Plastic Greenhouse Pots Wholesale Price Poland


According to the ratio of nitrogen, phosphorus and potassium fertilizer, apple saplings are 1:2:1, fruiting trees are 2:1:2, pears are 1:1:1, loam is 1:2:1, and sandy soil is 1:1:1(4 cell propagation trays wholesale). However, the amount of fertilization must be appropriate to facilitate the growth and development of fruit trees(104 cell propagation trays wholesale). This method is easy to operate and economical to use fertilizer. The fertilizer circle should be expanded year by year.

For example, the root system of apple, pear, etc. should be deep and wide, and the fertilization should be deep and wide(plant start trays wholesale). The root system of plum and cherry should be distributed shallowly, the fertilization should be shallow and the range should be small(6 cell propagation trays wholesale). The amount of N 1 per tree in full fruit stage~ One point five Kilogram, phosphorus Zero point five Kilogram, potassium 1~ one point two five kg, and does not cause soil hardening.


(plastic greenhouse pots wholesale price poland)With the increase of tree age, the range and depth of fertilization and the amount of fertilization should also be expanded year by year(cheap plastic plant pots bulk). Sandy land and sloping land should be applied in the critical period when fruit trees need fertilizer. The base fertilizer should be applied in depth(8 cell propagation trays wholesale). Nitrogen fertilizer has a strong mobility in the soil, and even shallow application can penetrate into the root concentrated distribution layer.


The mobility of K fertilizer is poor, and that of P fertilizer is worse(propagation tray). The common methods of fertilization in production are as follows: Ring fertilization is to dig a ring-shaped ditch a little far away from the crown to apply fertilizer. The ditch is 30-40cn wide and 30-45cm deep, in a ring or semi ring shape(12 cell propagation trays wholesale). The fertilizer and soil are fully mixed, applied into the ditch, and then covered with soil. This method is suitable for big trees at full fruit stage.


This method is applicable to young trees(seed starting trays). The depth and breadth of fertilization are related to tree species, varieties, tree age, rootstock, soil and fertilizer types. This method is often used in the whole orchard to fertilize adult fruit trees or close planting orchards(18 cell propagation trays wholesale). Generally, P and K fertilizer should be applied deeply, especially P fertilizer should be applied in the root distribution layer, which is beneficial to root absorption.(plastic greenhouse pots wholesale price poland)


Therefore, the organic fertilizer is generally applied to the root system(square grow pots), which is a little deep and far away from the root system, to induce the root system to grow deeper and wider, form a strong root system, expand the absorption area, improve the root absorption efficiency and the tree nutrition level, and enhance the stress resistance of fruit trees(36 cell propagation trays wholesale). Spread the fertilizer evenly in the garden, and then turn it into the soil.


The radial ditch fertilization is centered on the tree trunk, which is 1m away from the tree trunk(large plastic terracotta pots). Four to eight radial ditches are dug from the inside to the outside, from the shallow to the deep. The width of the inner end of the ditch is 30cm, and the width of the outer end is 50 to 60cm(40 cell propagation trays wholesale). This method is economical in water use, wide and uniform in soaking range. It is suitable for areas where water sources are scarce.


(plastic greenhouse pots wholesale price poland)After the fertilizer and soil are mixed, they are applied and covered with soil(flat plastic tray). This method is less harmful than ring fertilization, but it also needs to avoid the big roots when digging the ditch, and change the position of radiation ditch every other year or every other time(50 cell seedling trays wholesale). The horizontal roots of fruit trees are generally distributed in a little distance around the crown, and the roots have the characteristics of fertilizer.


Generally, this method is more reliable(plastic plant pots wholesale suppliers). The multi-point experiment of national Apple fertilizer test network shows that the furrow fertilization can be applied between rows, between plants or across rows of fruit trees, and the horizontal or vertical long furrows can be dug(51 cell propagation trays wholesale). The slope can only be dug horizontally along the contour line, or combined with deep turning, which is more convenient for mechanization.
