Key points of garden management techniques for grapefruit trees
Grapefruit is one of the common fruits in daily life. It has unique flavor and rich nutrition. It is favored by consumers and has high planting value. In the process of planting grapefruit trees, the management of gardens can be said to be the key to stable and high yield of grapefruit trees.
First, deep cultivation and expansion
In principle, in the few years before the pomelo tree is put into production, it is very beneficial to turn over the whole garden. When the soil layer is pressed into the green manure by deep tumbling, it will improve the structure and physical properties, and lay a good soil environment for the growth and development of the pomelo tree. At the same time, in the 3 to 4 years after planting to the time of production, the planting points will be expanded year by year to meet the expansion and growth of the root system, and promote the growth of the canopy crown to meet the requirements of high yield and high yield.
Second, cultivating and weeding
The cultivating can loosen the topsoil, reduce the evaporation of water in the garden, and facilitate the infiltration of rainwater into the garden soil. It can not only improve the ventilation condition of the garden soil, but also improve the fertility of the garden soil and facilitate the development of the root group. At the same time, cultivating combined with weeding can also prevent pests.
Third, the soil in the teak
The soil has improved soil and prevented the roots of the teak from being exposed. The soil can be used for pond mud, river mud and mountain soil. The benefits of soil conservation play a role in preventing drought, moisturizing, cold and warmth.
4. Fertilization of teak trees
1. Fertilization of juvenile trees: time of application. After the planting is alive, it is necessary to apply the manure and excrement in a timely manner, and add 3 kg of decomposed manure per 50 kg of water, once a month, and the amount of fertilizer applied per plant should be appropriate. gradually increase. At the same time, in the first half of the young shoots of the young pomelo tree, high-quality water and fertilizer should be applied. Each plant is given 5 kg of decomposed manure and urea plus 50 g of urea to promote the shoots. This will ensure that each new new hair will grow and grow stronger and stronger, so that the young tree will form a high-yielding canopy at an early date.
2. The result of tree fertilization: First, the application of flower fertilizer. Apply before and after the beginning of spring, each plant is applied with 35 kg of simmered pigs and 50 kg of manure water, applied in strips, and covered with soil after fertilization. The second is to apply fruit and fruit fertilizer. It is applied before and after the Qingming period and before the autumn. Before and after the Qingming, 1 kg of compound fertilizer was applied per plant, and at the same time, manure water was applied again in late April. 250 kg of urea was added to each plant for 25 kg; 1% urea was applied per plant before the beginning of autumn. The liquid can be 50 kg. The third is fertilization after fruit picking. Under the application of Lidong, this fertilization is combined with the deep green pressure in winter. Each plant is given 50 kg of manure water with 1.2 kg of peanut bran, 500 g of phosphate fertilizer and 0.5 kg of urea.
5. Irrigation and drainage of grapefruit gardens
The teak tree is an annual evergreen fruit tree. The leaves are large and fruity. There are many requirements for water. When it is drought and water shortage, it is necessary to irrigate. If it encounters heavy rain and heavy rain, it should be drained in time to ensure the healthy growth of the tea tree. Conducive to teak flowering results.
Six, crown trim
1. Juvenile tree: re-formed at an early age. When the height of the plant is as long as 0.4 m, the top of the tree should be cut, leaving 3 to 4 pieces of the main branch of the distribution, and in the second year, the side branches are cultivated on each main branch to make the teak. Form a rounded, high-yielding canopy.
2. Result tree: It should be properly pruned to achieve the tree-shaped ventilation, light and leafy, and stable and high yield every year. Pruning takes place in winter and summer. Summer shear: It is a delicate branch that has been cut too densely, a short cut and a long branch, and a large branch that is too shaded at the center of the top of the crown, so that the light penetrates into the canopy of the canopy, thereby promoting the result that the mother branches are enriched to form flower buds and facilitate fruit growth and development. Winter Shear: After picking the fruit, cut off the dead branches, the diseased branches, and the decaying branches.
Doing a good job in the management of the grapefruit tree field is of great significance to improving the yield and quality of the grapefruit tree planting.

Amino acids are organic compounds containing basic amino groups and acidic carboxyl groups. A compound formed when the hydrogen atom on the carbon atom of a carboxylic acid is replaced by an amino group.Amino acids contain two functional groups: amino and carboxyl groups. Similar to hydroxy acids, amino acids can be divided into α-, β-, γ-, W -... Amino acids, but all of the amino acids you get from proteolysis are alpha-amino acids, and there are only 22 of them, Including glycine, alanine, valine, leucine, isoleucine, methionine, methionine, proline, tryptophan, serine and tyrosine, cysteine, phenylalanine, asparagine, glutamine, threonine, aspartic acid, glutamic acid, lysine, arginine and histidine, selenium cysteine and pyrrole lysine (found only in a few bacteria), which are the building blocks of proteins.Basically, amino acids exist as facultative ions or dipolar ions in aqueous solution or crystal. The so-called zwitterion refers to the same amino acid molecule with NH3+ valine ions, which can release protons, and COO- ions, which can accept protons. Therefore, amino acids are amphoteric electrolytes.we have Organic Curcuma Longa powder,apple flavor powder,TBHQ,sodium alginate,Allura red,carmine cochineal,Organic Chlorella Vulgaris,Citric acid.
