Grape yield increase sweetening technology

Summer is the season when grapes are abundant. If you can eat a crystal of sweet, sour grapes, the mood will certainly be sweet. The taste and color of the grapes determine the value of the grapes. However, due to the excessive application of large amounts of chemical fertilizers to the soil and unreasonable management, problems such as acidification and compaction of the soil are caused, which directly affect the yield and quality of the grapes, resulting in unsweetened and sour grapes and poor texture. , low yield and other phenomena. The output of grapes and the quality of the grapes directly affect the income of farmers. Therefore, reasonable fertilization and field management during the grape growing season is a key step in the high yield and quality of grapes.

First, pay attention to the basic fertilizer

Around October, the end of autumn, is the best time for grapes to use base fertilizer. The application of base fertilizer should pay attention to the application of organic fertilizer and microbial fertilizer, per acre application of rotted organic fertilizer 4,000 kg to 5,000 kg, Jinbao microbial fertilizer 2 to 3 kg; not to ignore chemical fertilizers (mainly nitrogen, phosphate fertilizer) With the cooperation, 15 to 20 kg of urea or 30 to 40 kg of ammonium sulfate is applied per acre. The base fertilizer is buried deep into the ground in combination with the soil. This mode of fertilizing organic fertilizer plus microbial fertilizer and chemical fertilizer not only provides quick nutrition to the grapes, but also improves the micro ecological environment of the soil and plays a role in improving the soil. The reason: The beneficial microorganisms in the microbial fertilizer of the golden treasure activate the soil through the secondary metabolites produced by its own life activities, which increases the amount of soil granules, fertilizes the soil, and increases the absorption rate of the grape roots. Make preparations for the flowering results of the grapes.

Second, timely and reasonable fertilizer

1. Before germination: In early spring buds begin to expand. At this time, quick-acting nitrogen fertilizers should be used, supplemented by microbial fertilizers, and the top dressing is better. The amount of application accounts for about 10% to 15% of the annual fertilization amount. This dressing will promote the absorption of roots after the grape enters the wound period. The application of the golden baby bacteria fertilizer can also increase the germination rate, increase the inflorescence, and make the new shoots grow robustly, thereby increasing the yield. If the amount of autumn fertilizer is sufficient, you can not top-dress this period.

2. Dressing before flowering: spraying fertilizers out of the roots two weeks before flowering, this time mainly spraying boron fertilizer, and can also be used for spraying golden baby microbial sweeteners. This sweetener not only plays a role in flower protection and fruit protection, but also improves the transformation of photosynthetic substances. It has a good effect on flowering, pollination, fertilization and fruit set and flower bud differentiation in the year. For Kyoho, drunk gold incense, Yushang 4 and other fresh foods that are easy to fall and fall, they have a very good fruit preservation effect.

3. Top-dressing during young fruit: After Xiehua, the top dressing of young fruit is mainly applied with nitrogen fertilizer, and phosphorus and potassium fertilizers are used in combination. In combination with deep-sloped land, the fertilizer is buried 30 to 50 cm away from the plant, and is 15 to 20 cm deep in the shallow ditch or hole. In addition, spray the Golden Delicious sweetener once. This topdressing not only promotes the expansion of young fruit, but also is very important for the bud differentiation of shoots and axils. The application of sweeteners can promote grape coloring in advance and accumulation of sugar.

4. Berry ripening fertilizer: spraying microbial sweeteners, when the fruit begins to color, apply a lot of potassium, calcium-based golden treasure sweetener. In this period, fertilized gardens should not use nitrogen fertilizer. Fertilization method using root application, leaf spray can be. The golden treasure microbial sweeteners have an important effect on increasing the sugar content of berries, improving the fruit quality and promoting the growth of new shoots; they can increase the sugar content by 0.8 to 1.5, and can be colored in advance to prolong the storage period.

Third, the field of attention to the problem

In addition to reasonable base fertilizer and timely fertilizer, some aspects of field operations can not be ignored.

1. Basal fertilizer must be decomposed after application, especially chicken manure. It is best to use the Kinpo Fertilizer Fermentation Agent to ferment and then apply it to the ground. Basal fertilizer can not always be applied in one place, and it is easy to cause the growth of roots to be blocked and rot to die.

2. When trying top-dressing, you should try to avoid hurting the rough roots. After fertilization, it must be poured once. According to the fertilizer content of the soil in the garden, the elements that are lacking can be added, especially some trace elements.

In addition, we must cooperate with reasonable pruning and field weed removal.

Reasonable fertilization is the key to glucose production and sweetening, and the application of organic fertilizer and golden treasure microbial fertilizer increases the inhalable trace elements in the soil and various organic acids secreted by microorganisms, which increase the accumulation of glucose and The main factor of bright colors. In addition, the use of the golden sweet baby microbial sweetener does not produce any side effects, allowing the grapes to sweeten under natural conditions, achieving the health and environmental protection requirements.
