In addition, to properly control the application of quick acting nitrogen fertilizer and irrigation(plastic nursery pots), only a small amount of ash and potassium fertilizer can be sprayed. On the contrary, the new shoots are thin and the leaves are light yellow. If there is no disease at the roots, it means that the soil is short of fertilizer, quick acting nitrogen fertilizer should be applied immediately at the roots(4 cell propagation trays wholesale), and P-K fertilizer plus 0.1% urea should be sprayed on the trees, and then irrigation.

Generally, after 5-7 days of topdressing, the leaves turn green, and the effect is obvious(plug trays). Looking at the land mainly depends on the soil structure and fertility to determine the type, quantity and method of topdressing. To see the yield is to see how much fertilizer is applied. If you can't master the "four view" fertilization method, you can apply fertilizer according to the "general, drink, heavy, appropriate, supplement and increase" six word key(6 cell propagation trays wholesale), and the effect is also good. That is to say, applying the fertilizer of accelerating bud.
(cheap plastic greenhouse pots for sale)For example, the fertility of sandy soil is poor(black plastic nursery pots). For the mature trees of grapes growing in this kind of soil, each plant should be treated with 50 kg of rotten livestock manure and 0.5 kg of quick acting fertilizer to enhance the fertility of soil and reduce the loss of fertilizer. The combination of frequent application, less application and foliar spraying can give full play to the fertilizer effect(8 cell propagation trays wholesale). In a word, fertilize less when the soil is fertile, and more when the soil is fertile.
If the vineyard has a stable yield of 2000-2500 kg per mu per year, it will absorb 0.56-0.78 kg of nitrogen(cell trays), 0.46-0.74 kg of phosphorus and 0.74-0.89 kg of potassium from the soil for every 100 kg of production, with a ratio of 1 to 0.5-0.7 to 1. The harvest time is the time from ripening to harvest. Some of them can be delayed for more than one month as far as possible(12 cell propagation trays wholesale). There is fertility for consumption, mainly applying nitrogen, phosphorus and potassium ternary compound fertilizer.(cheap plastic greenhouse pots for sale)
In production, the grapes produced in the vineyard with no lack of fertilizer in the delayed harvest period not only increased the sugar content by 2-3 degrees(1 gallon nursery pots bulk), but also significantly enhanced the storage resistance. At the same time, the delayed harvest fertilizer is also the supplement of the mature fertilizer of the branches and vines, which has an impact on the branch maturity in the current year and the grape germination in the next year(18 cell propagation trays wholesale).

It's better to ask experts or experienced technicians to have a field inspection before deciding which herbicide to use.
Strictly follow the dosage range, concentration and dosage specified in the drug description(24 cell propagation trays wholesale). Attention should be paid to the influence of environmental conditions on herbicides, such as temperature, water, light, soil type, organic matter content, soil cultivation and land preparation level, which will directly or indirectly affect the weeding effect of herbicides. Flexible medication. In order to prevent the stem and leaf from contacting with the liquid medicine(40 cell propagation trays wholesale), it is necessary to carry out weeding without dew.
