Cotton prevention of frost damage, falling buds and bolls, premature aging micro-fertilizer solution 1. Common problems during seedling stage-budding stage: poor root system, slow growth, low temperature freezing injury, many diseases, low survival rate

Potato, Huaishan and other rhizome and tuber crops to increase yield and disease resistance

Grape high-yield and high-quality water and fertilizer integration plan

Citrus prevention plan for yellow trees and yellow leaves: the first stage: spring shoots-flowering common problems: solution: flushing: 1.5 kg, water 10,000 kg, 200 trees, conditioning soil acidity; 2. calcium 15 kg, Watering more than 10,000 kg, pouring 200 trees, promoting roots and strong roots, reducing spring shoots, small leaves, green leaves, not turning green; spraying: 2 two per tree, spraying with large fertilizer or buried spray: boron 1500 times, flower buds exposed white-spray 1-2 times before blooming, strong flower buds, prevent and reduce weak flowers, deformed flowers, and improve fruit retention rate in the later stage;

Banana to prevent deficient yellow leaves, disease-resistant and high-yield water and fertilizer integration program: Phase 1: Common problems in seedling stage: Solution: Washing: 1-3 kg of calcium +1 kg / mu, 1000 kg or more in water, small seedling stage, Drain 1 time; Drain 2 times in the large seedling stage, promote the development of root system, more white roots, strong fertilizer absorption ability, raise seedlings and strong seedlings. Spread or bury with big fertilizer, need to be more than 10 cm from the base of the stem; spraying: add each spray, lack of yellow leaves, and banana leaves are large and green;

Sugarcane root-promoting seedlings, provincial fertilizer to increase micro-fertilizer solution: 1. Common problems in seedling stage: Solution: Spread / burial: 5 kg / mu, before planting, bury or spread with bottom fertilizer once, calcium and magnesium Zinc and boron supplements improve the efficiency of big fertilizers and promote roots and seedlings. Spraying: 1 kg of calcium, dripping twice after emergence, interval of 7-10 days, supplementing phosphorus and calcium, promoting new roots, raising seedlings and reducing dead seedlings; spraying: sugarcane seedling stage, low temperature stage, rapid growth period Spray and add each time to protect the leaves and strong seedlings.

蜜柚预防黄叶、败树、大小年营养方案：1、春梢-花期，常见问题：树势差，春梢不转绿，花弱、畸形花多，后期难保果。 　　解决方案：冲施：钙15公斤+镁5公斤，兑1万斤水以上，淋150棵树以上，促根壮树，预防黄叶黄树;(无法淋水肥的果园，可用3两/树，随大肥撒施或埋施) 喷施：春梢-开花前，各喷1-2次，促花壮花保叶;

After harvesting, yellow bark fertilizes to help restore the growth of the fruit trees. At the same time, it shoots up to provide a robust fruit-bearing female branch for the coming year. Two tasks must be done. First, yellow bark harvest resumes growth. Attention should also be paid to calcium, magnesium, zinc and boron supplementation. Calcium supplementation promotes the growth of roots and promotes the development of new shoots. Secondly, zinc and boron supplementation is used to accumulate nutrients for flower bud differentiation in the tree in advance. When a batch of shoots begin to mature, the foliage is sprayed with micro-fertilizer to promote flower bud differentiation.

The serious acidification of the soil directly affects the growth of the root system and the ability of the roots to absorb nutrients. In addition, the acidity of the soil environment is more likely to breed soil-borne diseases and affect the overall growth of blueberries. Regularly adjusting soil acidity to improve the growth environment of the root system will also help improve the absorption and utilization of fertilizers. Drip irrigation or flush application can be used alone to neutralize acid soil and condition soil pH.
