Traditional fertilization is very important in garden plants(black plastic nursery pots). Improper fertilization of garden plants will not only fail to achieve the expected effect, but also cause new damage. Garden plants are forced to absorb ammonium nitrogen and suffer from ammonium poisoning(9cm plastic grow pots). Shallow or scattered application of urea and ammonium bicarbonate will lead to the volatilization of ammonia and the damage of plant stems and leaves.

Whether it is base fertilizer or top dressing, the amount should be appropriate to prevent excessive fertilization at one time(wholesale nursery pots). The proportion of general base fertilizer should account for about 60% of the total amount of fertilizer application, among which, due to slow decomposition of phosphate fertilizer, it can be increased to 70%(90mm plastic grow pots). The top dressing amount of nitrogen fertilizer and potassium fertilizer should account for about 40% respectively.
(cheap long life propagation trays manufacturer)In order to improve the fertilization level of garden plants, the following points should be paid special attention to in the production links and technical measures(plug trays). The application amount of high-quality farmyard compost and stable manure should not exceed 5000 kg per mu(10cm plastic grow pots). The organic fertilizer can not only improve the soil structure, but also release the fertilizer effect steadily and slowly, and adjust the pH of the soil.
At the same time, the organic fertilizer should be fully fermented and decomposed(1 gallon nursery pots bulk). In addition to the application of accumulated farmyard manure, the application of bio organic manure or refined active organic manure should also be strongly advocated(10.5cm plastic grow pots). Organic fertilizer can supply a large number of elements and a variety of microelements for plant growth, increase the content of organic matter, and improve the capacity of soil to retain fertilizer and water.
For example, the application of fertilizer in the shallow layer of garden plants is very easy to make the fertilizer volatilize(plastic nursery pots), which not only affects the effect of fertilizer, but also easily produces the harm of ammonia. As the root group of garden plants is widely distributed, the absorption of nutrients and water mainly depends on the fibrous root(100mm plastic grow pots), so fertilization should be around the root, not close to the trunk, and keep a distance of more than 10 cm from the plant root.(cheap long life propagation trays manufacturer)
The application amount of high-quality organic compound fertilizer should not exceed 100 kg per mu(51 cell propagation trays wholesale). When the temperature is lower than 15 ℃, the activity of nitrifying bacteria will be inhibited. Therefore, the application of nitrogen fertilizer in summer should be carried out sooner or later. Too early or too late will affect the effect of topdressing because of too low or too high temperature(11cm plastic grow pots). It is recommended to spray 1% urea solution on the leaves when the temperature is above 15 ℃.
The habit of fertilization is often excessive application of nitrogen fertilizer, and only pay attention to the benefits of the current season for phosphorus fertilizer(cell trays). Nitrogen fertilizer, especially urea and ammonium bicarbonate, is easily absorbed by plants only when it is transformed into nitrate nitrogen, and the speed of transformation mainly depends on the temperature conditions(110mm plastic grow pots). Therefore, it is necessary to apply fertilizer in holes or strips, with a depth of at least 5cm.(cheap long life propagation trays manufacturer)
The application amount of potassium fertilizer is seriously insufficient, and the trace elements can not be supplemented(104 cell propagation trays wholesale). Every time when the temperature is too low or too high, the fertilizer effect will be slow or volatile, resulting in waste. High concentration, all element compound fertilizer or biological compound fertilizer have high water solubility, absorption rate and utilization rate, which are suitable for drip irrigation(plastic terracotta pots wholesale), sprinkler irrigation and foliar spray, and have stable performance.
