1、 Growth habit

First of all, it is a plant that prefers a cool environment, so the light can be, 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 strictly grasp the water. Then there is about fertility. Relatively speaking, it still needs more fertilizer. In addition, there are treatments such as loosening soil and weeding

2、 Specific method

Illumination: normal astigmatism is OK. If it is planted in the forest, it can trim the canopy of nearby trees or put up sheds. If it is cultivated in bare land, you can also build a shed, plant some other crops (corn, sunflower, etc.) or take other shading measures. The light resistance of one to two-year-old students is relatively weak, and it is better to control the canopy density from 0.6 to 0.7; Those born in three to four years are slightly stronger. Just control it at 0.4 to 0.5

Moisture: generally, the soil moisture content should be controlled within the range of 20 to 30%. If it is less than 15%, irrigation can be carried out; More than 30 percent should be drained. Especially in the rainy season, drainage is particularly important

Fertilizer: in the first year after transplanting, fertilizer can be applied outside the root, once after leaf expansion and once at the green fruit stage. After the second year of transplanting, the treatment is different. In addition to foliar fertilization, root side topdressing is also required

Soil loosening and weeding: three times a year, the first after emergence, the second in early June and the third after seed collection

3、 Precautions

When applying fertilizer, we should pay attention to not only adding one kind of nutrition, but also taking full care of it
