artificial lawn quality identification and recognition

artificial lawn quality identification and recognition

Grass seed quality is one of the key factors for grass cultivation, its quality has a direct impact on the success of grass planting.

        Quality grass seed is not only to ensure that all seedlings planted pasture, Miao Zhuang, but also to ensure the yield and quality of forage; poor quality grass seed growers not only cause duplication of efforts, and make growers suffered economic losses or, worse, will cause growers inch of grass do not charge. The pros and cons of the grass seed quality is generally from eight aspects judgment: true, pure, clean, full, strong, strong health, to achieve these requirements through the following methods to ensure and determine:

       A field test

       Seed production, rather than seed production in seed production fields in accordance with the requirements of the harvest of the seeds can not be used as seeds, especially hybrids or strains because of its Genetic Performance unstable offspring will produce separation, harvested from non-farming system hybrids seeds continue to make use of it will lead to great inconsistencies and grass yield decline in production traits. In seed fields produce seeds, but also by the seed requirements of the various conditions, such as the Liumiao the number of trees, spacing settings, Ruomiao rejuvenation, reasonable fertilization and irrigation, the establishment of the buffer zone, buffer zone, etc.. When grass seed Tianfa Sheng more serious diseases, pests or weeds mixed with more, it is necessary to cut off the grass mow, rather than to be reserved for the closing species. Tanaka received seed on seed plants to be checked on a regular basis, observe the growth of plants and seed development, when the seed is full of mature harvest in a timely manner, and in accordance with the requirements of seed processing threshing, Shaizhi storage, after some sleep further period of market supply or sale. Buy seeds, seeds Planting observed growth and development, to understand the authenticity of the forage field of seed germination.

       By laboratory tests the quality of the grass seed

       Can forage seed purity was measured in the laboratory to determine the content of selected forage seed impurities non grass grass, and learn about the clarity of the seed; can be observed in the light incubator OK grass seed germination rate, germination potential and vigor index to determine the level of grass seed viability; isozyme electrophoresis analysis to distinguish genetically modified varieties. The work is generally done by professional organizations and professionals.

       Sensory identification method to determine the quality of the grass seed

       1. Visual inspection: the seeds of grain plumpness with the naked eye, uniformity, impurities and incomplete grain how much color is normal, whether the pest, gall or mildew, as well as the seed external features such as the presence or absence of grass seed Mans and other aspects of the case.

       2. Olfactory test: with the smell, to determine whether the grass seed rotten, spoiled or smell with the smell buds seeds, seed sent a mold with a sour or alcohol, just open the bag in this way sometimes also be used for the identification of mixed seeds such as alfalfa seeds mixed with sweet clover seeds spicy sweet clover seed.

       3. Tactile inspection: main feel simple judgment seed moisture content, insert your hand into the seed bag feel loose, slippery seeds, small resistance, sound, grasping seeds, seeds easily from the hands of living less water, or moisture content.

       4. The teeth feel Inspection: with his teeth gently increase the pressure to cut off the seed grain, if it feels effortless, crisp sound, the grain face powder out the end face of the hard plasmid neat, low moisture content.

       5. Hearing test: grab a handful of seeds hold on tightly, fingers, listening without rustling sound, peel seed grabbed shaking or stirring up listening to the sound, generally louder the sound, the less moisture content.

      Fourth, through the grass seed label to identify

       The color of grass seed to validate a certification label, there are three, namely, red, yellow, blue, red test varieties, the yellow pilot varieties, the blue field production varieties; grass seed sales on the label will generally indicate an seed forage species type, variety name, origin, seed business license number, quality indicators, quarantine certificate number, net weight, production date, manufacturer's name, address, contact details, etc., can also tag content to determine the initial seed quality and reliability. Buy seeds, buy reputable grass seed production and supply units, and not just freeloaders, so as not to be deceived, provincial, municipal and county animal husbandry station or forage station has a supply of seeds and planting households to provide the necessary technical guidance and services. In addition, the purchase of grass seed to ask for proof of purchase, cultivation and planting instructions to ensure seed quality and reliability.
