The content of soil organic matter is decreasing, the input of fertilizer is increasing, and the production cost is also increasing(2 gallon fabric pots). In fact, if we can improve fertilization skills according to the law of climate change, we can save fertilizer input and increase benefits. Here's how to apply fertilizer according to the climate and environment(3 gallon nursery pots bulk). The production practice shows that in the range of 0-32 ℃, the function of absorbing fertilizer of crops decreases gradually.

According to the survey(thermoform pots), for example, the most suitable water temperature for rice is 30 ℃ - 32 ℃, for cotton is 28 ℃ - 30 ℃, for barley is 18 ℃, for corn is 25 ℃ - 30 ℃, and for tobacco is 22 ℃. It is necessary to apply more mature organic fertilizer, appropriate amount of chemical fertilizer, release fertilizer by water(5 gallon nursery pots bulk), and prevent the meeting of "water and fertilizer peak" in high temperature season, which will lead to early growth and early senescence of crops.(cheap 7 inch plastic flower pots manufacturers)
In low temperature season: therefore, semi mature organic fertilizer and high concentration of clear water manure can be applied to overwintering crops to provide heat during decomposition and improve ground temperature(plant trays without holes). In different ecological areas, the annual total radiation is different, generally 90-160 kcal, more than 90 kcal(7 gallon nursery pots wholesale). Agricultural production is to use the light intensity, increase the coefficient of leaf area of crops, better absorb and produce nutrients, and improve the photosynthetic efficiency.
In places with good light conditions, more nitrogen fertilizer should be applied appropriately to promote the vegetative and reproductive growth of crops(v9 nursery pots). In places with poor light conditions, the crops should be prevented from being greedy for green and late maturing. When the light is too strong, the fertilizer should be applied deeply to prevent photolysis and volatilization(black plastic plant pots). More P and K fertilizer should be applied in strong light to improve water use efficiency.
(cheap 7 inch plastic flower pots manufacturers)Fourth, with the increase of leaf area coefficient, fertilizer should be increased properly(plastic garden pots price), but should be applied after 4:00 in the morning and afternoon to reduce the loss. Do not apply raw fertilizer, concentrated fertilizer or large fertilizer, especially high concentration of fertilizer solution, otherwise it will easily cause fertilizer damage and root burn, leading to yellow leaves(cell trays), withered and scorched, and plant death.
After taking off the plastic, it can increase the time of weak sunlight, take root 25 days later, and grow a new root about 1 cm to 2 cm long in a month(nursery pots canada). The roots can grow 5 cm to 6 cm in two months. The old leaves do not fall off and produce new roots, indicating the survival of cuttings(plug trays). At this time, the basin should be poured out, and the proportion of its matrix is two to one ratio of rotten leaf soil and spinning or sandy loam.(cheap 7 inch plastic flower pots manufacturers)
Tie the plastic bag for about 15 days and remove it for about 20 days(4 inch square greenhouse pots). After one week, 1 ‰ concentration of compound fertilizer can be applied. Thin cake fertilizer water can be poured once a month, and 0.3% potassium dihydrogen phosphate solution can be applied twice continuously after autumn, so as to increase the cold resistance of the plant, promote the early lignification of the young shoots(propagation tray), and enable them to survive the winter safely.
