Juicing of citrus trees: from flower promotion to precision management of pups
As a widely grown economic fruit tree in the south of the country, citrus yields and quality have a direct impact on fruit-farm revenues. However, many growers suffer from faulty fertilization chains, resulting in low flowering, low yield rates and uneven quality of fruit. Taking into account the latest agricultural research and field experience, this paper provides a systematic overview of key nodes and technical points of fertilization of citrus trees throughout the year to help you achieve scientific management and productive growth。
I. Key period for promoting flowers: nutrition control during the guillotine split in september-december
Cultivation of citrus buds is a central element in determining the number of flowers to bloom in the coming year, usually from september to march. At this stage, emphasis will be placed on supplementing elements such as phosphorus, potassium, boron and zinc to inhibit nutritional growth and promote reproductive growth。
Soil fertilization strategy young-age tree: a strong tree but a weak budding capacity to control nitrogen fertilizer. It is recommended that the combination of 0. 2-0. 3 kg of high-phosphate potassium fertilizers, combined with 5-10 kg of decomposed organic fertilizers, be applied to each of the plants in september-october, to facilitate the absorption of roots and the separation of buds. Adult tree: post-harvest tree nutrients are high and need to be replenished in a timely manner. Between november and january of the following year, each application was 1 - 1. 5 kg of composite fertilizers applied, with 0. 5 kg of phosphate applied to enhance the resistance of the buds. Age tree: the root causes have been reduced in absorptive capacity, and organic fertilizer is required. After harvesting, 15-20 kg of fattening, 1-2 kg of biobacterium fattening, with 0. 5 kg of high nitrogen complex fatting, improved soil structure and activating root systems. Leaf spraying efficacy cobranium tint fertilizer: spraying 0. 1% bobron + 0. 2% potassium phosphate + 0. 1% zinc sulphate solution on the guillotine guillotine guillotine lumber + 2-3 times every 7-10 days can significantly improve the quality of the bud. Multi-activate argon regulation: for the long trees, 15% more than 150-200 times more than antenna is sprayed during the season of the autumn, inhibiting the hair of the winter acreage and reducing nutrient consumption. Ii. Precautionary fruit period: nutrition at flowering fruit season in march-may charge! Stab
Citrus bouquets and early fruit are the most competitive stages of nutrition, with the need to reduce physiological fallout and increase sitting rates through precision fertilization。
Nutrient nutrient supplementation: before spring rises (february-march) the application of organic water fattening with corrosive or algae to promote root system absorption; long-term (march-april) application of ammonium nitrate calcium calcium/stamp to supplement calcium and increase cell wall stability. Spraying of leaves: before flowering, application of 0. 2% boron + 0. 3% potassium phosphate to increase the energy of pollen; application of 20-50 ppm + cytone 100 ppm to promote larvae expansion at 2/3 sprouts. Control of nitrogen for stability: 15-20 days after flowering, the baby is standing firm, avoiding the application of nitrogen fattening, and preventing the production of a sprouts from competing with the fruit for nutrients. Spraying of 0. 3 per cent potassium dihydrophate + 0. 1 per cent ammonium molyte on the leaves enhances the resistance of fruit. Circumcised fruit: for the trees, the main dry or large branch is circumcised with a small knife during the pre-physio fallout period, the pelvis is cut off without harming the wood, the ration is cut off and the seating rate is increased. Iii. Cultivation period: june-october fruit expansion and quality improvement
This phase needs to balance nutritional growth with reproductive growth, promote even expansion of fruit and improve sugar accumulation and colour。
• june-july: 1 kg of composite weight per application of equilibrium + 0. 5 kg of potassium sulphate, combined with microelement fats (e. G. Zinc) to promote fruit cell fragmentation. August-september: adaptation of fertilization strategies to varieties: pre-maturized varieties (e. G. Golden autumn sugar oranges): control of nitrogen fertilizer, increased application of potassium dihydrogen phosphate and promotion of transcolored sugar. Medium- and late-literate varieties (e. G., umbilical, olympic): continued application of potassium nitrogen phosphorus to balance fertilizers with organic fertilisers to meet the demand for inflation. Water and soil management maintenance of soil moisture: in case of high-temperature droughts during the expansion period, water is required in a timely manner to avoid the lack of fissures in the fruit; attention is paid to drainage during the rainy season to prevent decay of the roots. Plank cover: cover the plate with straw or membrane to reduce water evaporation and stabilize soil temperature. Iv. Post-harvest recovery period: november-december tree restoration and sprouts reserve
The nutrient deficit in the post-harvest tree would require the restoration of tree positions through fertilization, laying the foundation for the splitting of buds in the coming year。
Fertilization time: fertilization immediately after early ripening, which can be applied 10 days before extraction. Fertilizer selection: organic fertilizer is dominated (e. G., decomposed farmers, commercial organic fertilizer), combined with balanced composite fertilizers, which account for between 40 and 50 per cent of the annual total. Fertilizer methods: use of cyclopedia or radial gavage at depths of 40-50 cm to promote deep roots. Cleaning and anti-frozen squirm spray: after fruit extraction application of thiomers or mineral oil to reduce the winter base of pests. Brush white: placing white trunks with lime water to prevent sun burning and freezing. Concluding remarks
The application of citrus fertilizers is based on the principles of “heavy-based fat, lean-tracked fattening and leaf fattening”, adjusted flexibly to the age of the tree, variety and climatic conditions. Scientific fertilization can significantly increase the rate of flower sit-ins and achieve a double harvest of fruit quality and yield. Farmers ' friends need to learn new technologies on a continuous basis, combining local practical optimization programmes, so that they can compete in markets and remain neutral。
