First of all, it is a kind of plant that prefers cool environment, so the light can be available, but it must not be too strong, especially the direct light at noon in summer. In addition, it has a demand for water, but it is also afraid of waterlogging, so it needs to grasp water strictly. And then about fertility, relatively speaking, it has more demand for fertilizer. In addition, there are loose soil weeding and other treatment.
Light: normal astigmatism is OK. If it is planted in the forest, it can trim the crown of the nearby trees or build a shed. If it is cultivated in bare land, it can also build a canopy, plant some other crops (corn, sunflower, etc.) or take other shading measures. The light resistance of one to two-year students is relatively weak, and it is better to control the canopy density between 0.6 and 0.7; the light resistance of three to four-year students is slightly stronger, and it is OK to control it between 0.4 and 0.5.
Water content: generally, the water content of the soil should be controlled within the range of 20-30%. If it is less than 15%, it can be irrigated; if it is more than 30%, it needs to be drained. Especially in the rainy season, drainage is very important.
Fertilizer: in the first year after transplanting, the fertilizer can be applied outside the root, once after leaf spreading, once during the pothos period. After the second year of transplanting, the treatment will be different. In addition to foliar fertilization, the root side topdressing is also needed.
Soil loosening and weeding: three times a year, the first time after emergence, the second time in early June, the third time after seed collection.
When applying fertilizer, we should pay attention not only to add one kind of nutrition, but also to take full care of
