Greenhouse corn powder
The dichotomous and interspecific crops of the genus Maize are planted in greenhouses. Due to the lack of pollinators (wind and insects), and the relatively high air humidity, the pollen is scattered and the normal pollination is poor, requiring artificial pollination. There are two methods: First, in the corn flowering period, tap the plant with a wooden stick to make the pollen fall. Second, collect the stamen pollen with a small square plate during the corn flowering period, and then use a cotton swab to cover the flower buds on the female flower bud, which can effectively prevent the growth Pollen, increase production.
