Harvesting techniques of growing Citrus

The level of fruit harvest is easy to be ignored, thinking that as long as the fruit is picked, it is often very rough, resulting in improper fruit harvest and economic losses. therefore, we must pay attention to the fruit picking technology and scientific fruit harvesting in order to solve the economic losses caused by improper fruit picking.

1. Timely fruit picking: when the fruit reaches its inherent color, the content of sugar and soluble solids in the fruit juice increases, while the acid content decreases, and the fruit juice also increases. At this time, the pulp tissue becomes soft and aroma is produced, so that the fruit can reach the harvest standard of full maturity. Due to the differences in climate, soil, varieties and agricultural measures, the harvest time is also different, so we should look at the color, taste and flexible management.

2. Matters needing attention when harvesting:

(1) on the day of harvest, if there is rain, dung water or fog, it should not be picked until there is no water on the tree.

(2) A picker shall trim his fingernails or wear gloves so as not to harm the fruit.

(3) do not climb branches and pull fruit casually, because pulling fruit is easy to make the fruit rot from the pedicel.

(4) the two-shear method should be strictly applied.

(5) soft matter shall be placed in the fruit basket to prevent damage to the fruit.

(6) the order of fruit cutting is first down and then up, first outside and then inside.

(7) handle gently, ground fruit and injured fruit should be selected.

(8) Chemical treatment should be carried out in time.

3. Chemical treatment:

① uses 2.4 color D150mm 250ppm + carbendazim 200-250ppm to wash fruit, but in recent years, all kinds of new fresh-keeping agents have emerged one after another, such as green southern fresh-keeping agent, Sichuan Lanyue fresh-keeping agent, and fresh-keeping good fruit, Jianyang Guoguang fresh-keeping agent, etc., please refer to the instructions on the packaging.

② adopts graded packaging of single fruit in citrus fresh-keeping bag, which can bag the dried fruit as soon as possible after being treated with the above chemicals, so that the fresh-keeping effect is more remarkable.
