Description

Composite organic fertilizer, preparation method thereof, soil repairing agent and application thereof and planting method of plant

Technical field

The invention relates to a preparation method of a composite organic fertilizer, a composite organic fertilizer prepared by the method, a soil repairing agent containing the above composite organic fertilizer, and the application of the soil repairing agent in soil remediation, and a plant Planting method.

Background technique

At present, China's agricultural land is extensively degraded, compacted and heavily metallized. Soil degradation, compaction and heavy metallization are the result of a more evolutionary use of fertilizer.

The earliest used organic fertilizer. The use of organic fertilizer has a long history in China. Farmers have a proverb: a crop of flowers, all relying on feces. The most important part of farming is the accumulation of fertilizer. For thousands of years, farmers have basically relied on soil and fertilizer to cultivate. Nowadays, organic fertilizers in the market are generally divided into three categories: farmyard manure, green manure and humic acid fertilizer. The characteristics are: many nutrients, low concentration, slow release, but only Make base fertilizer.

Followed by fertilizer (also known as inorganic fertilizer). After the end of the Second World War, in order to adapt to the rapid growth of the world population, the application of chemical fertilizers has become a powerful measure to increase agricultural production. China began to use it on a large scale in 1963. Fertilizers are generally classified into nitrogen fertilizers, phosphate fertilizers, potash fertilizers, compound fertilizers, compound fertilizers and trace element fertilizers according to their active ingredients. Its characteristics are: high concentration and fast release.

In addition, it is microbial fertilizer. The Ministry of Agriculture began to include microbial fertilizer in the fertilizer registration category in 1996. It is stipulated that microbial fertilizer must be inspected and registered in the Ministry of Agriculture. It is a bacterial fertilizer, a living organism, and a powerful decomposition and reduction by bacteria. Activities play a role. China's microbial fertilizer research has been carried out for more than 10 years, and many experiments have been done, and good results have been achieved. One of the experimental data, namely, Ziyunying, shows that the first year after the application of microbial fertilizer, the yield will increase by 60%-100%; the second year will increase the yield by 20%-60%; the third year will increase the yield by 15%-40%; the fourth year will increase the yield. 10%. Microbial fertilizer types can be generally divided into: microbial seed dressing agents, various rhizobial fertilizers; compound microbial fertilizers; among them, compound microbial fertilizers contain bacterial fertilizers (rhizobial fertilizer, nitrogen fixation, phosphorus dissolving, potassium dissolving), actinomycetes ( Antibiotics), fungal fertilizers (mycorrhizal fungi, mold fertilizers, yeast fertilizers) and photosynthetic bacteria fertilizers. It is characterized by initial use, robust crops, and high yields.

However, the long-term application of the above three fertilizers has a major impact on soil degradation, compaction and heavy metallization. First of all, in recent years, people have used various feed additives and various antibiotics in the feed for animal breeding. Caused the insecurity of animal droppings. The field crops use organic fertilizer as the base fertilizer. As a result, the soil is seriously polluted and degraded, posing a threat to people's health. Secondly, due to the single nutrient nutrient, after use, the soil nutrient ratio is imbalanced; the farmland ecological environment is destroyed; the soil physical and chemical properties are seriously deteriorated. The most striking effects of chemical fertilizers on agricultural products are vegetables and fruits. The main manifestations are: the formation of nitrates after the crops have absorbed nitrogen fertilizer, and further conversion into nitrite. High amounts of nitrite are the main culprit in cancer. In addition, as agricultural workers over-exploit fertilizers in the soil in recent years, the result is severe soil contamination, compaction and degradation. Third, microbial compound fertilizer is also called whole fertilizer. The effect of microbial compound fertilizer in the past few years is particularly good, because it is an active alien species, which will destroy or even destroy the original species of the land. However, after three to five years, the land gradually Not long crops, resulting in the loss of land effectiveness.

Therefore, in the face of the large-scale performance degradation, slab formation and heavy metallization of agricultural land in China, there is an urgent need for a repairing agent capable of repairing existing degraded soil.

Two plots were selected on the Huashan desert in Zibo, Shandong. On one of the plots, 300 kg of soil remediation agent prepared in Example 1 was applied per acre, and the other did not apply soil remediation agent, but an equal amount of inorganic fertilizer was applied, and then the millet was planted. The state of growth of the millet was recorded, and the state of the millet in the harvest season on the soil to which the soil conditioner was applied was as shown in FIG.

As can be seen from the comparison of Figures 1 and 2, the rice to which the composite organic fertilizer of the present invention is applied is thicker and the root system is more developed than the seedling of the rice to which the inorganic fertilizer is applied. In addition, the rice to which the composite organic fertilizer of the present invention is applied has higher yield, lower heavy metal content, and the heavy metal residue of rice is as low as almost zero. Therefore, the rice planted by the composite organic fertilizer of the present invention is compounded by the national green standard.

As can be seen from the comparison of Figures 3 and 4, the camellia to which the soil remediation agent of the present invention is applied grows faster, the leaves are more full, and the yield is higher than that of the application of the inorganic fertilizer, especially the yield before the clearing can be increased by three times.

It can be seen from the comparison of Figures 5 and 6 that the tree height, the DBH and the volume of the eucalyptus planted by the soil remediation agent are significantly higher than the conventional fertilization, indicating that the soil remediation agent of the present invention can promote the rapid growth of trees.

It can be seen from the data in Table 1 that the content of selenium in edible chrysanthemums and carrots planted after application of soil remediation agent is higher than that of edible chrysanthemums and carrots grown in soil without using remediation agents, indicating that soil remediation agents can improve the quality of fruits. .

As can be seen from the comparison of Figures 7 and 8, the radish harvested on the soil after application of the soil remediation agent has a larger head, wherein the larger radish has a body length of 46 cm, a diameter of 15 cm, a weight of 5.2 kg, and the harvested radish tastes extremely Ok, returning to the natural taste, the yield is also high.

It can be seen from the comparison of Figures 9 and 10 that the application of the soil remediation agent increases the ground temperature by 2-4 ° C, and the growth is unaffected, and the yield is greatly increased. Therefore, in the low temperature condition, the strawberry in the greenhouse is obviously applied with the soil repair agent. It is more resistant to freezing than greenhouse strawberries that do not use soil remediation agents. Therefore, the soil remediation agent of the present invention can significantly improve the cold resistance of plants.

It can be seen from the comparison of Figures 11 and 12 that under drought conditions, the pepper applied with the soil remediation agent is significantly more drought-resistant than the pepper without the soil remediation agent, thus indicating that the soil remediation agent of the present invention can significantly improve the drought resistance of the plant. .

As can be seen from the results of Test Example 8, on the soil to which the soil remediation agent was not applied, since the soil layer was only 2-3 cm, and the soil layer was sand rock, the millet could not be grown at all. On the soil to which the soil repairing agent of the present invention is applied, the grain of the millet is large and the yield is high, which proves that the soil repairing agent of the present invention can transform the sandy soil, which is unique in the world.
