The country is based on agriculture, farming and planting first. The germplasm resources of crops, also known as varietal resources, genetic resources or genetic resources, are important components of biological resources. They are the material basis for cultivating high-quality and high-yield crops, are an important guarantee for maintaining national food security, and are important for the sustainable development of China's agriculture. basis. Seeds are important agricultural means of production and are directly related to the safety and social stability of agricultural production.
In order to effectively maintain fair competition in the market order, promote the healthy development of the seed industry, ensure the safety of seed production for agriculture, and conduct annual inspections of seed resources for production and operation of seed traders, and carry out three indicators of seed cleanliness, moisture, and germination rate. Testing. The Crop Germplasm Bank is an instrument developed to study the impact of the storage environment on the lifespan of seeds. The TPZY cold seed standard sample adopts a dual temperature dual standby system, which can use the germplasm for 3-30 years.
The following issues should be noted in spot checks on crop germplasm resources:
1. To determine the focus of spot checks, the unqualified production and operation enterprises that have conducted inspections of seed quality in the previous year should be the focus of spot checks in the same year.
2. Newly-established seed companies check the legitimacy of their operating varieties, and whether the labeling content of the seed tag is authentic, legal, complete, and normative. Whether the company has the ability to independently assume risks, storage and maintenance facilities (for example, seed banks that can be used for seed storage) and instruments that test the quality of seeds are compatible with the basic conditions for the types and quantities of seed they operate.
3. During the process of crop seed inspection and operation, it is necessary to ensure that the quality of the seeds of the sample taken is representative, and it can represent the quality of the batch of seeds and cannot be subjectively extracted.
4. There may be heterogeneity in the seed lot that needs to be inspected, and in that case it will not be representative even if it is sampled strictly in accordance with inspection procedures. If there is heterogeneity, sampling should be rejected.
Ceramic Filter plate has following characteristics: large filter area, high intensity and even aperture. Besides, the aperture size can be adjusted according to actual demands. The basic material is alumina, it has good resistance to acid and alkali. After a period of application, the ceramic filter board can be cleaned by cycle reverse cleaning, ultrasonic and chemical cleaning agent and so on, to let the boards work with high efficiency.
