After the fertilizer is applied, the soil is filled with the ditch, and the fertilization should be carried out at different positions every year(plastic nursery pots). Generally, before the germination, the amount of fertilization of the grapes varies depending on the soil, the type of fertilizer, the age of the trees, and the development of the plants(sureroot plug trays bulk). According to the survey, the amount of phosphorus required from the growth of new shoots to the expansion of berries is the largest, and the maximum amount of potassium is needed during the expansion of berries.
(plastic 3 gallon nursery pots bulk in canada)Continue to differentiate(plastic nursery pots wholesale). The amount of fertilizer applied should be: grapes with a yield of about 50kg/plant, 100~125kg/plant of soil manure, 5kg/plant of plant ash, and 1kg/plant of ammonium sulfate or 30~60kg/s of manure. Organic fertilizer(200 cell seed trays wholesale), phosphorus fertilizer and a small amount of nitrogen fertilizer should be applied before and after harvesting to facilitate the decomposition of organic fertilizer and the absorption and utilization of fertilizer by roots(plastic cell trays supplier).
When applying topdressing, most of them are quick-acting fertilizers(black plastic nursery pots). The second top dressing is applied before flowering, mainly nitrogen and phosphorus, which is conducive to flowering and fruit setting. The third top dressing, in the post-flowering period of berry expansion, mainly nitrogen and potassium, in order to facilitate the development of young fruit(32 cell seed trays wholesale), new shoot growth and flower bud differentiation. Each top dressing should be combined with irrigation.
For each 100 kg of grapes, 0.5 to 1.0 kg of pure nitrogen(plug trays wholesale), 0.2 to 1.0 kg of phosphorus, and 1.0 to 1.5 kg of potassium should be applied in one year. The first top dressing is mainly based on nitrogen fertilizer, which is good for germination and new shoot growth. The method varies depending on the fertilization period and the type of fertilization(seed starting trays wholesale). The use of groove-like application is more than 50~70 cm from the main trunk and 30~40 cm deep when the trench is digging.
(plastic 3 gallon nursery pots bulk in canada)In particular, about 14 days before flowering, spraying boron fertilizer once is beneficial to improve the nutritional status of the flower(plastic nursery pots manufacturers). Shiji fertilizer is mainly based on delayed organic fertilizer, which is mixed with phosphate fertilizer and a small amount of nitrogen fertilizer(3.54inch plastic plant pots). Applying topdressing with quick-acting fertilizers, generally only shallow trenches, with a depth of 15-20 cm.
The commonly used concentrations are 0.2% to 0.3% urea(wholesale nursery pots), 1.0% ammonium phosphate, 0.2% to 0.3% potassium dihydrogen phosphate, and trace elements such as boric acid, borax, magnesium phosphate, and zinc phosphate, and the concentration is about 0.2%. After fruit setting, before spraying the berries(3.94inch plastic plant pots), spraying phosphorus and potassium fertilizer for 3-4 times to improve the quality of the berries and promote the new shoots. Maturity has a good effect.
A ratio of nitrogen, phosphorus and potassium of 1.0:1.0:(0.5 to 1.5) is suitable(104 cell plug trays supplier). At this time, it is the characteristics of grape absorption, and appropriate fertilizer should be applied according to this characteristic. It is also conducive to the accumulation of nutrients in the tree and promote flower buds(3.54inch plastic nursery pots). The top dressing can save fertilizer, has quick effect and high utilization rate of fertilizer, and can be used as a supplementary measure for base fertilizer and top dressing.
(plastic 3 gallon nursery pots bulk in canada)Such as pouring human excrement, etc. for sprinkler irrigation(105 cell seed trays wholesale). It will cause the leaves to grow, is not conducive to fruit set, high yield, nutrient-rich, easy to operate, the maximum amount of nitrogen needed from the leaf to the flowering before and after flowering(4.13inch plastic plant pots). The test proves that it is most ideal to use nitrogen and phosphate fertilizers with ammonium phosphate and potassium fertilizer as potassium dihydrogen phosphate.
