in Citrus Cultivation

    The 2-3 months from bud emergence to fruit set stabilization is the most important period of the year for citrus trees. For a good harvest, comprehensive flower and fruit retention measures must be taken according to the growth conditions of the citrus trees and changes in weather. 1. Reasonable fertilization: For citrus orchards that were not fertilized last winter, organic fertilizer should be supplemented as soon as possible. For adult trees, apply 5-10 kg of chicken manure or 1-2 loads of farmyard manure per tree, plus an appropriate amount of urea, and bury it around the root zone. The fertilization principle during the flower and fruit retention period is: nitrogen-based in the early stage, emphasis on potassium with phosphorus supplementation in the later stage; combining soil fertilization with foliar feeding. For the post-bloom fertilizer, apply compound fertilizer plus an appropriate amount of urea during the flower-falling period to promptly replenish nutrients consumed during flowering; for the fruit-setting fertilizer, apply potassium fertilizer plus an appropriate amount of phosphorus fertilizer; for the fruit-swelling fertilizer, apply compound fertilizer plus potassium fertilizer. For foliar feeding, spray 0.2% monopotassium phosphate twice from spring bud break to before flowering, spray nucleotides during rainy days, and add 0.1% borax to one of the applications; during the young fruit stage, spray foliar fertilizer 2-3 times in combination with pest and disease control or fruit retention, with the first foliar spray including 0.1% magnesium sulfate and 0.1% zinc sulfate.</p><p>2. Soil management: Repair drainage ditches inside and outside the orchard to remove standing water, so that waterlogging on rainy days does not affect root growth or even cause root rot leading to flower and fruit drop. During continuous dry and hot weather lasting more than 10 days, irrigate promptly to keep the soil moist and loose, which helps the root system absorb water and nutrients.</p><p>3. Scientific use of growth regulators: Plant growth regulators commonly used for citrus fruit retention include 2,4-D, fruit-retention hormone, triacontanol, 920, and fruit-retention agents. Use them 2-3 times after flower drop, spraying once every about 15 days. Alternating different growth regulators gives better results. For seedless and few-seeded citrus varieties, using 920 or triacontanol for fruit retention gives better results.</p><p>4. Pest and disease control: During the flowering and fruiting period, the main pests and diseases include red spider mites, rust mites, aphids, citrus blossom midges, tortrix moths, anthracnose, and scab. For aphid control during the spring shoot stage, use omethoate or monocrotophos; in early to mid-April (or early March if drought occurs), control red spider mites, and in mid-to-late April control rust mites, using acaricides or biological pesticides for spraying; spray organophosphorus pesticides at the early bud stage to kill citrus blossom midges and tortrix moths; for diseases, focus on prevention, using fungicides such as copper oxychloride or thiophanate-methyl.</p><p>5. Control early summer shoots: From May to mid-June, promptly remove early summer shoots to avoid competition between shoots and fruit for nutrients, which benefits young fruit development and reduces fruit drop. For vigorous trees with few flowers and few fruits, girdle the trunk 25 days after flower drop to retain fruit, which can also control summer shoots.</p>
