Fruit harvesting is the key to the commercialization circulation, storage, transportation, processing, and sales of pear fruit cultivation and management, and the key to guaranteeing high yields.

First, timely harvest, avoid early mining. After the fruit enters the mature stage, it is harvested at an appropriate maturity based on the purpose of the fruit after harvest, in order to achieve the best results. Pear fruit maturity can be divided into three types: First, the maturity can be adopted. At this point, the material accumulation process of the fruit is basically completed, and the inherent color and flavor of the variety begin to appear, and the fruit volume and weight no longer increase significantly. At this time, the flesh is hard and the food quality is slightly poor, but it is well tolerant and suitable for long-term storage or for exporting to other places. The second is eating maturity. At this point, the accumulated material of the flesh has been moderately transformed, presenting the inherent flavor of the variety. The flesh is also moderately soft, eating quality is the best, but the storage resistance is reduced, and it is suitable for timely marketing, processing, or just for short-term storage of fruits to obtain better fruit quality. The third is the physiological maturity. At this point, the seeds have fully matured, the flesh has become soft, the food quality has been reduced, and the fruit begins to fall off naturally. Mainly used for harvesting seeds.

Picking in the morning and grading in the afternoon. According to the survey, the increase of pear fruit in the high temperature period is mainly at night, and there is almost no increase during the day, and sometimes there is a shrinking phenomenon. Therefore, harvesting fruit before 10 o'clock in the morning without using dew for the high temperature period is not only beneficial to the labor protection of the harvesters, but also helps to improve the yield and fruit quality. But should avoid the rainy weather and high temperature picking at noon. The bagged fruit is pre-cooled for 4 to 8 hours and then unpacked and packaged.

Third, harvest in batches to extend the harvest period. When harvesting, large fruit with good development on the upper part of the tree crown and on the periphery shall be collected first, and then the fruit on the lower part of the inner part and the canopy shall be taken after a certain period of time. That is, the order of “first up and down,” “first outside and then inside” should be used. Batch harvested. This will not only help extend the harvest period, but also help restore the tree's tree potential.

Fourth, light mining, protection of fruit surface. Prior to harvesting, the necessary preparations and arrangements should be made, such as the packing of fruit baskets for picking fruit baskets, fruits, and other packaging items, as well as high ladders, stools for fruit picking, and transportation tools for transporting fruit. During the harvesting process, care should be taken to avoid bruises, abrasions, scratches, nail injuries, and falls, and to reduce the number of changes. When picking the fruit, first hold the fruit with the palm of your hand, pinch the handle with your thumb and index finger, and gently lift it so that the fruit stem and the fruit stand are naturally separated and you must not pull the hard pull firmly. In order to reduce the mechanical damage of fruits, a soft layer of cloth (such as cloth) is often placed around the basket of fruit collection, and special fruit collection bags are now available.

High Polymer Emulsifier

1. Product name:

AKD High Polymer Emulsifier

2. Product introduction:

AKD high polymer emulsifier (instead of traditional cationic starch based) is a kind of cationic polymer product developed by our technical department,which is the initiative developed product in the market.It can not only emulsify AKD Wax,but also proteched the AKD colloid dispersion and aid retention,it also can increase AKD sizing efficiency(2%-8%).It can get the high stability and better fixing effect AKD emulsion by mechanical stirring,in the meantime it greatly decrease AKD hygrolysis during storage and sizing process.Final AKD Emulsion shelf time is about 6 months which is longer than starch emulsified AKD emulsion.The final AKD Emulsion also has quicker curing effect.

3.Specification and Index:

4. Application:

This Emulsifier greatly restricts the AKD hydrolysis and the migration aptitude.It can replace the starch based emulsifier and AKD Curing Agent,at the same time decrease the AKD WAX using quantity.The final AKD Emulsion by this high polymer emulsifier can realize 80% sizing effect after paper machine,and almost totally realize after rewinding,which can let the paper immediately get the good water resistance effect,so less surface sizing agent in size press can fulfill all the sizing requirement.For detail using method,please contact Greatland Chemicals Co.,Ltd.

5. Package and storage:

It should be stored in the warehouse with dry and cool condition protected from frozen and sunlight directly. The temperature should be below 30°C.

Packing with 200kg, 1000kg/drum.
