Chapter 152 Cultivating Grass Seeds In a dedicated Yang's mind sank into the seed store, and then his consciousness focused, and bags of various grass seeds appeared on the store's shelves. Grass species are roughly divided into two categories. One type is various natural grass seeds collected from the Urat grassland in Inner Mongolia Province, mainly Mongolian ice grass, Astragalus membranaceus, Artemisia ordosica, etc. The other type is the grass seeds from high-altitude areas collected by Alfalfa Agriculture and Animal Husbandry from Gannan, mainly including slender-stemmed ice grass, cold-land bluegrass, awnless bromegrass, red fescue and other grass seeds. In addition, a variety of poisonous weeds were collected, including crazy grass, wolfsbane, mutant astragalus, small-flowered thorny beans, drunken horse grass, and ox-heart holly. Each poisonous weed has its own characteristics, but they are undoubtedly lethal to humans and livestock. Urad and Gannan grasslands are both important livestock production bases, and animal husbandry mainly utilizes natural grasslands. However, the degradation of grassland vegetation and the sharp decline in forage production have put the grassland animal husbandry economy into a difficult situation. When the diversity of grassland plants decreases, poisonous weeds will breed and spread in naturally degraded grasslands due to their well-developed root systems, resistance to drought, cold, barrenness, and strong vitality. The massive growth of poisonous weeds is an important sign of grassland degradation and also a sign of self-repair of grassland vegetation.
But for Guo Yang, although the harm caused by poisonous weeds is great, their germplasm characteristics are extremely attractive. It would be interesting if the excellent stress resistance genes of noxious weeds could be cloned into newly cultivated forage grass seeds. After sorting out my thoughts for a while, Guo Yang started to get busy. First, familiarize yourself with the characteristics of the plant varieties: The drunken horse Achnatherum splendens, which causes livestock to become depressed and foam at the mouth after eating it, and in severe cases, they become unstable when standing, stagger when walking, and stagger like being drunk. Pedicularis, a poisonous weed with strong vitality but a bad smell; Sophora alopecuroides is mainly distributed in sandy land, saline-alkali land and desert Gobi. It has a special smell and livestock generally do not actively eat it. Stipa... Bromus inermis… Poa angustifolia… The arrow-leaved ligustria... After spending some time getting familiar with the grass seeds brought back from Gannan, Guo Yang began to cultivate new grass seeds. This is a boring process. According to the expected characteristics, combine the varieties one by one to see how likely the seed store is to succeed in the combination. Because most of the forage grass species collected are of different species, the chances of successful cultivation are naturally greatly reduced. Without any certainty, Guo Yang would not try it rashly. Unless he had an incredible attribute, he would choose to take a gamble. Try again and again. Ding…… Sequence 1:
[Type]: Forage grass 【Parent】：Paternal 【Variety】：Mongolian Ice Grass 【Characteristics】: Agropyron genus of the Poaceae family, mainly distributed in sandy soil or sandy grassland, not only has extremely high feeding value, but also has a variety of resistance genes that can be used for crop improvement... Sequence 2: [Type]: Forage grass 【Parent】：Maternal 【Species】：Wolfsbane 【Features】：Slightly Guo Yang chose to cultivate. The next step was to choose the production area. Without hesitation, we chose the Urat grassland area. The next step is to select the parental traits that need to be retained. Guo Yang first selected the resistance gene of Mongolian ice grass, and then selected the inhibitory effect of wolfsbane root secretions on other weeds. At this time, the cultivation interface shows that 19 points of natural energy are required, but the success rate is as high as 81%. Damn it! Guo Yang couldn't help but exclaim. This success rate is incredible! I have been busy for a while, but probably because the varieties are not compatible, the success rate is often as low as 3-4%. For some traits, even if they are slightly increased, the breeding success rate will drop a little. The success rate is no different from gambling. Guo Yang, who has always been a non-African, looked at the characteristics of the species, which were really ordinary, and there was really no need to waste natural energy to gamble on that little probability. But the success rate of this combination of ice grass and wolfsbane was as high as 81%, which was a blessing from God! Guo Yang thought about it and it seemed that there were no special traits that needed to be added or enhanced. So I chose to cultivate. After a while of waiting, a new variety of forage grass appeared in front of Guo Yang. [Type]: Forage grass 【Variety】：To be named [Characteristics]: Rich in nutrients, good palatability, fast growth, drought resistance, cold resistance, salt resistance, wind and sand resistance, and barrenness resistance. It can be used for windbreak and sand fixation, and the secretions of its roots have an inhibitory effect on poisonous weeds. Guo Yang was immediately attracted. Do root secretions have an inhibitory effect on poisonous weeds? Isn’t it just for this unique plant that all this effort was spent? Guo Yang quickly named it, taking one character from each of his parents, Ice Wolf Grass! It is not difficult to understand from the introduction of the variety characteristics that ice wolf grass has a strong competitive inhibitory effect on poisonous weeds such as wolfsbane. If wolfgrass is reseeded on degraded grasslands, the reproduction of poisonous weed species will be inhibited, and high-quality forage grass will gradually resume growth, making prevention and control more scientific, economical, and environmentally friendly. In addition, ice wolf grass has the characteristics of being adaptable to living conditions, growing fast, and having high forage value. perfect. Guo Yang smiled contentedly. It only took 19 points of natural energy to breed such a comprehensive variety, so it was worth the effort. With the first successful experience, Guo Yang did not hesitate and continued his breeding business. And slightly lowered the requirements. He also preserved some slightly more distinctive varieties.
Perhaps it was precisely because of this mentality that Guo Yang soon reaped rewards in the cultivation of alpine forage grass. Ding…… [Type]: Forage grass 【Variety】：To be named 【Characteristics】: Annual green manure and leguminous forage, drought-resistant, cold-resistant, saline-alkali-resistant, protein content higher than 25%, root secretions have an inhibitory effect on poisonous weeds such as Achnatherum splendens and Crazy Grass... Guo Yang looked at the plant icon in the seed store and felt that it looked so much like the arrowroot pea. The only difference was that its leaves were a distinct purple color. Guo Yang couldn't help singing, "She is just my sister. My sister said that purple is very charming..." Just name it purple arrow pea. The alpine grasslands in China are lacking in leguminous forage, and the protein content of existing alpine forage is generally insufficient, so livestock often lack nutrition when gaining weight. The emergence of purple arrow pea just fills this gap. Moreover, its inhibitory effect on poisonous weeds can play an important role on the Gannan grassland. It can also be promoted to the Qinghai-Tibet Plateau, where it can generate huge economic value. "Huh, finally everything is ready. Now both the Urat Grassland and the Gannan Grassland have corresponding special-effect grass seeds. We just need to get some special grass seeds as supplements." Guo Yang muttered to himself, and then began to cultivate grass seeds. after one day. Guo Yang came out of the laboratory with satisfaction. This time he cultivated a total of 6 new forage grasses, in addition to ice wolf grass and purple arrow pea. There are also king grass and white wormwood that are suitable for growing in extremely arid desert areas. Needle grass, a pioneer plant in rocky desertification areas, can promote the positive recovery of soil and vegetation in rocky desertification areas, reduce soil erosion and increase soil organic matter. As well as the bitter weed cultivated from the two poisonous weeds, it is a highly toxic weed all year round and the whole plant is poisonous. However, its extract has a strong inhibitory effect on wolfberry aphids and pathogens of cucumber and tomato, and when the concentration of bitter elm in feed or drinking water reaches 1%, it can reduce the number of coccidia oocysts in livestock. Its insect-resistant and fungicidal properties are tailor-made for plant-derived pesticides. Isn't Quanwang Biotechnology going to roll? I guess the bitter grass must meet its requirements. With the new grass seeds, Guo Yang naturally wants to use them as soon as possible. Whether it is the 60 mu of desert grassland in Urad, the Gannan grassland, or the environmental governance of Minqin Sand Wo, it can play a significant role. But before that, the genetic breeding laboratory must be established first. (End of this chapter)
