What causes fruit not sweet?
Date:2024/08/01
Poor fruit coloring, lack of sweetness, poor taste, these problems not only make fruit farmers headache, but also directly lead to significant economic losses. Did bagging make the fruit lose the sun's flavor? Or does the sugar water injection mistake make the whole tree sweet?
So, what is the reason why the fruit is not sweet? And how to manage to make the fruit sweet?
Reason one: the soil
Older orchards, basically more than 3 years old orchards, due to large areas of planting fruit trees, and fruit trees need more fertilizer, due to rough fertilization, improper soil management, the use of herbicides and other reasons, resulting in soil nutrition imbalance, soil compaction and a series of soil problems.
The soil environment is not good, the fruit tree root growth is poor, the absorption of nutrients is blocked, and the fruit produced by the fruit tree naturally tastes poor.
To improve soil problems, the most important measure is to apply fertilizer, less herbicides, more organic fertilizer, biological fertilizer, the use of organic fertilizer rich organic matter, nutrient elements, beneficial bacteria in biological fertilizer, fully adjust the soil structure, pH value, improve physical and chemical properties, and restore soil nutrient balance. At this time, the fertilizer produced by the Organic Fertilizer Production Line becomes an important source of nutrition. By increasing the application of organic fertilizer, the organic matter and nutrient elements in the soil can be enriched, the soil structure can be improved, and the comprehensive nutritional support for fruit trees can be provided.
Reason two: farm fertilizer
Long-term use of single chemical fertilizer is an important reason for the poor taste of fruits. Chemical fertilizer has a single nutrient element and fast fertilizer effect, which can not meet the nutritional needs of fruit trees during the growth cycle.
Nitrogen fertilizer can promote reproductive growth, but excessive will make fruit color late, color deterioration; Potassium fertilizer can promote the fruit to increase and sweetening, but excess will also increase the acidity of the fruit.
Farm fertilizer is also a common fertilizer used in orchards, but farm fertilizer has a big disadvantage, undecomposed farm fertilizer diseases and pests, and the use of a large number of farm fertilizer will cause root burning phenomenon.
Therefore, orchard fertilization, can not apply a single fertilizer, can not apply undecomposed farm fertilizer. It is recommended to use refined organic fertilizer, with biological fertilizer can not be less, play the advantages of the combination of organic and inorganic - long-term and short effect, can meet the characteristics of fruit trees need large fertilizer, need long fertilizer cycle.
In the process of fertilization in orchards, the form and grain size of fertilizer have an important effect on fertilizer efficiency. At this time, the Rotary Drum Granulator and the Disc Granulaor play a key role.
Rotary Drum Granulator: It uses the principle of rolling friction and extrusion to roll the wet fertilizer raw materials into ball particles in the roller. The Rotary Drum Granulator has the advantages of large yield, uniform particle and high density, which is very suitable for the fertilizer production needs of large-scale orchards. The fertilizer particles produced by the Rotary Drum Granulator are not only easy to store and transport, but also can improve the utilization rate of fertilizer to ensure that the fruit trees get accurate nutrition supply.
Disc Granulaor: Unlike the Rotary Drum Granulator, the Disc Granulaor uses centrifugal force to sprinkle fertilizer raw materials on a rapidly rotating disc, forming particles through the collision and extrusion of particles. The Disc Granulaor is suitable for granulating a variety of materials, especially those with large viscosity. In orchards, it can be used to produce specific types of organic fertilizer or composite fertilizer pellets to meet the needs of different stages of fruit tree growth.
In addition, trace element fertilizer can not be less, such as boron calcium fertilizer, can obviously improve the sweetness of the fruit.
In addition, light and temperature, which are also very important factors affecting the sweetness and color of the fruit. Therefore, the management of the orchard is really sloppy, must be diligent management, so as to ensure that the fruits are good and taste good.
Reason three: Herbicides
To remove orchard weeds, some fruit farmers recommend the use of weeding machinery, but when using weeding machinery, be careful not to hurt the root system of the fruit tree.
In addition to the use of weeding machinery, straw can also be used. Piling stalks on weeds and slowly decomposing stalks can not only control weeds, but also provide rich organic matter for soil and fruit trees and improve soil properties.
In addition, less use of chemical pesticides to kill orchard pests, more use of biological control.
Reason four: Bagging
Fruit bagging, the main function is to prevent the pollution of the fruit when spraying pesticides, but also to prevent birds from pecking, so that the fruit looks good.
Bagging techniques should be used correctly:
1. Bagging should be carried out on sunny days;
2. Remove the excess leaves on the stalk or ear base before bagging;
3. Before bagging, the fruit trees should be disinfected and sterilized;
4, bagging time should not be too early, the banana should be bagged 15-20 days after the bud is broken; Longan litchi after the end of fruit thinning; Pears and peaches are bagged about 30 days after the flowers fall; Mangoes are harvested 45-60 days before harvest; Loquat is bagged after thinning and fixing fruit about 30 days after the flowers fall. Pomelo and mandarin were bagged from mid-May to early June.
In order to make the bagged fruit taste good, some time before picking (generally 10-20 days) to pick the bag, so that the fruit is exposed to light. Therefore, bagging can not be picked too early or too late.
