Maize seed storage management technology

The storage environment of corn seeds directly affects the vitality of the seeds. To ensure its safe storage, scientific management methods must be adopted.

Clean up and disinfect the seed warehouse. Before the seeds are put into storage, the warehouses and the warehouses must be cleaned and disinfected. For sacks, woven bags, sieves and other appliances, scraping, knocking, punching, washing, insolation, and hot water boiling can be used for cleaning. All kinds of seeds, impurities and garbage in the warehouse should be removed. Scratch the wormhole and repair the wall surface. At the same time, clean up outside the warehouse. The warehouse can be sprayed with 80% dichlorvos emulsifiable concentrate 100-200mg/m 2 by spraying or hanging bar, and then sealed for 72h. After disinfection, it must be ventilated for 24 hours before entering the warehouse. Can also be used 0.5% -1% solution of trichlorfon evenly sprayed, spraying 3kg liquid per 100 square meters.

Put good seeds into storage. When seeds are in storage, the seed quality, seed maturity, and crushed grain rate should meet the required standards. At the same time, the seed moisture content must not exceed 13%. To achieve "five divisions", that is, seeds of different levels should be separated; dry and wet seeds should be separated; seeds that are moist and free from moisture should be separated; new seeds should be separated; Chen seeds should be separated; separate.

Strengthen warehouse ventilation. When the temperature in the warehouse is high, or when the moisture content of the seeds is large, ventilation must be performed in time. The seed ventilation time should be between 9:00-10:00 or 18:00-19:00. Do not ventilate at noon. Ventilation must master four essentials, namely, clear pass, closed rain, and impassable snow; dripping into ice can pass through; early pass, late pass, and noon pass; nighttime fog can not pass.

Diligent in seed inspection.

Check the temperature. Pay attention to checking the seed temperature in time according to the seed moisture content. The check should be sunny, from 9:00 am to 10:00 am. The bulk warehouses are sampled on the upper, middle, and lower 3 floors. Each floor is inspected at 5 points for a total of 15 places. The inspection of bagged piled-up seeds should also be fixed and fixed, and can be divided into upper, middle, and lower levels.

Second check the moisture. With 25 square meters as a test area, a total of 15 sampling methods using 3 layers and 5 points were used. The interval between inspections is checked once a month in the first and fourth quarters, and in the second and third quarters.

Three check the germination rate. Seeds that are stored for a short period of time are generally not checked for germination, and seeds stored for a long period of time should be checked for germination once every 4 months. In addition, according to the changes in temperature and before and after the fumigation should also be checked. The last inspection should be conducted 10 days before delivery.
