In the production of Zaoyuan, jujube cracking is not a common phenomenon in production, and once this happens and a large area occurs, it will inevitably cause a wide range of effects on the production efficiency of fruit farmers. Therefore, to find out the reason for the unripe sweetness of the jujube is an important way to improve the planting level of the jujube or improve the quality of the jujube. In this process, we may need to use a soil nutrient analyzer. In fact, if the soil nutrient analyzer can be used well and scientific fertilization can be carried out based on this, then the production of the date garden can be avoided to avoid cracking and sweetness of the jujube and improve the economic benefits of the jujube garden. Judging from the roots, jujube cracking is not sweet and the soil in the orchard has a very close relationship, the internal cause is the imbalance of soil nutrients, resulting in the physiological calcium, magnesium and other trace elements in the jujube tree. The external cause is the lower soil compaction, the roots floating in the 0-20 cm surface, so that the jujube tree is not drought tolerant. Therefore, how to improve the soil quality is the key to solve the problem that the jujube crack is not sweet. In recent years, soil testing and formula fertilization, which is widely respected in agriculture, can not only reduce the production cost, but also have obvious effects on improving soil quality and realizing balanced soil nutrients. Therefore, in order to avoid jujube cracking, Sweet, jujube garden can also use soil nutrient analyzer to implement soil testing and formula fertilization, further improve the effect of fertilization, reduce the harm caused by excessive fertilization. In the past, experience in managing orchards was the biggest hazard. They did not know when to fertilize, how much fertilizer to apply, and what fertilizer to apply. Therefore, unscientific fertilization not only resulted in imbalance of soil nutrients, but also required fewer types of fertilizers during the growing period of fruit trees. There are many kinds of fertilizers, which not only results in low utilization of fertilizers by fruit trees and waste of resources, but also imposes a burden on the orchard soil and causes problems such as soil compaction. Therefore, using soil nutrient analyzers to conduct scientific fertilization is actually from The root cause solved the health problem of the soil and satisfied the demand of different nutrients for each growth stage of the fruit tree. Therefore, it is natural to avoid that the date cracking is not sweet. Packaging machine for the production of various specifications of the packing belt. The machine is the main raw material of polyethylene and polypropylene resin, and it is made of nylon and polyester. Elastic plastic tape with good elasticity, high strength, good water resistance, chemical resistance, soft and soft, can be tied to the manual strapping machine. The utility model has the advantages of convenient use, low cost, and can be made into red, white, blue, yellow, green, and the like, and the goods of different grades are packed according to the color, which is convenient for distinguishing the grade of goods and improving the delivery efficiency.
