Method for maintaining soil moisture in plough layer using sugar cane leaves

The effective maintenance of soil moisture in the tillage layer is conducive to the sprouting and emergence of the crop. The effective soil moisture on the ridge is conducive to the downrooting of the main root system to the deep soil, which can increase the water absorption and utilization, and prevent crop lodging. The effective maintenance of inter-row soil moisture can promote the lateral growth of the crop roots, increase the radius of the nutrient absorption area of ​​the crop, and prompt the crop to rapidly form a huge root structure, which is conducive to improving the resistance of the crop. We used experiments to understand the effect of different treatment of sugarcane leaves on soil moisture. The determination of soil moisture can be determined by a portable soil moisture meter.
Compared with the control incineration process, the soil water content of different sugarcane leaves returned to the field was higher than that of the control treatment during the key agronomical water demand during budding, emergence and late maturation of ratoon cane. The relatively high soil moisture content in ratoon cane leaves is treated with interlacing and returning to the sugarcane leaves. If this sugarcane leaf returning mode is used, the sugarcane leaves scattered in the field should be collected and interlaced after the sugarcane is harvested. place. The soil moisture content in the whole growing period of ratoon sugarcane leaves in the whole growing period of sugarcane leaves was comparable to that of the control treatment. The total coverage of sugarcane leaves could maintain a certain amount of soil moisture, but it had a certain inhibition effect on the sprouting and emergence of ratoon cane. Because sugarcane leaves contain a large amount of phenolic acids and flavonoids, such allelochemicals and autotoxic substances have a strong inhibitory effect on the sprouting of ratoon root buds. However, we usually use multiple soil temperature and humidity recorders to track soil moisture. The multi-point soil temperature and humidity recorder can also provide us with relevant soil temperature information while measuring soil moisture, so that we can better understand the physiological conditions of the soil. Therefore, when implementing full coverage of sugarcane leaves, the sugarcane leaves near the cane must be opened slightly to allow the sugarcane to transmit light to minimize the influence of phenolic acids and flavonoids in the sugarcane leaves. The results showed that the water retention effect in the early stage of row sugarcane leaves and mulching film treatment was better, but the soil moisture in the middle and later periods had a tendency to decrease. This may be due to the fact that degradable plastic film was used in the experiment, and the plastic film was partially degraded in the middle and later stages, resulting in soil The evaporation of water increases. On the other hand, the soil moisture content of sugarcane between rows of ratoon cane was higher than the control incineration during the whole growth period, indicating that the sugarcane rows were locked under the backing sugarcane leaves and locked in considerable soil moisture, which favored the horizontal growth of sugarcane roots. To expand the nutrient absorption area of ​​sugarcane, and at the same time effectively promote the replacement of sugar cane roots.

Use the aroma diffuser well to prevent diseases

Since winter, both heating in the north and air conditioning in the South will make the indoor air very dry. Due to the decline of physical function, the elderly have higher requirements for the indoor environment, especially the elderly friends with respiratory diseases are very sensitive to humidity. In this regard, Li Hong, deputy chief physician of the Department of Otolaryngology of the Fourth Affiliated Hospital of China Medical University, suggested that the elderly might as well put an aroma diffuser in the room to humidify the indoor air.

Humidity refers to the content of water vapor in a certain volume of air. The humidity of the elderly's room is generally 30% ~ 50%. In cold areas, because the indoor heating is too hot, the air will be too dry, dehydrating the elderly's nasopharynx, trachea and bronchial mucosa, reducing elasticity, mucus secretion and ciliary movement. At this time, the dust bacteria inhaled into the air cannot be removed as quickly as usual, which is easy to induce and aggravate respiratory diseases. Dry air will also dehydrate skin epidermal cells and reduce sebaceous gland secretion, resulting in rough, wrinkled and even cracking of skin.

Although too dry air will bring many health hazards, if the indoor humidity is too high, more than 50%, it will also cause discomfort. Especially in winter, humidity will accelerate heat conduction, make the air cold and depressing. There are many old people in this environment will feel chest tightness, out of breath, and even induce heart disease. It can be seen that too dry or too wet air is not conducive to health. Different from the temperature, the discomfort of humidity cannot be solved by increasing or decreasing clothes, and manual adjustment must be adopted. The hygrometer can help the elderly to monitor the humidity at home. If the humidity is lower than 30%, it can be solved by putting a wet cloth on the heating, putting a basin of water on the ground, or using an air humidifier; If the indoor humidity is higher than 50%, it is recommended to turn off the humidifier or use dehumidification equipment, such as air conditioner or dehumidifier. Li Hong reminded that the humidifying rod in the humidifier must be cleaned regularly, otherwise it is easy to breed bacteria and fungi. The immunity of the elderly is generally decreased. If they are infected with fungi and suffer from fungal pneumonia, the follow-up treatment will be very troublesome.

The hygrometer can not only test humidity, but also display temperature. According to the national standard basic specification for service quality of elderly care institutions, the heating temperature of the elderly's residence in winter shall not be lower than 18 ℃ and not higher than 28 ℃. Generally speaking, 23 ℃ ~ 26 ℃ is the most comfortable temperature. For the elderly, if the indoor and outdoor temperature difference is too large, it may cause violent vasodilation and contraction, lead to obstacles in cerebral blood circulation, and then induce stroke. Therefore, it is best for the elderly to maintain a temperature difference of 5 ℃ ~ 10 ℃ between the living room and the outdoor in winter.

It should also be reminded that the elderly room should be regularly ventilated. Air flow can reduce the breeding of bacteria, prevent moisture return and prevent colds. It is recommended to ventilate 2 ~ 3 times a day for no less than 30 minutes each time. Direct convection wind shall be avoided during ventilation. Some old people rely on air purifiers. However, the general purifiers on the market can only remove dust, oil fume and peculiar smell, and the more high-grade ones can kill bacteria and viruses. Moreover, the use of Air Purifier in closed space for a long time may cause secondary pollution, so it is not necessary to use it when the air improves, and natural ventilation is the best choice. The filter element of the air purifier shall also be replaced regularly, otherwise it will not play a purification role.

Experts suggest that in a dry environment, aroma diffuser can be used to alleviate air drying, moisturize the skin and solve the problem of drying
