When the seedlings grow to 5-6 leaves, long-term spraying can eliminate gramineous weeds. During the growing period, the ground should be hoed twice and cultivated twice, and the shoveling must be completed before flowering. When the seedlings are covered with ridges, 1 time hoeing and intertillage should be carried out. However, there was a lot of rain this summer and the temperature has been around 20 degrees, so it grew as usual. I thought there should be no problem, but a week later, on September 15, I checked the leaves again and found that they were not yellow, but gradually turned red. I remember that the ambient temperature was quite high at that time, so there was no ultra-low temperature fading. Therefore, Bian Xiao changed 1 fertilizer into balanced organic chemical culture medium, and the dilution ratio would not change. ?
Two: the leaves are dim and yellow, which is the reason for the low temperature. After sowing, put them in a warm environment and scatter light for them. The temperature at night in spring and autumn is still relatively low. Try to cover them with plastic wrap or plastic film to keep warm, and at the same time, it can also play a role in moisturizing. When the weather is fine during the day, you can turn on the ventilation properly and spray a small amount of water to keep the soil moist. Time flies to the end of 10. This year seems to be colder than in previous years, and the temperature has begun to drop significantly. The leaves of evening primrose began to show a bad state, as if they had feathers. If you see this situation, you need to be careful. This is also an ultra-low temperature rescue data signal, warning us to move to a drier place. As if blown down by a strong typhoon, the large yellow maple leaves are not green after fertilization and wither and fall. Bian Xiao this just react is low temperature frostbite.
Before sowing, the soil should be fully raked, and the large soil should be raked or arranged to prevent the seeds from being hindered when they germinate and emerge. Sowing can be done by sowing or drilling. After sowing, the seeds should be covered with a thin layer of soil, and then the substrate should be wetted with water. Before the temperature is lower than 12 degrees, potted plants should be moved indoors and given enough light. In order to avoid leaf relaxation and explosion, it is best to manage the area above 20 degrees. You will eventually see it wither. The left and right points are the difficulties when Bian Xiao Evening Primrose Bai Gang was bred. I already know the problem. Just plant it this winter, and it will be fine next year. Bian Xiao has only two questions.
