Application method and effect of amino acid micro-fertilizer
2024-06-05 15:09:23
At present, trace elements have an effect of increasing production and income for crops, which has been confirmed by the agricultural science and technology community. However, the absorption of trace elements by plants is severely affected by the antagonism between trace elements and the pH of the soil. In order to ensure the high yield of crops, the utilization of trace elements has become more and more important in recent years. One of the ways to solve this problem is to select suitable chelating agents to sequester trace elements to maximize crops. Its absorption rate. Studies have found that complex amino acids in chelating agents are the best and lowest price. It not only has a moderate stability constant, but is not interfered by soil pH and other ions and can be directly absorbed by crops. Amino acid micro-fertilizer is used in crops and has obvious effects of increasing yield, improving quality, reducing pesticide residues, and protecting the ecological environment. In addition, due to the continuous improvement of the production process of amino acid micro-fertilizers, the source of raw materials is wide (mainly hair, cotton aphid, etc.), the production cost is getting lower and lower, which provides a guarantee for the cheap acquisition of amino acid chelate. Therefore, amino acid micro-fertilizer has played an increasingly important role in agricultural production and plays an increasingly important role.
First, the scope of application
Amino acid micro-fertilizers are used in a wide range of food crops (rice, wheat, corn) to oil crops (canola, soybeans, peanuts), as well as cash crops (cotton, tea, tobacco, mulberry), fruits (apples, pears, Citrus, lychee, longan, peach, plum, apricot, grape), vegetables (cucumber, green vegetables, lentils), etc., have a different degree of promotion for almost all crops.
Second, the use of methods and application effects
Amino acid micro-fertilizer has the effects of increasing yield, improving quality and reducing pesticide residues in crops, and has been confirmed by more and more research institutes at home and abroad. However, the use of different crops is different and the effect is different. The method of use generally has three methods of spraying, seed dressing and foundation application. It is better to spray 300-600 times of liquid, and 1% of seed dressing is better. Compared with the effect of increasing production, spraying is better than seed dressing and base application. The grain is sprayed at the jointing stage, cotton, peanuts and soybeans are sprayed at the initial flowering stage, and the fruit crops are sprayed at the young fruit stage. The dilution is about 50kg per 667 square meters, and the yield increase can reach 10%--50%; The yield increase effect is generally 5% -10%; and the base application can reach 10% - 15%.
Introduce the use and application effects on several major crops.
1. wheat
After applying amino acid micro-fertilizer, it not only has a certain effect on the vegetative growth of wheat, but also can increase the chlorophyll content of the leaves, enhance the photosynthetic capacity, accelerate the grain filling rate, and increase the grain weight and yield. Tests have shown that the combination of seed dressing and foliar application will be better, followed by foliar application, and simple seed dressing has less effect on yield.
2. Chinese cabbage
The transplanted seedlings of cabbage seedlings on the 1st day before transplanting and the planting seedlings at 7d after transplanting and 14d after transplanting were sprayed with different concentrations of amino acid liquid fertilizer respectively, which could increase the plant height, increase the net weight of individual plants and shorten the growth period. .
3. tea tree
Spraying amino acid micro-fertilizer can improve the photosynthesis of tea tree, increase the activity of enzymes in tea tree, promote the growth of new shoots, thick and strong shoots, strong tenderness, increased density of bud heads, increased weight of buds, and increased yield. At the same time, spraying amino acid micro-fertilizer can promote the growth rate of tea tree, and reach the standard of picking tea in advance, so as to pick up the picking period of famous tea. The spraying time was sprayed once during the dormant period of the tea tree, and sprayed once again 26 days before the picking. Spraying should be carried out on a cloudy or sunny afternoon, and both sides of the leaf surface should be sprayed wet.
4. Greenhouse vegetables
According to the test of tomatoes, cucumbers, peppers, leeks and other vegetables in the greenhouse, the amino acid compound micro-fertilizer 300-400 times liquid per 667 square meters is 50kg, sprayed once every 10d after the vegetable seedlings, even sprayed 3 times, all kinds Vegetables increased by 19.0%-35.1% compared with the control, and the quality was improved. In addition, some fungal diseases such as downy mildew, blight, blight and the like can be prevented. Spraying amino acid compound micro-fertilizer can increase the synthesis of anthocyanins and chlorophyll in plants, activate plant functions, promote plant photosynthesis, and enhance plant nitrogen fixation and enhance vegetative growth to increase yield. If seed dressing is used, it can also promote root development and enhance the cold and drought resistance of plants.
5. peanut
Amino acid fertilizer has a good effect on plant growth and root activity, and the number of pods and the number of fruit are also significantly improved. The suitable spraying amount is 80mL/667 square meters each time. It is sprayed once in the seedling stage, the initial flowering and the pod-forming stage, and sprayed 250μg/g of paclobutrazol once every 20 days after the initial flowering to increase the yield of peanuts by 31.1. --34.8kg / 667 square meters, an increase of 12.89% -13.5%.
6. Watermelon
Spraying 300 times of amino acid compound liquid fertilizer in the period of watermelon vine, early flowering and fruiting, respectively, can increase the yield of watermelon by 444.6kg/667 square meters, increasing by 15.8%; the percentage of soluble solids increased by 11%. , an increase of 11.3% over the control.
7. Fruit tree
Spraying amino acid compound fertilizer on the apple tree can increase the venetian weight by 21.0--31.5g, and increase the yield per 667 square meters by 21.6%--30.8%. At the same time, the apple quality can be significantly improved, and the hardness can be increased by 0.02-1.22 kg/cm 2 , the sugar content can be increased by 0.60%--0.84%, and the anthocyanin content is also increased. The concentration of the amino acid compound fertilizer on the apple tree is 500-700 times.
8. cotton
Spraying amino acid compound fertilizer can make cotton seedlings grow stronger and yield increase. The cotton seedlings were sprayed for the first time in the 5--6 leaf stage (about 15 days after transplanting), the second spray from Shenglei to the early flowering stage, and the third time in the flowering and ringing period. Spraying mass concentration and dosage: the first 50--75kg/667 square meters, the second and third times 150kg/667 square meters, the second addition of 1--1.5g/667 square meters of ketamine. Under the premise of no fertilizer damage, the spraying concentration can be appropriately increased, but it is still suitable for 300:1, and can be reduced to 500:1 in the high temperature period or in the greenhouse.
9. Soy
Amino acid micro-fertilizer seed dressing and spraying can significantly promote soybean early maturity, increase crop yield and increase soybean's resistance to stress. Because of the high labor intensity of seed dressing, it can be used together with a seed coating agent. Spraying method can not only increase soybean yield, increase resistance, but also promote early maturity, and the effect is very good.
