Problems solved by technology

Fertilization at the seedling stage is based on experience. Blind and unreasonable fertilization will cause nutritional imbalance and deficiency of lotus root; coupled with long-term flooding and unreasonable fertilization, hydrogen sulfide and other reducing toxic substances will poison the root system, and the growth of lotus root will be poor. cause serious damage
[0008] At present, there are no good comprehensive preventive solutions for the above-mentioned situations.

Embodiment 1

[0046] According to the above material selection requirements, prepare corresponding composition materials, weigh the ingredients according to the physical components in Table 1, and produce according to the above production process to obtain the lotus root field duckweed control multi-effect nutritional composition of this embodiment;

[0047] Table 1

[0048]

[0049] The product of the composition of this example was used in the lotus root field of Li Wenbi's house in Yongxin Town, Santai County, Sichuan Province, and a comparison experiment was carried out in two fields with conventional fertilization of urea for raising seedlings. On April 17, 2013 (13 days after planting, when the lotus root buds just came out of the ground and did not emerge from the water), 5 kg of this composition was evenly sprinkled on the lotus root field per mu, and 5 kg of urea was evenly sprinkled on the lotus root field in the other field, and both kept 5-7 cm deep and shallow water layer, n...

Embodiment 2

[0053] According to the above material selection requirements, prepare corresponding composition materials, weigh the ingredients according to the physical components in Table 2, and produce the lotus root field duckweed control multi-effect nutritional composition of this embodiment according to the above production process;

[0054] Table 2

[0055]

[0056] The composition product of this embodiment was compared with conventional fertilization of urea in the lotus root field contracted by Huang Shenghai, Longsheng Township, Daying County, Sichuan Province, for seedling raising. On April 26, 2015, 5 kg of this composition was evenly sprinkled on the lotus root field per mu, and 5 kg of urea was evenly sprinkled on the lotus root field in the other field, and both kept a 5-7 cm deep and shallow water layer, without irrigation or drainage for 7 days .

[0057]After 36 days of use, three-point survey was taken (on May 31): with the lotus root combined by the present inventi...

Embodiment 3

[0060] According to the above material selection requirements, prepare corresponding composition materials, weigh the ingredients according to the physical components in Table 3, and produce according to the above production process to obtain the lotus root field duckweed control multi-effect nutritional composition of this embodiment;

[0061] table 3

[0062]

[0063] The composition product of this example was planted in the lotus root field contracted by the family of Hu Shengyong, a large family in Tongliang County, Chongqing City, and compared with conventional fertilization of urea for raising seedlings. On April 19, 2015, when the first money leaves of some lotus root plants came out of the water, 5 kg of this composition was evenly sprinkled on the lotus root field per mu, and 5 kg of urea was evenly sprinkled on the lotus root field in the other field, and both kept 5-7 cm deep and shallow water layer, no irrigation or drainage for 7 days.

[0064] 39 days (May 2...

Abstract

The invention discloses a multi-effect nutritional composition for controlling a lotus root field duckweed. The multi-effect nutritional composition is prepared from, by weight, 30-50% of nitrogen fertilizer, 10-25% of phosphate fertilizer, 12-20% of potash fertilizer, 1.5-2.0% of zinc sulfate, 3.0-8.0% of copper sulfate, 5.0-10.0% of sodium silicate, 0.3-0.8% of isopropylamine and 0.8-1.5% of triphenyltin chloride, 2.0-4.0% of acorus gramineus extract, 1.0-2.5% of tetramycin and the balance peat. The multi-effect nutritional composition is prepared by scientifically combining several efficient inorganic fertilizers, pesticides, plant-sourced extracts and the like according to the agricultural demands for production at a lotus root seedling stage, can meet the reasonable nutrition requirement at the lotus root seedling stage, can also prevent and kill the lotus root field duckweed, spirogyra, eleocharis yokoscensis, water dropwort, crab grass and other weeds, improves the resistance, relieves the harm of toxic substances to lotus root systems and prevents lotus root rot diseases and ampullaria gigas, the pesticide applying amount is decreased by controlling unreasonable fertilization, and high-yield and high-quality lotus root production is achieved.

Description

technical field [0001] The invention relates to a crop nutritional composition, in particular to a multi-effect nutritional composition for controlling duckweed in lotus root fields. Background technique [0002] Lotus root (Nelumbo nucifera Gaertn) is a widely cultivated aquatic vegetable in my country. It is deeply loved by the people because of its rich nutrition and excellent health care effects. [0003] Duckweed (Lemna minor), also known as duckweed grass, water duckweed, and waterweed grass, is a floating plant on the water surface of the family Duckweed. Algae, Spirogyra, Spirogyra. They are all malignant weeds that are hard to get rid of in lotus root fields. On the one hand, they often compete with lotus roots for nutrients, which increases the amount of fertilization and costs; At the same time, it competes for and consumes oxygen, causing the roots of the lotus root to produce hydrogen sulfide and methane poisoning due to poor gas exchange, causing the roots to...
