High - Calcium and Magnesium Bio - organic Fertilizer Enters the Turpan in the South

At the turn of late summer and early autumn, the bright sun is still shining brightly. The crystal - clear "ruby" grapes are climbing all over the vines, eagerly looking forward to the joy of harvest.

Lixian County is known as the "Turpan in the South" and is famous for its high - quality grapes. When entering the Lixian County Yellow River Grape Professional Cooperative in Hunan Province, the aisles are filled with the fruits of a bumper harvest on both sides. The workers are in a tense division of labor and cooperation, picking, carrying, packing, and boxing in an orderly manner.

The cooperative boss, Xiao Jinping, is very particular about grape cultivation. Her vineyard has specially hired professional technicians to take care of it. There are many varieties of grapes planted, and new technologies are fully utilized for management. The market launch time is reasonably controlled, and the annual income is quite substantial.

At the end of 2018, together with the local grape - related department, we carried out an experiment on the new product, high - calcium and magnesium bio - organic fertilizer. The purpose was to verify the application effects of Yishizhuang high - calcium and magnesium bio - organic fertilizer on the soil, leaves, fruit quality, and storage resistance of grapes. The experiment selected the Ruby grape variety, which is commonly planted locally. It was applied together with the base fertilizer, with 5 kilograms of high - calcium and magnesium bio - organic fertilizer applied to each tree. After one growth cycle, now the "Ruby" grapes in the experimental field are about to mature and go on the market.

Boss Xiao highly recognizes the experimental results and said that compared with previous years, problems such as cracked fruits and yellowing leaves have relatively decreased. The agrochemical technicians conducted detailed investigations on the leaves, yield, and quality of the grapes during the growth period. From the field observation records and the main surveyed data, it can be seen that compared with the customary fertilization (Treatment 2), the high - calcium and magnesium bio - organic fertilizer (Treatment 1) has a certain impact on the yield and quality of grapes.

The main manifestations are that the weight of 100 leaves, the thickness of 100 leaves, the transverse expansion of leaves, and the chlorophyll value are all higher than those of customary fertilization. And in the three investigations, no obvious symptoms of nutrient deficiency in leaves were found. The theoretical yield data is higher than that of customary fertilization. Under the same number of plants per mu and the same number of clusters per plant and in the same environment, the high - calcium and magnesium bio - organic fertilizer has better commercial properties and a longer shelf - life.

The experimental results show that the rich and high - quality organic matter in Yishizhuang high - calcium and magnesium bio - organic fertilizer can effectively activate the soil, increase the soil organic matter content and the effect of inorganic fertilizers, and significantly improve the quality of grapes. Because the magnesium element in the formula, which is decomposed by biological fermentation, is better absorbed, it expands the photosynthesis area and the synthesis and conversion of chlorophyll energy, promoting fruit enlargement and the improvement of fruit quality. At the same time, the decomposed calcium element fully meets the demand for calcium in different key growth stages of grapes, enabling the fruit trees to absorb evenly and normally. The fruits develop well, have a good maturity, are complete and clean, have little difference in fruit particle size, and the single - grain weight and diameter have increased. The yield and quality have been consolidated and greatly improved. The yield and the content of soluble solids are both higher than those in the control area. Its performance in the later storage period is particularly of economic value, which significantly increases the overall income. Therefore, the high - calcium and magnesium bio - organic fertilizer can be further expanded for demonstration and promotion.

The agrochemical technicians of the company said that this year, the plan will be further improved based on the organic fertilizer, and a complete set of fertilization models will be designed to gradually promote the high - quality production of grapes.
