Embodiment 1

[0020] In the oligosaccharide-containing foliar fertilizer composition 100g of the present embodiment, the proportions of each component are respectively:

[0021] Sodium alginate oligosaccharide 5g nitrogen 4g phosphorus pentoxide 2g

[0022] Potassium oxide 5g Boron 0.5g Iron 0.2g

[0023] Copper 0.1g Zinc 0.1g Citric acid 4g

[0024] The balance is water

[0025] Put the above materials into a 200ml beaker and stir to fully dissolve various ingredients, mix evenly, and pack separately. When using this product, it should be diluted 1000 times and sprayed on the leaves during the growth period of the crops.

[0026] The oligosaccharide-containing foliar fertilizer of the present invention was tested on field cabbage. The common foliage fertilizer Hailing was used as a control in the market, and there was also a blank control. There were 3 treatments in total, 3 repetitions, and random arrangement. Investigation and statistics were carried out from the plant height, leaf n...

Abstract

The invention discloses an oligosaccharide-containing foliar fertilizer composite which is characterized in that: the composite comprises oligosaccharide with effective treatment quantity and foliar fertilizer with various elements, wherein the content of the oligosaccharide is 1%-5% of the total weight of the composite; the oligosaccharide comprises chitosan oligosaccharide, sodium alginate oligosaccharide and pectin oligosaccharide; the content of the element foliar fertilizer is 5%-50% of the total weight of the composite; and the element foliar fertilizer comprises at least one of nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, boron, ferrum, manganese, copper, zinc and molybdenum. The composite is applied to field crops, commercial crops and fruit and vegetable crops. The oligosaccharide which can induce plants to resist diseases and promote a root system to grow is introduced into the foliar fertilizer, so that the foliar fertilizer composite can promote the growthand the nutrient absorption of plant root systems, and has a certain control effect for restraining the happening of the diseases.

Description

technical field [0001] The invention relates to the field of agriculture, and more specifically relates to an oligosaccharide-containing foliar fertilizer composition and the application of the composition to field crops, economic crops, and fruit and vegetable crops. Background technique [0002] my country is a country with a small area of ​​arable land. To increase the output of grain, oil, cotton and other crops, the output per unit area must be increased. However, the lack of soil and crop elements has become the main factor limiting crop output. Therefore, development Fertilizer production is very important. [0003] With the development of agricultural production and science and technology, since the 1970s, agricultural departments and relevant units of the Chinese Academy of Sciences have successively found symptoms of zinc, boron, iron, and manganese deficiency in soil and crops, which has attracted the attention of relevant departments. Since 1978 in my country, th...
