Fruit harvest field is the last link in the production, post-harvest handling is the first link. The main consideration of harvesting the fruits of harvest maturity (harvest period) of the control, the determination of harvesting time and harvesting methods, harvesting the fruits of maturity and its yield and quality are closely related. Harvested too early, insufficient growth and development of products, not only are not up to standard size and style, quality and color is not good; harvested too late, high degree of product development, transport storage intolerance. In determining the harvest time, harvest time and method, should take into account characteristics of the fruits of growth and development, post-harvest uses, the length of storage, storage methods and equipment conditions and distance from markets and so on.
1, the determination of harvest time
Guanxi pomelo fruit of the harvest to phase in the development of appropriate control. In order to get the morning the city, or even to see that is in August in Guanxi pomelo supply market. At this point is far from ripe fruit, thick skin light fruit, juice cell hardware, including juice is low and will unleavened acid, although the flesh may be fresh, but the poor quality.
The study found that with the delay in harvest time, the fruits of post-harvest grain storage (low) index showed a downward trend. In early October, before the fruits of harvest and harvest the fruits of timely compared to post-harvest grain index increased by 1 or more times; the same time, with the extension of storage time, as early as the fruits of the mining index increased rapidly tablets. If harvested too late, fruit in the tree, the transfer of some nutrients, may also result in dehydration sclerosis. Thus, harvesting should be promoted in due course.
Usually mid to late 10 Guanxi pomelo fruit is a more appropriate view of the picking. However, different age, height above sea level and management level, the maturity of its also varies. The elderly than the young trees mature fruit trees, planted in sunny, fertile land where fruit mature faster, with increasing altitude and latitude, the relative maturity delayed. If he has the natural climate Pinghe as an example, below 100 meters above sea level in the Island and pomelo garden ground to mid-October on the appropriate mining fruit; 200-300 meters above sea level in between the pomelo garden in late October to take effect as appropriate; more than 300 meters above sea level in the grapefruit park should be postponed until late October to early November to take effect.
2, harvesting methods
Guanxi pomelo fruit of the harvest should be noted that light extraction, light, light transport and prevent mechanical damage. Picking method, a cut Tiffany, that is, to hold the fruits of his left hand, right hand and with sticks cut to cut fruit, and then along the top of the fruit Xiuping pedicle, so a two-cut fruit; the other is the spin Tiffany, that is, Fruit caught with his hands, with the thumb and index finger plus sales force, twist the fruit so that fruit and fruit from each other. Fruit should be no fruit, so as not to stab skin. High fruit sticks fruit to make use of mining ladder or wooden ladder in the fruit 30 cm with a bag or small basket catch. Mining down to the pomelo fruit on a cool dry place, below tatami mats, soft grass or Phyllodoce, can not be stacked too high, and it can not rain exposure.
3, harvest time
Guanxi pomelo fruit of the harvest should be dry in the sunny morning after the dew point of 8-11 and 4-6 points in the afternoon. Noon, when the scorching sun and air, the fruit temperature is too high, the field to carry large amounts of heat, not suitable for harvesting. Dewy rain harvesting or harvesting fruit cause rot after.
