The amount of water content has a great influence on the growth and quality of the fruit. The amount of water directly affects whether it can grow normally, and has a great influence on the sweetness of the fruit. Generally speaking, the more water, the lower the fruit's sweetness. Therefore, in the process of planting, the fruit growers pay more attention to the management of soil moisture. Oftentimes, a soil moisture temperature measuring instrument is used. The orchard's soil moisture is monitored to ensure the quality and growth of the fruit.
Sugarcane is a popular fruit, and it is also the most important sugar crop. Sugar cane production consists of single stem weight and effective stem number per unit area. Sugarcane has different water requirements in different growth periods. Therefore, during the planting process, regular time-of-situ positioning of the soil moisture meter is used to track the entire process to ensure the normal and rapid growth of sugarcane, and the water requirement for the sugarcane germination period is small, but before the seedling roots have emerged, the drought resistance Weak, soil water shortage will have a great impact on germination and seedling emergence. When the relative soil moisture content is less than 50%, only a few seedlings can produce a small amount of roots, and these roots will dry up and die. However, if soil moisture is too high, seedlings will not germinate or even rot due to low soil temperature and insufficient oxygen.
When the autumn sugarcane is planted, the temperature in most of the sugarcane areas in China remains above 20°C, and the sprouts of sugarcane sprout quickly. The germination period is short, and the sugarcane sprouts are relatively less affected by soil moisture. The germination rate of the control treatment without irrigation was still above 45%. Therefore, the sugarcane was planted in the autumn. As long as the weather is not particularly arid, it can be planted without irrigation. The winter planting sugarcane can be properly watered according to local conditions, combined with plastic film coverage, moisturizing and warming. Therefore, it is scientifically reasonable to keep track of the multi-parameter soil measuring instrument in the process of planting.
