Rotting disease prevention new technology for peanut root rotting stem

Abstract

A rotting disease prevention new technology for a peanut rot rotting stem is characterized by comprising technologies of crop rotation, seed management, seed processing before broadcasting, deep tillage and soil overturning, cultivation management with fertilizer and water as the center and chemical control. By the use of the new technology, disease spreading and propagation path for soil with bacteria, seeds with bacteria and manure with bacteria can be prevented, so peanut growth potential can be improved and disease resistance capacity can be enhanced; and the new technology is suitable for prevention of rotting disease for peanut root rotting stem.

Description

technical field

[0001] The invention relates to the field of peanut planting, in particular to a new technology for the prevention and treatment of peanut root rot and stem rot. Background technique

[0002] At present, due to the continuous planting of peanuts, soil-borne diseases such as peanut root rot and stem rot have become common diseases, which are very common and serious hazards, especially in heavy-cropping plots, which have increased year by year, seriously affecting the yield and quality of peanuts. Its harmful symptoms are as follows:

[0003] 1. Peanut root rot. Commonly known as "rat tail", it can occur in all growth stages. Peanuts are infected after sowing and before emergence, infecting the newly germinated seeds, resulting in rotten seeds without seedlings; if the seedlings are damaged, the main root will turn brown, and the plant will wither; if the adult plant is damaged, there will be sunken long strips of brown lesions on the main root rhizome, and t...

Examples

Embodiment Construction

[0014] 1. Implement crop rotation. Fields with mild diseases are rotated every other year, and fields with severe diseases are rotated for 3 to 5 years. Rotate with gramineous crops such as wheat and corn, and avoid interplanting and interplanting with soybeans and sweet potatoes.

[0015] 2. Collect and manage the seeds well. Peanuts used as seeds should be harvested in time, dried in the sun, and stored in a ventilated and dry place, protected from moisture and mildew.

[0016] 3. Seed treatment before sowing. Select disease-free seeds before sowing, dry the seeds, and carry out seed treatment at the same time. You can use 50% carbendazim wettable powder with 0.3-0.5% of the seed weight for seed dressing or use 2.5% Shileshi seed coating agent at a ratio of 1:500 (drug : species) for coating.

[0017] 4. Deep plowing to improve the soil. After the peanuts are harvested, the land shall be plowed deep in time to eliminate some overwintering pathogens, and the ground shall...
