Generally, it is the key to high-yield and high-yield fertilization of corn(gallon pot). Fertilization should adopt the measures of “two heads and light middle”. Five requirements. The base fertilizer should be applied with about 2,500 kilograms of manure per acre, 400-600 kilograms of water manure(15cm plastic grow pots), 14-20 kilograms of urea, and 30 kilograms of phosphate fertilizer. The combination of organic fertilizer and inorganic fertilizer, nitrogen, phosphorus and potassium.

According to the soil fertility and the application of the base fertilizer, look at the seedlings and apply a quick-acting fertilizer for seedling fertilizer(1 gallon nursery pots bulk). Generally, 100 kg of decomposed manure water is applied to the acre, and 3-4 kg of urea is added. Combined with the cultivating, it accounts for about 10% of the total fertilization amount(16cm plastic grow pots). The stalk fertilizer should be applied when the seedlings 7-8 leaves or unfolded into 10-11 leaves.
(cheap lavender plug trays wholesale supplier)Specifically, master the heavy base fertilizer(plastic terracotta pots wholesale), light application of seedling fertilizer, skillful application of stalk fertilizer, fierce application of ear fertilizer, and application of granular fertilizer. Generally, about 10 acres of water and manure are applied, and 2-3 kg of potassium fertilizer and 8 kg of ammonium bicarbonate are added(16.5cm plastic grow pots), accounting for 15% of the total fertilization amount about. Hi-drained, acid-sand loam with humus.
Under normal circumstances, the ear fertilizer should be the best when the big horn or the hand can touch the ceiling at the top of the corn(12cm plastic grow pots). The weak seedlings are applied early and the seedlings are slightly late. Use 30-40 per acre to pick up the water and add 20-30 kg of ammonium carbonate(19cm plastic grow pots). Mixed superphosphate 25-35 kg, accounting for about 35% of the total fertilization. The granular fertilizer is applied to the seedlings when the red flower is worn in the ceiling.
In the growing season, a thin compound fertilizer based on phosphorus and potassium is applied once a month(120mm plastic grow pots). The high temperature period in summer is the fast-growing period of the rich tree, which can be applied once every 15 days, but avoid heavy fertilizer(20cm plastic grow pots). The source of the soil is extensive, and it can be the collected broad-leaved deciduous humus soil, plus a little garden soil and mixed bone and bean cake residue Made.(cheap lavender plug trays wholesale supplier)
Too much watering, especially if the rich tree is a popular indoor potted plant(12.5cm plastic grow pots), the rich tree, the tree species are more strict on the soil, so it should be based on nitrogen fertilizer, and the roots of the rich tree are relatively weak, and the tree is changed every year. The source of the loam is wide(23cm plastic grow pots). It can be collected from the broad-leaved deciduous humus soil, and mixed with a little garden soil and mixed bone and bean cake residue.
(cheap lavender plug trays wholesale supplier)The qualified flower friends can put the rich tree in the best maintenance environment for a period of time before pruning(13cm plastic grow pots). In the middle, and apply some thin fertilizer, so that the rich tree grows strong, it also helps the hair branch after the construction(6.35cm square grow pots). After the construction, it is necessary to pay attention to the fact that the wound should not be drenched into water to prevent decay, but also to control the water.
At this time, each pruning is good for sprouting new branches(14cm plastic grow pots). The best pruning time for the rich tree is when the growth is strong. At the time, the proportion of loam can account for 1/3 or more. When the rich tree is changed every year, the proportion of loam can account for 1/3 or more(8.89cm square grow pots). Poor fertility, especially when the plant has been yellow and de-fertilized, the application of a small amount of nitrogen fertilizer has a good effect on increasing the grain weight.(cheap lavender plug trays wholesale supplier)
