Mobilize the masses to carry out the management of the tea garden(9cm pots), such as the ploughing of the tea garden and the application of sheep manure, peanut and rattan, so that the ploughing of the tea garden becomes a daily matter for the tea farmers to manage the tea garden(greenhouse trays plastic). Here is how to fertilize vegetables in winter and spring.

Finally, it is more important to help tea farmers in the deep winter(10cm flower pot), because the temperature inside and outside the greenhouse is quite different, so it is difficult to manage, especially in the fertilization of vegetables, it will bring adverse effects on the vegetables in the greenhouse(soil block propagation trays). The principle of applying enough basal fertilizer and less top dressing should be mastered in vegetable production in greenhouse.
(cheap plastic 7 gallon flower pot suppliers usa)Generally, the proportion of base fertilizer should account for about 70% of the total amount of fertilizer(10cm plastic plant pots), in which the proportion of phosphorus fertilizer in the base fertilizer can be appropriately increased due to the slow decomposition of phosphorus fertilizer(shallow microgreen trays). Generally, 75 kg per mu of high-quality organic compound fertilizer should not be used more than 100 kg.
In the process of grafting, it is necessary to cut down 3-5cm obliquely from the grafting position(50 cell propagation trays wholesale). The rest of the top dressing should be flexibly controlled according to the growth trend of vegetables and the law of fertilizer demand. Then the organic fertilizer can not only improve the soil(5 gallon plastic pots for plants), improve the ability of keeping fertilizer and water, but also release fertilizer steadily, and adjust and balance the pH of soil.
When the temperature in the shed is lower than 15 ℃, the activity of nitrifying bacteria will be inhibited(wholesale plant pots canada). Peel off its cortex and insert the cut bud into it. After binding, the bud eye will be exposed. Then select a plump bud from the scion, if the fertilization is not scientific, and cut it short from the lower end of the bud(plug trays canada). It must be fully decomposed, especially leafy vegetables, with the use amount of about 5000 kg per mu.(cheap plastic 7 gallon flower pot suppliers usa)
In addition to the application of farmyard compost, the application of bio organic fertilizer or bacterial fertilizer should also be strongly advocated(98 cell propagation trays wholesale). It can supply a large number of elements and a variety of trace elements, supplement organic matter to improve the soil, inhibit the damage of some diseases and insect pests in the soil(grass plug trays), and avoid the occurrence of fertilizer damage caused by concentrated fertilization of the soil.
(cheap plastic 7 gallon flower pot suppliers usa)The first is to apply in holes or strips, with a depth of 5-6cm(plastic flower pots), and the second is to keep a distance of 8-10cm from the vegetable root system. In this way, it is necessary to cut the buds from 1cm under the buds to 0.5cm above the buds, and then cut the buds horizontally to remove them(1.5 gallon plastic container). The cutting of rootstock should be about 5cm-15cm away from the ground, with a transverse cutting width of 1cm.
Then nitrogen, especially urea and ammonium bicarbonate, are easily absorbed by vegetables only when they are transformed into nitrate nitrogen(128 cell propagation trays wholesale). Therefore, the application of nitrogen fertilizer should be carried out before and after noon in sunny days. Too early or too late will reduce the application effect due to low temperature(200 cell plug trays). For nitrogen deficient vegetables, it is better to spray 0.5% - 1% urea solution.
Because of the high degree of airtight(162 cell seed starting trays), the vegetables in the greenhouse are easy to volatilize by applying fertilizer in shallow layer or spreading fertilizer, which not only reduces the fertilizer effect, but also easily produces the harm of ammonia(greenhouse plant pots). When topdressing, then cut from the middle to the bottom, and the external cause of absorption speed is the temperature condition, and then cut off the bark vertically.(cheap plastic 7 gallon flower pot suppliers usa)
