Abstract

The invention relates to the technical field of peanut culture, and particularly relates to a special growth regulator for peanut seedling stage. The special growth regulator comprises the following raw materials by weight: 2.5-5.0g of Chitosan Oligosaccharide, 50-60g of sea algae extracts, 50-60g of imidacloprid, 50-60g of 50% carbedazim, and 60-100g of saccharose. Through the treatment of the growth regulator, the chlorophyll content and net photosynthetic rate of leaves and root activity of peanut seedlings can be remarkably improved, the improvement amplitude on the dry matter weight of plants, especially dry root weight, is large, therefore, the regulator is beneficial to the growth of seedling roots; the stem rot incidence rate and the quantity of aphids and red spiders in the field investigation show that the regulator can effectively prevent diseases and insect pests, and the quantity of aphids and the disease incidence rate can be remarkably reduced. The regulator is remarkable in yield increase effect since the weight of single fruits is increased, the double-kernel peanut rate and fruit fullness rate are increased, and the shelling percentage is also improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of peanut cultivation, in particular to a special growth regulator for peanut seedling stage. Background technique [0002] The spring peanut seedling stage in Shandong coincides with the migration of aphids and red spiders in the wheat field before the wheat harvest. Severe cases can cause damage to the peanuts. The performance is slow plant growth, yellow leaves, and severe yield reduction. The seedling stage of peanuts is also the initial stage of stem rot. Stem rot causes the plants to wither gradually, is highly contagious, and can also lead to a substantial reduction in yield. At present, the production only pays attention to the prevention and control of pests and diseases in the peanut seedling stage, and lacks the regulation on the growth of seedlings. Contents of the invention [0003] In order to solve the above problem of no growth regulation for peanut seedling stage, the present inventio...
