How to Fertilize Peach Trees for High Yield? Technical Details Explained, Save It Quick
As we all know, all crops need fertilization to grow well, and only when fertilization is done properly can high yield be difficult to avoid. So, is more fertilizer always better? The answer is no. Fertilization does not necessarily need to be excessive, but attention must be paid to technique. Master the rules of fertilization, and apply different fertilizers according to the different growth stages of the plant. The peach tree is a common tree species in daily life, and its growth cannot be separated from fertilizer. Let us take a look below at the key points of high-yield fertilization techniques for peach trees.
I. Benefits of compound fertilizer
Compound fertilizer is suitable as a base fertilizer. It takes effect slowly and requires one to two transformations.
1. Ammonium nitrogen must first be converted from ammonium nitrogen to nitrate nitrogen before it can be absorbed and utilized by crop roots. It is generally alkaline. The lower the temperature, the slower the conversion. When applied in early spring, it needs 15 to 20 days or even more, and as the temperature gradually rises, the conversion speeds up. In summer it needs only about 7 days. Based on its characteristics, it is only suitable as a base fertilizer, with a fertilizer effect lasting more than 90 days.
2. Sulfur-based compound fertilizer generally refers to nitrate nitrogen compound fertilizer, which is an acidic fertilizer. It is absorbed relatively quickly by roots. In early spring when temperatures are low, it needs 7 to 10 days; in summer when temperatures are high, it needs 3 to 5 days to be fully absorbed and utilized by the roots, and then converted through the leaves into organic nutrients to supply plant growth. It can be used as a base fertilizer and also as a topdressing fertilizer, and is relatively suitable for topdressing crops. Its fertilizer effect lasts more than 60 days, and it is not suitable for topdressing and nutrient supplementation at various stages of fruit trees. For example, when topdressing peach trees during the swelling stage, with fruit ripening in about a month, it starts working late; when it should take effect, it does not, and by the time it fully takes effect, the peaches have already ripened, so its effect as a swelling fertilizer is not prominent. This is especially true for early-maturing varieties, which mature early and still have a long later growth period. For example, for peaches ripening in late May and June, the fertilizer still has plenty of power later on, which can only cause excessive vegetative growth of shoots, easily leading to deterioration of light conditions, affecting flower bud formation and quality, and causing a large amount of fertilizer consumption and waste.
II. What types of organic nutrient fertilizers are there?
Mengli 28 and biological enzyme bacteria are organic nutrient fertilizers, meaning they can be directly supplied without processing through leaves for flowering and new shoot growth, making up for insufficient stored nutrient energy and shortening the nutrient conversion period. At each growth stage, combining organic with inorganic (water-soluble fertilizer) can better improve fertilizer utilization, promote robust growth of fruit trees, and the fertilizer effect can reach 25 to 30 days.
III. What are the characteristics of water-soluble fertilizers?
Its characteristics are: it can promote rapid results in crops, timely supply the various elements needed for fruit tree growth at each stage, supplement the insufficient energy of a certain element during a certain period, and achieve maximum fertilizer utilization. The fertilizer effect lasts only more than 20 days. However, it is necessary to understand the characteristics of each water-soluble fertilizer and match them with the fruit growth and development characteristics of the fruit tree in order to maximize the effect. Never fail to topdress what is needed, and never randomly supplement and topdress elements that are not needed.
IV. What fertilizer is good to choose for autumn base fertilization?
In ordinary years, fruit trees and peach trees in the Yuncheng area successively enter the autumn shoot cessation period in late August. Fruit trees enter the third peak of root growth, and peach trees enter the second peak of root growth. If it is a late-maturing variety, it can both supply fruit growth and also enter the stored nutrient stage. Whether the tree vigor is strong and whether flower bud differentiation is good depends on this autumn management (autumn base fertilization and autumn pruning). Base fertilizer is also called bottom fertilizer, so people often say: three topdressings are not as good as one base application, which shows the importance of autumn base fertilization. In terms of fertilizer selection, a formula fertilizer with a relatively long fertilizer effect period and full nutrition must be chosen. To increase soil fertility, more decomposed farmyard manure or organic-matter biological bacterial fertilizer must be applied to improve the soil's granular structure, increase soil aeration, meet the growth conditions of the root system, and promote root growth. This can not only meet the nutrient supply in autumn, but also supply the fertilizer nutrients needed during the fruit tree growth season in the second year.
V. Why topdress water-soluble fertilizer during the growth period?
During the entire growth stage of fruit trees and peach trees, from flowering to the young fruit stage, this period mainly consumes and utilizes stored nutrients, generally for about more than one month. Only after the first large leaf forms in early to mid-May does it enter the stage of utilizing the current year's nutrients, and at the same time, it shifts into the fruit pit-hardening stage. If compound fertilizer is used before flowering, there are no leaves on the tree to synthesize organic nutrients, so it simply cannot be utilized, and the fertilizer effect lasts as long as more than 60 to 90 days. Excessive nitrogen fertilizer is instead not conducive to pit hardening and shoot lignification. Therefore, organic nutrient fertilizer and water-soluble flush fertilizer must be selected, which take effect faster and have better results, are neither wasteful nor unscientific, and are reasonable. By the swelling stage, the three major elements and medium and trace elements change again, so different element fertilizers must be supplied in a timely manner according to the fertilizer requirements of different fruit trees and peach trees at different periods, in order to satisfy the normal and robust growth of fruit trees and peach trees.
