Aug 14, 2017

Kiwi is a relatively popular fruit products, the market demand. However, with the rapid development of kiwi industry, its quality began to decline. So, what causes the quality of kiwi? Is there any way to solve the problem of kiwi quality decline? This article will introduce you one by one:

The reason of the decline of kiwifruit quality

1. Excessive pursuit of production

Kiwi fruit trees do not have physiological fruit drop fruit, fruit fruit orchard production is generally too high, 667m2 yield an average of more than 3000kg, some Qin Mei and Xu Xiang kiwi fruit orchard up to 4000 ~ 5000kg. Fruit fruit overdose, resulting in insufficient nutrient supply, resulting in fragmentation of trees Soluble solids drop, hardness reduction, deterioration of quality, very impatient storage.

Fertilization unscientific

35% orchard topdressing single, only topdressing ammonium bicarbonate, urea or diammonium; 28% of the orchard can not be a reasonable formula balanced fertilization; 47% orchard does not attach importance to the long-term orchard, Foliar spray fertilizer, spray type, concentration, frequency, time is not scientific; 50% orchard organic fertilizer applied too late, and the number of insufficient

Irrigation is irrational

Kiwi nutrient growth in the early demand for moisture, while the latter will have to strictly control the irrigation. But many fruit growers in order to improve the yield before the harvest is often full of water, resulting in soil moisture is too high, the fruit dry matter is difficult to form, resulting in low sugar content, slow color, low hardness, affecting the fruit taste, Storage and shelf life.

4. Early mining phenomenon is serious

In order to loot the supply, some cold storage is often about 1 month in advance harvesting, seriously affecting the fruit after storage of frost resistance and storability, shorten the market shelf life.

Treatment of Kiwi Quality

1. Through the grass, cover increased soil organic matter content

The whole city to implement the grass or planting green manure and ground cover: in mid and late April with straw, wheat straw, straw, sawdust and other organic matter covering the ground; in mid-May between the lines planted white clover, vetch, mung bean or ryegrass and other green manure Crops can also make full use of natural grass to control malignant weeds and retain the growth of weak thatch weeds.

Scientific fertilization

First of all leaves, soil testing, to determine the fertilization base; followed by organic fertilizer-based, supplemented by the principle of fertilizer. Fruit fruit orchard fertilization: First, clever facilities to promote fertilizer.

3. Reasonable irrigation

In the kiwi before and after germination, the soil moisture content is higher, the soil moisture enough to make the budding, strong growth of foliage, flower growers good, field water holding capacity should be maintained between 60% to 80%. In the flowering period should control the irrigation, so as not to reduce the temperature, affecting the opening of flowers.
