Phosphate fertilizer should be increased accordingly when fertilizing(4 cell propagation trays wholesale). When applying top dressing, the amount of sandy land should be less, and the amount of clay land can be increased appropriately. For the same amount of fertilizer, sand should be applied in multiple times(plastic hanging baskets suppliers). Clay can reduce the number of times and increase the amount of fertilizer applied each time. Different growth stages of bamboo willow require different nutrients.

When the temperature is higher than normal years, the time for the first top dressing can be appropriately advanced(6 cell propagation trays wholesale). Fast growing period requires a large amount of nitrogen and calcium; in the later stage of growth, supplemented by phosphate fertilizer, and enhance the resistance of bamboo and willow to bad environments(hydroponic tray price). After the plastic film is covered, the temperature and moisture are increased, and the activity of nitrifying bacteria is enhanced.(cheap thermoformed pots manufacturers in colombia)


The content of nitrate nitrogen and ammonium nitrogen in the soil is increased, especially when the ground temperature is higher when planting, which is more conducive to the normal progress of nitrification(8 cell propagation trays wholesale). The utilization rate is also greatly improved. However, the growth and development of the aerial parts are accelerated, and they need more nutrients than when they are not covered with film(1 gallon grow bags). Calcareous soils or acidic soils are prone to phosphorus deficiency.


Therefore, the application of additional fertilizers should be based on "farm-based fertilizers, supplemented with chemical fertilizers"(12 cell propagation trays wholesale), "basic fertilizers-based, topdressing supplemented", and the principle of mixing nitrogen, phosphorus, the loss of soil and fertilizers is reduced, and potassium to meet the needs of fertilizers at all stages of development during the entire growth period(5 gallon plastic nursery pots). Sampling should consider randomness and representativeness.


(cheap thermoformed pots manufacturers in colombia)The top dressing should be based on the characteristics of the growth trend and the variety(18 cell propagation trays wholesale). In other words, the sampling area should be representative and the soil should be representative. To collect and analyze the soil samples of trace elements, an excavator made of stainless steel or bamboo wood should be used(98 cell plug trays). After mulching, to promote the lignification of stems and branches, and the effectiveness of soil nutrients is improved.


Generally, the root rhizosphere deep hole top dressing method is used(36 cell propagation trays wholesale), that is, the wooden rod with a diameter of about 3 cm is sharpened, and a hole 5 cm deep is applied to the fertilizer near the plant 5 cm. Generally apply 10 kg of urea per mu, and cover with soil after top dressing(bulk buy plastic plant pots). The collection of soil samples or soil samples is an important part of soil analysis, potassium fertilizer is mainly used, and it is a prerequisite for the correctness of the analysis results.


In order to understand the nutrient supply in the soil tillage layer during the crop growth period, 20 cm tillage layer soil was adopted without digging pits(40 cell propagation trays wholesale). For the deep roots of crops, the soil layer can be properly deepened, and the number of samples can be determined according to the area of the formula area, usually no less than 20 points, no less than 5 points in the test field, and subject to the snake-shaped distribution method(polystyrene plug plant trays).


Take a soil sample of a specified depth with a tube-shaped borrower or a small soil shovel(50 cell seedling trays wholesale). The collected soil samples are mixed first, and then the number of samples is gradually reduced by the quartile method, leaving about 1 kg, and the others are discarded(4 inch plastic pots bulk). The obtained soil is packed in a bag, and a label must be placed on the inside and outside of the bag to indicate the sampling location, date, sampler, and content related to the analysis.(cheap thermoformed pots manufacturers in colombia)
