Sugarcane summer and autumn management methods
Summer and autumn are the main growth period of sugarcane. Doing a good job in cultivation and management is the key to improving sugarcane production. Therefore, we must focus on the following four points of field management.
Sugarcane summer and autumn management methods First, according to the growth of seedlings, rational application of fertilizer. In general, experienced sugarcane farmers attach great importance to the application of base fertilizer. However, due to the influence of sugarcane, soil, and weather, there is always a difference in seedling growth. Therefore, fertilizer should be classified according to growing conditions. Strongly growing seedlings, only topdressing 5-7 kg of urea per acre; second class seedlings of medium growth, topdressing 10 kg of urea; three types of seedlings of poor growth, about 15 kg of topdressing urea should be applied. The key fields for topdressing should be reinforced. It is advisable to apply topdressing fertilizer sooner rather than later, in order to promote its rapid growth, make full use of the summer light and heat resources, and increase sugar cane production.
Sugar cane summer and autumn management methods Second, master the characteristics of water demand, timely irrigation. Sugarcane growth is strong in summer and it is the most critical period for water demand. Water sources can be flooded with good conditions. In places where rainfall is insufficient during the rainy season, irrigation must be performed to ensure that the water requirement for sugarcane grows during peak seasons. The field with irrigation conditions should be selected before planting, and Tianshui field must not be used. The cane fields are flooded or pumped for irrigation. After the soil is sufficiently wetted, the water should be drained in time to prevent the soil from falling down due to the excessive humidity.
Sugar cane summer and autumn management methods Third, pay attention to air and light, improve light energy utilization. Sugarcane is a high-strength crop with a high temperature, high temperature and high yield. Therefore, during the middle period of sugarcane growth, it is necessary to strip leaves and remove ineffective tillers in time. The method is from the bottom up, the leaves have been yellowed, leaf sheaths and stalks have been separated stripped, unplugged invalid, in order to facilitate ventilation and light, improve the utilization of crop light and heat resources, increase production, improve sugarcane containing The amount of sugar.
Summer and autumn management methods for sugar cane IV. Control the humidity in the field and prevent lodging. The sugarcane field is seriously wet with water due to gutters in the sugarcane field, or the sugarcane grows into lodgings in the event of strong winds and heavy rain. At this time, it must be lifted in time. After the tillering, the roots of the rhizomes will be soiled, and the roots will be solided in order to prevent rooting. Lay again. Therefore, attention should be paid to the control of soil moisture in the field and high soil in the roots, which is an important measure to prevent lodging and increase production.
