Powdery-mildew-resistant high-yield nutritive fertilizer for towel gourd

Abstract

The invention discloses powdery-mildew-resistant high-yield nutritive fertilizer for a towel gourd. The nutritive fertilizer is characterized by being prepared from the following components in parts by weight: 20 to 30 parts of urea, 3 to 5 parts of zinc sulfate, 4 to 6 parts of potassium dihydrogen phosphate, 5 to 7 parts of potassium dihydrogen phosphate, 2 to 3 parts of titanium isopropoxide, 3 to 5 parts of traditional Chinese medicinal preparation liquid, 1.2 to 1.5 parts of microelement complex liquid, 1 to 2 parts of sucrose, 0.8 to 1.2 parts of gibberellin, 0.6 to 0.8 part of naphthylacetic acid, 2 to 3 parts of organic acid, 5 to 7 doses of fenaminosulf wettable powder, 0.8 to 1.2 parts of brassin and 2 to 3 parts of attapulgite clay. According to the nutritive fertilizer, besides nitrogen, phosphorus and potassium elements needed by a crop, a microelement is also supplemented; the traditional Chinese medicinal preparation liquid is suitable for crops which are much in water demand, such as the towel gourd, has the functions of fertilizing soil and improving land capability, can be used for improving the disease-resistant property of a cucumber, and can be used for reducing the use of a disease-resistant and bactericidal medicine after being applied; a powdery-mildew-resistant microbial inoculum has a stronger inhibition effect on powdery mildew of the towel gourd, is long in persistent effect, and can be used for effectively preventing and treating the powdery mildew of the towel gourd; the gibberellin and the naphthylacetic acid can be used for obviously improving the germination rate of a seed and the quality of a seedling, improving a fruiting rate and improving the quality of a fruit.

Description

technical field [0001] The invention belongs to the technical field of nutrient solutions, and in particular relates to a high-yield loofah nutrient fertilizer resistant to powdery mildew. Background technique [0002] Loofah is a climbing herbaceous plant of Cucurbitaceae, and the root system of loofah is strong. Stems, five-sided, green, main and side vines grow luxuriantly, stem nodes have branched tendrils, and are prone to adventitious roots. It is distributed and cultivated at home and abroad. In the prior art, the loofah powdery mildew is mainly based on prevention, and sprays 1500 times of 25% Amida suspension concentrate once in the early growth stage, the blooming stage, and the fruit setting stage; 27% high-fat film emulsion 80- 100 times liquid, spray the leaves at the early stage of the disease to form a protective film to prevent diseases. Or when you find sporadic small powder spots on the leaves, you should immediately apply pesticides to prevent and contr...

Problems solved by technology

[0003] At present, there are many kinds of agricultural fertilizers, including various compound fertilizers, etc., since none of them can directly act on the soil for a long time, nor can they be applied throughout the process. Therefore, agricultural fertilizers, cake fertilizers or various organic fertilizers are used as carriers and used as "additives" Supplementary use or "seed dressing" and multiple "foliage spraying" can not provide comprehensive nutrition to crops, and the scope of application is greatly affected by geography, crops, seasons, etc. It is inconvenient to use. At the same time, some agricultural fertilizers contain hormones and toxic substances, which are not conducive to environmental protection and have a great impact on soil quality, which in turn affects the quality and yield of crops.

At present, there are many types of pesticides used for loofah seed treatment in production. Due to long-term use, the loofah bakanae pathogen has developed resistance to carbendazim, and the control effect of these pesticides on loofah powdery mildew has declined significantly.

Moreover, the existing seed treatment agents have incomplete nutrients, narrow bactericidal spectrum, and are not conducive to environmental protection. Therefore, how to apply the excellent characteristics of each agent to carry out compound screening to effectively prevent and control other seed-borne diseases such as loofah powdery mildew, and to be safe to natural enemies , environmentally friendly high-efficiency seed treatment agent is the technical problem to be solved in the present invention
