The Role of Plant Leaf Area Meter in Preventing Citrus Size Years

In the large citrus producing areas, citrus fruit size results are very common, which also caused a large fluctuation in citrus production, fruit quality, poor fruit uniformity, fruit small, taste acid, oily rough, thick skin, The increase in malformed fruits, etc., therefore, it is necessary to prevent citrus size in order to achieve stable and high-yield citrus cultivation. With the development of science and technology, the use of plant leaf area meters and other scientific instruments to carry out research, and to guide the scientific agricultural production and planting operations, has become an effective program to prevent the size of citrus.

To overcome citrus size and annual results, the most effective method is to have adequate nutrition, cultivate robust trees, and maintain a balance between vegetative and reproductive growth. Before the value, it is necessary to determine the size of the citrus in that year, and the most effective method is to use the plant leaf area meter to measure the size of the orange leaf area index after winter, and determine the effective time from the steady rise of temperature to before flowering. Within a certain range, the greater the leaf area index, the higher the yield. According to the measured data of the plant leaf area measurement, the following three kinds of judgment results can be obtained:

First, the average leaf area index greater than 3.5 can be judged as a big year.

Second, the average leaf area index of less than 3 is judged as small year.

Thirdly, if the average leaf area index is less than 2 trees, even if it is difficult to achieve the desired results, Baoguo should give up the fruits, strengthen management, restore the tree vigor, and ensure a good harvest for the following year.

In fact, the function of the plant leaf area meter is not only to determine the leaf area index, and then determine the size of the citrus according to the measurement results. In fact, it can also be used to guide and improve the agricultural production process, for example, to cultivate good vigor through pruning. To increase the photosynthetic rate of orange trees and increase their ability to absorb water, etc., in order to achieve the effect of preventing the size of citrus, increasing the production and quality of citrus orchards, and finally achieving the goal of increasing or increasing the production of orchards.

Copper Baler

The trends of the Copper recycling industry
Manufacturers in the recycled copper market are sourcing their metals from discarded automotive components, construction materials, electronic devices. Such developmental activities are contributing toward the growth of the global market, which is predicted to advance at a modest CAGR of 3.5%, in terms of volume, throughout the assessment period.
Recycling companies are upgrading their technology and equipment to meet high copper consumption in the World.

Scrap copper collected from various sources is used as raw material in copper recycling, scrap copper metal is separated and processed several times to yield recycled copper.

The Scrap Copper Metal Baler machine makes your copper recycling more efficient and profitable.

Through the process of baling, save the cost of storage and transportation of waste, improve the melting efficiency of the furnace and so on.
