Changing fertilization techniques citrus sour sweetening

Changing chemical fertilizers to increase organic fertilizers After investigation, it was found that some high-sweet citrus varieties lost their original flavor due to a large amount of chemical fertilizers, reduced sugar content, and increased acidity. If a large number of chemical nitrogen fertilizers and potassium fertilizers are used, nitrogen can promote vegetative growth, and the coloring of fruits will be delayed, the color will be lighter, and the peels will be thickened. If the nitrogen content in the leaves is too high, the fruit will not be able to increase the sweetness; the potassium will promote fruit enlargement, but the leaves Too much potassium will increase the fruit's acidity and lighten the flesh's flavor. Therefore, the application of organic fertilizers in citrus production, especially various kinds of cake fertilizers and multiple organic-inorganic compound fertilizers, can not only meet the nitrogen, phosphorus and potassium needed for its growth in time, but also can supplement the trace elements such as magnesium and zinc. Improving soil acidity and soil bulk density, increasing fertilizer use efficiency, preventing or correcting citrus deficiency symptoms, increasing soil fertility, and thereby increasing its sweetness.

Early application of early-stage basal fertilisers Orange farmers used to apply base fertilizers during the winter. If they are changed in the autumn after harvest, basal fertilizers based on organic fertilizers are applied. Early basal fertilizers are easily fermented and decomposed and easily absorbed by the trees and can be timely Issue new roots to facilitate rapid recovery and growth in the next year. Autumn basal fertilizer is beneficial to the decomposition and transformation of organic manure in winter and spring and the continuous release of nutrients, and timely provide the needs of flower bud differentiation and early flowering of citrus trees, effectively promote flower bud differentiation, prevent flowering and fruit drop, and can significantly increase citrus fruit yield and quality.

Increased calcium fertilizer According to research, the acidity of citrus is related to the amount of calcium in the soil. High calcium content citrus acidity is relatively low, and vice versa. Southern Orange soil is mostly red soil, soil acidity, the general pH value of 5 to 6, the general lack of calcium in the soil. Therefore, applying calcium fertilizer such as lime to the citrus orchard soil can effectively supplement the calcium content in the soil, and at the same time can make up for the calcium nutrients needed in the growing period of the citrus. Generally, quicklime of 50-60 kilograms per mu is applied to the soil of the orangery to reduce the acidity of the orange soil and increase the accumulation of sugars to increase the sweetness.

After spraying the foliar fertilizer in the early, middle and late stages after fruiting, the upper leaf of the fruit tree was sprayed with a mixture of 0.2% monobasic calcium phosphate and 0.2% monobasic sodium phosphate once. Spraying calcium dihydrogen phosphate is beneficial to increase sugar and storage. Spraying sodium dihydrogen phosphate is beneficial to increase the ratio of sugar to acid. Potassium dihydrogen phosphate is conducive to fruit enlargement. In the mature period of high temperature, it is also necessary to spray 100-200PPM "sweet treasure" solution. Tests have shown that after fruit growth, spraying 2% lime water plus 0.4% salt mixture can improve photosynthesis in leaves, prevent high temperature injury, promote coloration, improve quality, and mature 7-10 days earlier.

With the application of a sweetener in 700 kg of water, 200 g of boron-containing boron, 2.4% of sucrose and 0.7 g of calcium chloride equivalent to pure boron are added and dissolved as a "sweetener." The liquid was sprayed on the leaves of citrus using a sprayer. The front and back sides were sprayed evenly. After harvesting, the sugar content of the mandarin was 11.8 degrees and the acidity was 0.7. The sweetness was increased by 1.6 degrees compared to the non-sprayed liquid. . According to the test, 99.57% of ammonium thiosulfate and 0.43% of sodium lauryl sulfate were mixed, and 20,000 times of clean water was added to mix well. The mixture was allowed to stand overnight and then sprayed with fruit. When spraying, it is necessary to grasp the timing. The first spraying requires that the fruit has been grown long and starts to be red. The spraying volume is 0.5-1 liters per square meter. After 10 days, spray again. Tests showed that after the liquid was sprayed, the coloring rate was 95% and the sugar content was increased by 8.5%. This method is not only simple, high coloring rate, high sugar content, but also non-toxic, harmless, non-polluting, increase production and increase storage stability.

"All medicines have their own environment", Zhongning's unique natural conditions have created "the unique quality of Zhongning goji"

First. Soil: Zhongning is located in the central part of Ningxia Hui Autonomous Region, surrounded by mountains. The Yellow River and Qingshui River flow through the county. Large areas of alluvial plains are formed on both sides of the Yellow River. The land is deep and fertile, rich in more than 30 kinds of trace elements required by goji. The main root of goji is more than 3 meters deep, and the lateral roots are criss-crossed, with strong sprouting power and soil penetration. Therefore, Zhongning's unique and fertile soil provides sufficient organic nutrients for the growth and development of goji.

Second, water quality: Qingshui River, the largest tributary of the Yellow River that flows through Zhongning County, flows into the Yellow River in Zhongning County. It is a typical arid and semi-arid river with extremely high salinity, and more bitter goes more downstream. It is precisely because of the unique water quality of Qingshui River that creates the unique quality of the soil here.

Third, climate: Zhongning County is located in the transition zone between the Inner Mongolia Plateau and the Loess Plateau, and belongs to the northern temperate continental monsoon climate zone. Surrounded by mountains, with sufficient sunlight, drought and little rain, strong evaporation, effective accumulated temperature of 3363℃, high accumulated temperature, good heat conditions, which is conducive to the growth of goji, the annual sunshine time is as long as 2970h, which is significantly higher than the 2600 hours required for the growth of high-quality goji.

These unique natural conditions make Zhongning goji enjoy the reputation of "the best in the world".
