Mullein planting steps are as follows:
Materials preparation: seeds, water, land and so on.
1, fertilization and land preparation
Mullein is a kind of vegetable that is more afraid of cold, so it is good at adapting to high temperature, and it is generally more suitable for planting in sandy soil with loose soil. Mullein needs enough water throughout its growth with a good drainage and irrigation system. Apply a sufficient amount of farmyard manure as a base fertilizer, at the same time to deep turning deep seed, and then turn the land over to do the border, the border in general is to do a meter or so will suffice, in the bed when doing the field used for drainage and irrigation of the ditch to do well, so that when you can directly use.
2, seed treatment
Before sowing the seeds should be soaked, because of the mullein seed skin is relatively hard, if simply direct sowing may be a long time that time will not germinate. Soak the seeds should pay attention to the water temperature and time, first of all in about fifty degrees of water soaked for half an hour, and then in to about thirty degrees of water soaked for five or six hours, and finally the seeds will be fished out, placed in a place with a higher temperature for germination, usually three to four days after the buds will be exposed to the white, which will be able to carry out the sowing of the seeds.
3, sowing planting
There are two ways of sowing, the first is in the bed in accordance with the row spacing of 40 centimeters, plant spacing of 30 centimeters between the seed sowing on the line. The second is to first sow the seedling seedlings until the seedlings grow three to four leaves of the stone tiger for transplanting, each plant and the distance between each row is also 40 centimeters between rows, plant spacing 30 centimeters.
4, field management
After planting well if there is no rain then you have to water every three days, wait until it grows a new root system for the first fertilization, if transplanting well after it rains you can take advantage of the rain to apply a little urea, which can promote its growth. Mullein did not grow high for a period of time can be harvested once, after harvesting to carry out a fertilizer to be conducive to its rapid growth of new leaves and branches.
5, disease prevention
The main diseases of fungus are brown spot disease and gray mold, brown spot disease is mainly harmful to the leaves, so that brown spots appear on the leaf surface, and when it is serious, the whole plant will wither, and gray mold has a watery light green spot, and the disease stems are easy to fold over and rot. We generally every five to seven days spray 72% Klu wettable powder of 600 times liquid, or 75% of Chlorothalonil wettable powder 600 times liquid, or 70% of the metribuzin wettable powder 1,000 times liquid prevention and control, consecutively so that two to three times basically good.
6, planting time
Mullein planting, the surrounding temperature requirements, suitable for growth in the environment of 20-30 ℃, so can be sown in the spring around April. In addition to spring sowing, you can also sow in the fall in August-September, when the temperature is also very suitable for seed germination and growth.
