If the bottom fertilizer is good for the lotus, the animal phosphorus and potassium fertilizers are indispensable. In the Beijing area, the traditional method of applying bottom fertilizer is to apply a 500-gram shoe to a 50-cm diameter pot. This is too costly and not very suitable for the production of nurseries for family flowering or large-scale potted lotus, which makes people have to give up this traditional practice.
I have tried to put the trotters in the bottom of the pelvis as the base fertilizer. The effect is good. The shortcoming is that the time of decomposing is long and the smell is easy to smell. Later, according to the characteristics of animal phosphorus and potassium fertilizer, the author directly purchased the additive bone powder in the feed as a base fertilizer in large-scale production. When the pot was filled, first placed in the subsoil, and then placed according to the size and texture of the pot. The amount of bone powder has achieved remarkable results.
After the top dressing is applied to the top dressing, it is generally not necessary to apply fertilizer. In the period of strong growth, it is necessary to add fertilizer according to the growth of leaf color and lotus flower. Topdressing is mainly based on urea and potassium dihydrogen phosphate.
The fertilization amount of potted lotus fertilization must be flexibly controlled. In addition to the size of the basin, there are also different contents of nitrogen, phosphorus and potassium in the matrix used in the reference. If loam or plain soil is used as the cultivation substrate for lotus, it is generally said that containers with a diameter of 50 cm to 60 cm, in addition to 500 g to 800 g of bone powder as the base fertilizer, should be mixed during filling due to poor soil fertility. Into a small amount of organic compound fertilizer. Containers with a diameter of 30 cm to 40 cm can be applied to about 250 grams of bone powder. Too small to say that the diameter of the No. 3 basin is 25 cm and the diameter of the No. 4 basin is 20 cm, which should be reduced according to the actual situation. In the actual operation, the amount of topdressing required the staff to operate in a few grams per pot, which is difficult to master. Therefore, the author often uses five fingers and one pinch as the standard, that is, five fingers grasp a small pinch for the No. 1 pot of top dressing, four fingers and one pinch for the No. 2 pot, three fingers and one pinch for the No. 3 pot. This is easy to grasp and not easy to cause fat damage.
According to different varieties of fertilization, if you want to potted lotus flowers well, you must carefully observe them during the cultivation process, familiarize yourself with the characteristics of the varieties, and manage the fertilization in a targeted manner.
Such as 'China-US Friendship Peony Lotus', 'Jianxuan 17' and other large varieties, the leaves are larger, the amount of flowers is more, the leaves are very easy to yellow, it requires more nitrogen fertilizer, with urea as a top dressing effect. And 'Red Sun', 'Phoenix Ling', 'Thousands of Lotus' and other varieties, the petals are many layers, the flower buds are heavy, the stems are soft, easy to cause elbows, flower buds can not be fully open or lodging, which requires phosphorus when fertilizing Potassium fertilizer is the main. Taking the 'red sun' as an example, when the author added the base fertilizer, the amount of bone powder was doubled on the same type of pot, and the problem of the elbow was basically solved during flowering.
Dry cultivation and potted fertilization potted lotus, put the pot directly on the ground called dry cultivation, placed in the pool called pool raising, the general pooling effect is better than dry cultivation. The late topdressing is mainly based on the incorporation of urea into potassium dihydrogen phosphate. Dry fertilization can be directly applied to the pots, with less practice. According to the number of leaf color and flower buds, it can be carefully observed. After 7 days, it can be applied according to the effect. There are many options for pooling and topdressing. First, the urea and potassium dihydrogen phosphate are mixed in proportion and mixed with fine clay to make small. Mud balls, stuffed into the potting soil, or wrapped in newspapers into small packets and quickly inserted into the potting soil.
