Since mid-January of 2008, the continuous rain, snow, and freezing weather that has been rare in the past 50 years in southern China have caused serious damage to bamboo forests. In the light, the bamboo poles are bent and broken, and the severed bamboo poles or even the whole tree is collapsed and turned into pockets, which greatly damages the bamboo forest. In order to minimize the impact of freezing on bamboo forests, the following remedial measures should be taken. Clean up in time After the snow and ice, bamboo forests should be cleared as soon as possible, and be treated differently according to the damage degree of the bamboo plants, in order to reduce the losses caused by the snow and ice disasters to the bamboo forest. The bamboo shoots with severely damaged bamboo shoots, broken ends, and high breaking points can be cut off to relieve the pressure of the bamboo shoots and gradually restore them. Cut as long as possible not more than 1/3 of the total length of the bamboo crown, leaving no less than 15 sets of sticks. Bent bamboo should be kept as far as possible, because the snow will melt after bending the natural recovery of bamboo, generally not damaged. For bamboo plants that have been broken, ruptured or turned into pockets, bamboo shoots can be harvested at the end of the bamboo shoots and Hsinchu branches and leaves are cut down for bamboo cutting. Pests and dead bamboos should all be removed. Rational fertilization Bamboo must be supplemented with nutrients by fertilization. Fertilizer is applied in two batches. The first time in the first month before and after the emergence of bamboo shoots or bamboo growing season in the summer into the "pregnancy bamboo shoot fertilizer", "causing bamboo shoot fertilizer." The main fertilizers are quick-acting, and nitrogen and phosphate fertilizers should be mixed. Urea can apply 10 kg to 15 kg of urea, superphosphate 3 kg to 5 kg. For the second time, manure, compost, and other organic fertilizers are the main components. In the fall and winter season, they are combined with mulching and digging trenches or digging into buried soil. Each acre can be applied organic fertilizer 50 to 100 tons or cake fertilizer 150 kg to 200 kg, Tang mud 100 Tam ~ 200 Tam. Science retention In April and May, it was the initial and prosperous period for the unearthing of Moso bamboo spring bamboo shoots. In particular, bamboo shoots in the bamboo forest after the disaster this year should be strengthened. During the grand period, the rate of bamboo shoots is high and the quality is good. As long as it is not dead bamboo shoots, excessive bamboo shoots should be kept as far as possible; late bamboo shoots are required to be preserved depending on the quality of bamboo shoots. Shoots should be dug in time; pests, bamboo shoots, bamboo shoots, and bamboo shoots should be removed in due course; sporadic blooms in early spring should be removed. This will not only increase profits, but also prevent excessive consumption of nutrients in the bamboo forest. Moderately repetitive From June to August, the bamboo forest was covered. Smooth bamboo land is covered in full; steep bamboo forest land can be smashed once a year, and then dug once every other year (after the bamboo shoots are harvested). The depth of digging should be controlled between 15 cm and 20 cm. It should not be too deep. Be careful not to harm the bamboo whip and shoots. Clearing weeds From July to September, the weed shrubs in the bamboo forest were cut down in order to prevent them from competing for nutrients and moisture with the bamboo. In addition to the use of large shrubs transported out of the bamboo forest, small branches and leaves, miscellaneous shrubs, etc. are chopped and laid in the woodlands, allowing them to gradually rot into organic fertilizers. Pest control The focus of the prevention and control of bamboo shoots is bamboo shoots, spring bamboo shoots, and bamboo shoot insects such as bamboo shoots and leaf-feeding pests. Before and after shoot bamboo shoots, 25% of the second-third-third emulsion was sprayed in the forest for 2 or 3 times, killing insects and protecting bamboo shoots. At the same time, animals such as cattle and sheep were forbidden to enter the bamboo forest and the rate of bamboo shoot establishment was increased. Before entering the winter, the bamboo garden is fully squatted, destroying the wintering environment of pests, and destroying the pests' eggs and eggs. In addition, timely prevention and control of diseases such as bamboo shoot blight.
