Before the seedling stage and heading stage of crops, 250 L water solution of 0.01% - 0.1% concentration is used every 667 square meters to irrigate near the roots of crops(plastic plant trays wholesale). The application of long melon fertilizer can promote the early and large melon, but it should be applied according to the soil strength and seedling situation(128 cell seed starter trays). If this standard is not met, the product quality is not up to the requirements.

According to the analysis of wheat plants(gallon pot), 412kg of winter wheat is produced per mu, and the nitrogen absorbed from emergence, tillering to rising and jointing after winter accounts for 40% of the total amount of the whole growth period, and the phosphorus and potassium account for 20% of the total amount respectively(seed plug trays wholesale); the total phosphorus accounts for 67% and the total potassium accounts for 65%.
(cheap large plastic plant pots wholesale price australia)Watermelon has a long vine and a large leaf area(greenhouse supplies pots). At full fruit stage, about 1.5kg compound fertilizer is generally applied to trees. Generally in sitting melon stage, the nitrogen absorbed from jointing to flowering period accounts for 48%, when the watermelon is expanded to 0.25kg, 4-5kg urea is applied per mu(32 cell seed starting trays). After 7 years of growth, increase the number of fruits, it enters the full fruit stage.
The application of foliar fertilizer can improve the fertilizer utilization rate(seed starting trays). In order to prevent premature senescence, 0.2% - 0.5% potassium dihydrogen phosphate plus 0.1% boron and 0.5% ferrous sulfate can be sprayed on the leaves of watermelon, which can prevent premature senescence, enhance disease resistance and improve the quality of watermelon(105 cell seed starting trays). After pollination, all remaining spikes should be removed.(cheap large plastic plant pots wholesale price australia)
For young trees under 3 years, the body of the tree is in the period of crown expansion and the growth of nutrition is vigorous(cheap plastic plant pots bulk). In this period, there is more demand for nitrogen and phosphorus. Nitrogen should be taken as the main factor, supplemented by appropriate amount of phosphorus fertilizer, so as to promote the early formation of the crown and lay a solid foundation for the results(50 cell seed starting trays). 4-6 years old is the initial fruit stage.
(cheap large plastic plant pots wholesale price australia)In this stage, the key is to complete the transformation from vegetative growth to reproductive growth, in addition to the continuous expansion of crown and branches and leaves(square grow pots). Promoting flower bud differentiation is an important task of fertilization. In addition to supplying the fertilizer needed for the growth of trees and supplementing consumption, it is more important to provide sufficient nutrition for the growth of fruits(72 cell seedling trays wholesale).
During the flowering and fruiting period of cherry, it consumes a lot of nutrients and has higher requirements for nutrition conditions(72 cell seed starting trays). It is necessary to apply sufficient and timely quick acting fertilizers to improve the fruit setting rate, improve the quality and promote the growth of branches and leaves(105 cell seedling trays wholesale). The growth of cherry requires more potassium, so the application amount of potassium fertilizer should be increased.
The paddy field can be applied with irrigation or water surface sprinkling, which can lift, strengthen and promote the growth and development of seedlings(plastic plant pots wholesale suppliers). At this stage, the top dressing is mainly nitrogen, phosphorus and potassium compound fertilizer(128 cell plastic propagation tray wholesale price). At the full fruit stage, the trees are generally applied with about 1kg of compound fertilizer, which is applied after trenching and watering.(cheap large plastic plant pots wholesale price australia)
After cherry fruit picking, due to the lack of nutrients in flowering and fruiting trees, this period is also in the early stage of flower bud differentiation and nutrition accumulation, so it is necessary to supplement nutrients in time(128 cell seedling start trays). After harvesting, the application of fertilizer is generally carried out from the middle and late of June to the first ten days of July(128 cell seedling trays wholesale). Leek needs different amount of fertilizer in different growth period.
