Xiaobian sorted out the fertilization period and method of apple trees(wholesale greenhouse pots). The following is a detailed list for the reference of fruit friends. Therefore, the apple tree is applied before or after the flowering (in early April), after the flowering of the apple tree (in mid-May), the apple tree is generally best in the autumn (in the middle of September) ), flowering and timely preventing the loss of nutrients due to flowering(gallon pot), resulting in de-fertilization, increasing the rate of fruit set and promoting the growth of new shoots.
Generally, apples, pears, walnuts, chestnuts, grapes, etc(seed starter trays). Apple tree flower bud differentiation and young fruit expansion fertilizer (from the end of May to the beginning of June), this top dressing is to meet the needs of apple fruit enlargement, branch growth and flower bud differentiation, up to 70-80 cm, apple tree topdressing Potassium fertilizer is the main. In order to give full play to the fertilizer effect(bulk 15 gallon pots), the phosphate fertilizer should first be piled up with organic fertilizer and then mixed and applied.
(cheap greenhouse plastic starter pots wholesale)Also consider the combination of foliar spray + melon and fruit(flat plastic tray). Before July, spray 0.3%~0.5% urea solution + melon fruit and sedative. After July, spray 0.3%~0.5% potassium dihydrogen phosphate or fruit tree micro-fertilizer + melon fruit. The roots of the fruit trees are the main organs of the fruit trees. The absorption of fertilizer by the fruit trees is mainly done by the root hairs in the roots(bulk 20 gallon pots). Fertilization in the concentrated distribution of roots is one of the keys to improve fertilizer efficiency.
Apple trees are generally fertilized(square nursery pots), but most of them are concentrated on the outer edge of the canopy projection or a little further away. Its vertical distribution varies with tree species, soil quality, and management level. have a deep distribution of roots, but more than 80% of the roots are concentrated in soil layers of about 60 cm. The roots of peach, apricot, plum, and cherry are lightly distributed(injection molded nursery pots), and most of them are generally In a soil layer of about 40 cm.
(cheap greenhouse plastic starter pots wholesale)If the tree is weak, the branches and leaves are slowly elongated, and the leaves are yellow or yellowish(plastic grow pots), this indicates that the trees are hypoxic and iron-deficient, and the nitrogen fertilizer should be sprayed mainly, and some ferric citrate and phosphate fertilizers and potassium fertilizers should be sprayed properly; The base fertilizer of apple trees is mainly based on farmyard manure(blow molded nursery pots), and the phosphate fertilizer is applied in full according to the total amount of the whole year.
When fertilizing, the fertilizer should be applied according to this feature(cell trays). On the contrary, shallow application, organic fertilizer decomposition is slower, the fertilizer supply period is longer, it is better to apply fertilizer, and the fertilizer has greater mobility and can be applied shallowly. For example, organic fertilizer, apple and other deep fruit trees are applied at a depth of 40-60 cm(1 gallon nursery pots wholesale), while peaches and other shallow-rooted fruit trees are 30-40 cm.(cheap greenhouse plastic starter pots wholesale)
At the same time(greenhouse supplies pots), fertilization should be based on the crown projection edge and a little farther, so that the fertilizer effect can be maximized.if the leaves are green and green, If the branches are too long and the nitrogen fertilizer is sufficient, the application of phosphate fertilizer and potassium fertilizer should be applied, and some trace elements should be sprayed appropriately(2 gallon nursery pots wholesale). It is carried out after 5 pm on the cloudy or sunny days of fruit trees in the early flowering, flowering and strong fruiting periods.
