If 5 kilograms of potassium chloride is applied per mu(200 cell seed trays wholesale), there is a reasonable absorption ratio of nitrogen, phosphorus, and potassium that has been scientifically determined. Set an application amount of various inorganic fertilizers. This fertilizer is often in the form of granular fertilizer(4 inch plastic pots bulk). Although the total nutrient content of granular fertilizer is many, most of them are changed from quick-acting to slow-acting.

For fruit trees, the potassium absorption intensity from tillering to booting stage is the strongest and potassium has the characteristics of being transferred and reusable in the body(200 cell seedling trays wholesale). For fertilization of fruit trees, we should refer to this fertilizer amount and the characteristics of nutrient requirements of fruit trees at different periods of the year, and focus on applying fertilizers of different ingredients in stages(98 cell plug trays).
To control the amount of fertilizer, the fertilizer damage will be greatly reduced(32 cell seedling trays wholesale). Generally, the application of ammonium bicarbonate per mu should not exceed 30 kg, and urea should not exceed 10 kg. It is not advisable to spread on the surface of the soil, and every 100 kilograms of fruit produced, and distribute the fertilizer evenly throughout the cultivation layer(polystyrene plug plant trays). The hole application should be more than 10 cm away from the crop roots.
At present, there are many compound or mixed granular fertilizers, some of which contain about 15% of nitrogen, phosphorus and potassium nutrients, and some are 10%, etc.(2.5 inch square plastic pots), which is the so-called nitrogen, phosphorus and potassium ternary compound fertilizer. This avoids the sudden high concentration of soil solution that can burn the root system(shallow germination trays). Peach fruit cracking should be supplemented with calcium fertilizer.
For example, in autumn, the particles need to be softened in the soil, and the nutrients in them are gradually released(1 gallon nursery pots bulk). This is mainly due to the lack of vitamins. The main reason is calcium deficiency. Peach trees are particularly sensitive to calcium(5 gallon plastic nursery pots). Not only does the calcium deficiency appear soft and rot in the abdominal line, but the hardness of the entire peach is also reduced. The taste deteriorates and the storage capacity decreases.
Organic fertilizer is not fermented(2 gallon nursery pots bulk). After being applied to the soil, a lot of heat is generated during the fermentation process, which burns the tender absorption roots, which greatly affects the absorption capacity of the roots, makes the tree weak and premature aging, and even death. absorb(black plastic plant pots wholesale). The effect of foliar calcium supplementation is generally not too obvious. Refers to the annual fertilization of fruit trees.
There are two ways to absorb calcium, one is root absorption, and the other is foliar absorption(3 gallon nursery pots bulk). In recent years, many fruit farmers have used a lot of unripe organic fertilizers, especially chicken manure. It is recommended to choose mannitol chelated calcium, Hehuang chelated calcium(bulk buy plastic plant pots), according to the need of potassium in young rice tissues, foliar fertilizer can be sprayed 2 to 3 times, or fruit and vegetable calcium, etc.
These calcium fertilizers can be transmitted up and down, left and right in the tree body, so that the calcium on the leaf surface can be transmitted to the fruit, increasing calcium Use effect(5 gallon nursery pots bulk). Trees are weak, and those with more fruits should be topdressed with quick-acting fertilizers(4 inch plastic pots wholesale). Compound fertilizer 0.2-0.3 kg per plant, potassium fertilizer 0.15-0.2 kg, compound fertilizer 0.5-1.0 per tree Kg, urea 0.3 ~ 0.5 kg.
