The absorption of selenium by jujube trees mainly comes from the soil, which is mainly affected by factors such as plant species, soil available selenium content, and human intervention. The amount of selenium in soil varies from region to region. Selenium exists in various forms in the soil, including elemental selenium, mineral selenium, water-soluble selenium, adsorbed selenium, organic selenium, and volatile selenium. Because selenium has a certain effect on the human body, it is an essential element for plants. To produce selenium-enriched jujube, it is not enough to rely solely on the effective selenium of the soil itself. Therefore, the company launched a special selenium-enriched fertilizer for jujube. This article aims to describe in detail the effects of selenium fertilizer and other selenium fertilizers on jujube trees. effect.
Effects of Different Selenium Fertilizers on the Growth of the Second Branch of Jujube
It can be seen that the secondary branches of jujube trees sprayed with Qiyin activator have significantly greater elongation at the same time than spraying other selenium-containing fertilizers. Among them, the average elongation of the jujube tree by spraying with Qiyin activator is 4.71cm in the same time. , The second branches of jujube trees sprayed with Selenium-enriched Yimiao 198 elongated 1.91cm on average in the same time, and 0.86cm with selenium source fertilizer. The second branches of the jujube sprayed with selenium source fertilizer in the same time The average elongation was 0.46cm, and the secondary branches of the control group with clear water extended 0.34cm in the same time.
It can be seen that the second branches of jujube trees sprayed with Qiyin activator can increase the thickness of the jujube at the same time than other selenium-containing fertilizers. Among them, the average diameter increased by 0.14cm in the same time when the Qiyin activator is sprayed. , The average diameter of the second branches of jujube trees sprayed with selenium-enriched Yimiao 198 increased by 0.07cm in the same time, and the average diameter increased by 0.05cm with selenium source fertilizer. The average diameter of the secondary branches increased by 0.06cm, and the average diameter of the secondary branches increased by 0.05cm in the same time in the control group.
Effects of Different Selenium Fertilizers on the Thickness of Jujube Stem
It can be seen that the average stems of the jujube trees sprayed with the selenium activator increased by 0.09cm in the same time, and the jujube stems sprayed with the selenium-enriched Yimiao 198 increased by 0.08cm in the average diameter at the same time. The selenium source fertilizer increased by 0.09cm on average, and the jujube stems increased by 0.18cm in the same time when sprayed with the selenium source fertilizer. The average stem diameter of the jujube trees in the control group increased by 0.07cm in the same time. In general, these selenium fertilizers have little effect on the thickening of jujube stems, and are at the same level.
Effects of Different Selenium Fertilizers on the Growth of Jujube Trees
It can be seen that the new shoots of jujube trees sprayed with Qiyin activator have significantly greater elongation than other selenium-containing fertilizers at the same time. Among them, the elongation of new shoots increased by 52.7 at the same time when sprayed with Qiyin activator. cm, the new shoots of jujube trees sprayed with selenium-enriched Yimiao 198 elongated an average of 45cm at the same time, and the selenium-rich source fertilizers averaged 41.1cm of new shoots. Sprayed with selenium source fertilizers in the same time Its new shoots elongated an average of 42.7cm, and the control group's new shoots elongated an average of 40.1cm in the same time. Among them, jujube trees sprayed with Qiyin activator had significantly higher shoot elongation than other selenium fertilizers, and were 12.6 cm higher than the control water. It can be seen that Qiyin activator is better than other selenium fertilizers in promoting the elongation of jujube tree shoots.
Effects of different selenium fertilizers on the selenium content and soluble solid content of red jujube
The influence of different selenium fertilizers on the selenium content of red jujube
Spraying different selenium fertilizers has the greatest effect on the selenium content of red dates. The source of selenium is the source of selenium. The selenium content in the red dates treated with selenium source is as high as 0.054mg/kg, followed by selenium source fertilizer, selenium enrichment, and selenium enrichment. The presence of selenium is almost undetectable when treated with Qiyin activator, and so is with clean water. From this point, it can be shown that the internal selenium content of red jujube treated with Qiyin activator is small, and the quality is not as good as the red date processed by its selenium source. It is sufficient to show that the source of selenium has a good effect in increasing the selenium content of red dates and improving the quality of red dates.
Effects of different selenium fertilizers on the soluble solid content of red jujube
The soluble solid content of jujube trees treated with selenium source is higher than that of other selenium fertilizers. The soluble solid content of jujube treated with Qiyin activator is 30.9%, and the soluble solid content of jujube treated with selenium-enriched seconds is 30.9%. The content is 31.6%, the soluble solid content of jujube treated with selenium source fertilizer is 28.9%, the soluble solid content of jujube treated with selenium source is 31.9%, and the soluble solid content of jujube treated with clear water is 27.8 %. It can be seen that the source of selenium has a better effect on improving the soluble solids of jujube.
(Selenium-enriched plant nutrient solution) Detailed introduction of selenium-enriched fertilizer for jujube
Used in jujube and other crops, it can significantly improve plant disease resistance, reduce disease, increase leaf thickness, enhance respiration, enhance photosynthesis, increase dry matter accumulation, increase yield by 10%-20%, and can effectively inhibit arsenic, lead, cadmium, The absorption of mercury and other heavy metals improves the quality. The content of organic selenium in the product is 20-60 micrograms/kg.
How to use: Shake the medicinal solution well before use, dilute it by 500 times (ie 100ml with 50 kg of water), and spray it evenly on the crop leaves. Replenish the spray in case of rain within four hours after application, and do not miss the spray.
Use period: Start to use after the fruit is set, three times in a row, with an interval of seven to ten days, for the fruit that is harvested continuously, spray once for each second harvest.
Packing specification: 100ml*60 bottles/carton
Storage and quality guarantee: Keep away from moisture and light, and the shelf life is one year.
