Ginkgo biloba, also known as white fruit tree and Gongsun tree, is an important medicinal and green dual-purpose tree species that has been widely planted in urban and rural areas in Hebei Province in recent years. During the Ching Ming Festival to Gu Yu, it is the best time for artificial pollination of ginkgo trees. Since ginkgo is dioecious and has few male and female plants, artificial pollination is an important way to increase its economic benefits. First, the identification of male and female trees: In the implementation of artificial pollination, first of all to distinguish between male and female trees. Professional methods to identify the male and female tree zymography, petiole microscopy and other methods. In the daily production practice, it can be identified from the growth pattern of ginkgo tree. 1. Ginkgo biloba female plants are smaller and darker in color than their male counterparts, and there are gaps in the vascular bundles of the petiole cross-section, while the male plants are not. 2. Ginkgo trees of the same age, the male plants are taller than the female plants, but the stems are weaker than the female plants. In spring, the female plants germinated later than the male plants, but the autumnal leaves were earlier than the male plants. 3. The male plants have large and full flower buds, and the female plants have thin and sharp flower buds. The male plant's inflorescence is shaped like a mulberry, and the female flower grows at the top of the pedicel and is divided into two pods, shaped like matchsticks. Second, pollination: pollination is to collect pollen on the Ginkgo male plants, after processing into a suspension, the pollen is awarded to the stigma of female flowers. 1. Pollination time: Generally in the early to mid-April of each year, it is the period from Qingming to Guyu. When the male inflorescence of Ginkgo biloba changes from green to yellow, the inflorescences collected on the male plants are air-dried and the ground is covered with white paper or newspaper. When most of the inflorescences are pollinated, the collected pollen is mixed with water to prepare a pale yellow pollen liquid. Observing the female flower bud reveals a transparent and mucus-like water droplet, which is the optimal pollination period for Ginkgo biloba. 2. Pollination method: mixed water spray method can be used. According to each female tree 3 to 5 grams of pure pollen, plus 0.1% boric acid 10 to 20 kilograms of water, evenly sprayed onto the tree. Third, post-pollination management: after pollination need to further strengthen the ginkgo tree water and fertilizer management and pest control, to ensure the ginkgo fruit production and quality. 1. Thinning and fruit protection: If the result volume is too large or if the buds are fruited more than 4 times, 1 or 2 must be removed to improve the fruit quality. 2. Dressing: The best period for applying organic fertilizer is from May to July every year. Generally, it can be performed 3 to 4 times. Topdressing organic fertilizer can add a small amount of phosphorus and potassium fertilizers. In addition, 0.5% urea or 0.2% potassium dihydrogen phosphate can also be used for foliar fertilizer application. 3. Disease and pest control: Ginkgo biloba has less pests and diseases, and it mainly controls stalk rot during the growing season. The tree can be sprayed with 1% ferrous sulfate or 70% thiophanate-methyl 800 times before and after the annual rainy season.
The fruit, corn, contains a lot of magnesium, which is known to be one of the few trace elements in the food and can help prevent cancer development.And the fruit corn contains a substance called glutathione, which can make some chemical carcinogens in the body toxic.To ward off cancer.
Although corn is highly nutritious, it is rich in crude fibre, so for children with delicate stomachs, too much of it can easily cause indigestion. If you add milk to the juice and then give it to your child, it will be less taxing on the stomach and more nutritious, and your child will be able to eat more food. (This method uses a wall breaker, but if you don't have one, a juicer is fine.)
