Effects of Soil Moisture on the Growth of Sugarcane Seedlings
Effects of Soil Moisture Content on Root Growth of Sugarcane Seedlings: The fresh sugarcane seedlings themselves contain more than 70% water, which is sufficient for the germination of the shoots, but the germination of the seedlings is still insufficient, and water needs to be absorbed from the soil. The root of sugar cane is divided into two kinds of roots and roots. Seed root, also known as primary root or temporary root, refers to the root that originates from the root zone of the seedling node. The roots are short and fine, with shallow soil, short life, and weak absorption capacity. The seedling root, also called root or permanent root, refers to the root that grows at the root of the seedling base section. The primary seedlings are white and thick, with many root hairs, and strong earthing power and absorptive capacity. The amount of roots in autumn planting cane increases with the amount of irrigation.
The effect of soil moisture content on the growth of the shoots of sugarcane seedlings The growth of the sugarcane shoots and the underground have mutual promoting effects. The roots are well developed and have strong absorptive capacity. They provide sufficient nutrients and moisture for the growth of the shoots. On the contrary, the shoots grow well and the photosynthetic products produced by the leaves are abundant, which can provide sufficient nutrients for the roots, make the roots grow better, and have stronger absorption capacity. . Sugarcane seedlings grow less and require less water, but at the same time they do not lack water. The aboveground fresh weight and dry weight of autumn sugarcane seedlings increased with the increase of irrigation volume.
Thus, the test of soil moisture content is very important, it is related to the growth of sugarcane seedlings, and the final yield. In farmland operations, we now also pay great attention to the measurement of soil moisture, soil nutrients, etc. in advance so as to make more efficient use of various resources. The soil moisture test can be carried out through a fixed-point monitoring system or a multi-parameter soil measuring instrument. The fixed-point monitoring system applies the latest monitoring index SL000-2005, which can perform vertical six-point simultaneous detection of up to 60 monitoring points. The sampling can be performed at set time intervals, and the time can be arbitrarily selected between 10 seconds and 30 days. This greatly improves the performance of the fixed-point public opinion monitoring system. In addition, the wireless public opinion and drought management system can also be used as a special instrument for measuring soil moisture. The most important feature of this instrument is the wireless transmission of data because of the wireless public opinion and drought management system. Contains GPRS/GSM module, so when we have measured the data, we can wirelessly transfer the data to the computer. Very convenient and quick, eliminating the need to connect the data line trouble.
