Problems solved by technology

For loquat trees that have been flooded for a long period of time due to overcast rain or flooded by strong winds, they cannot fully absorb water and nutrients due to damage to the root system. It is even more difficult for such trees to replenish nutrients and water in time with soil application and leaf surface spraying. These damaged trees often appear premature senescence, chlorosis and leaf fall, and even death

Embodiment 1

[0013] Choose old loquats with few leaves and poor branching ability after typhoon waterlogging damage to the root system or damage by diseases and insect pests. Use a 5mm drill bit drilling machine to drill a diameter at an angle of 45 degrees downward on the main pole 30-50 cm away from the upper part of the root neck. 5mm, 4 ~ 5cm deep hole, the size of the hole is basically the same as the diameter of the infusion plug. If the branch diameter of the loquat exceeds 5cm, in order to speed up the absorption of the tree body, 1 to 2 holes of the same diameter can also be punched on the branches of the loquat tree. Then hang the infusion bag containing nutrient solution 1-1.5m away from the infusion hole, empty the air in the infusion tube, and then insert the needle into the punched hole. Adjust the dripping speed to an appropriate amount. Take 1 bag each time the new shoots are pumped, 3 to 4 bags a year. After punching, apply wound protectant to the infusion hole, and then...

Embodiment 2

[0015] Loquat trees are 8 to 10 years old, and nutrients such as calcium, magnesium, molybdenum, boron, and zinc in the soil are lacking, and they need to be supplemented by fertilization. Start the infusion from February to early March one week before spring shoot pumping, and use a 5mm drill bit drilling machine to drill a 5mm in diameter and 4 to 5cm in depth at an angle of 45 degrees downward on the main rod 30 to 50cm from the upper part of the root neck. Holes, the size of which is basically the same as the diameter of the infusion plug. Then hang the infusion bag containing nutrient solution 1-1.5m away from the infusion hole, empty the air in the infusion tube, insert the needle into the punched hole, and adjust the dripping speed to an appropriate amount.

[0016] After punching, apply wound protectant to the infusion hole, and then seal it with a branch. After the infusion, the spring shoots of the loquat tree grow vigorously, the fruit develops well, the single fru...

Abstract

The invention relates to a loquat trace element nutrient solution and a method for using the same. The formula is designed according to the nutrient requirement characteristics of loquat trees, and each liter of water is composed of the following compounds: 2-3g of urea, 2g-3g of potassium dihydrogen phosphate, Calcium nitrate 2-4g, magnesium sulfate 0.5-1.5g, zinc sulfate 1-1.5g, borax 1-1.5g, ammonium molybdate 0.5-1g. The preparation method of the above-mentioned nutrient solution is that after accurately weighing the above-mentioned raw materials, they are completely dissolved in water by stirring, and then dissolved to 1 liter with water. According to the characteristics of the loquat tree, the present invention designs the formula of the nutrient solution, which is rich in trace elements such as calcium, magnesium, molybdenum, boron, zinc and the like needed by the loquat leaves, fruits and flowers, and appropriately supplements the nitrogen, phosphorus and potassium that the loquat tree needs in large quantities. Massive elements. The special nutrient solution for loquat and the nutrient supplement technology through infusion have the advantages of convenient operation, good effect and low cost.

Description

technical field [0001] The invention relates to a loquat trace element nutrient solution and a using method thereof, belonging to the technical field of fruit tree planting. Background technique [0002] Loquat is an evergreen fruit tree native to my country. The fruit is soft, juicy, sweet and sour, and is very popular among consumers. However, due to changes in the way of agricultural fertilizers in my country in recent years, fruit farmers use a large amount of nitrogen, phosphorus and potassium ternary compound fertilizers, while other nutrients cannot be effectively supplemented, resulting in serious deficiency of loquat, affecting yield and quality. This situation occurs because the loquat fruit is rich in phosphorus and calcium, the flowers contain boron and zinc, and the leaves are rich in phosphorus, potassium, calcium, magnesium, and molybdenum. Leaves and flowers fall. If the above-mentioned trace elements are not supplemented, after the original elements in the...
