Chapter 152 Cultivating Grass Seeds
In an exclusive laboratory.
Guo Yang's mind sank into the seed store, and then his consciousness condensed, and bags of various grass seeds appeared on the store shelves.
Grass species are roughly divided into two categories.
The first type is various natural grass species collected from the Urad grassland of Mongolia Province, mainly Mongolian ice grass, Shatawang, and Artemisia striata.
The other type is grass species in alpine areas collected by Alfalfa Agriculture and Animal Husbandry from Gannan, mainly including thin-stemmed wheatgrass, cold field bluegrass, awnless brome, purple fescue and other grass species.
In addition, a variety of noxious weeds were also collected, such as locoweed, wolfsbane, mutated astragalus, small-flowered spinach, drunken horse grass, cow's heart and so on.
Each poisonous weed has its own characteristics, but it is undoubtedly lethal to people and livestock.
Urad and Gannan grasslands are both important animal husbandry production bases, and animal husbandry mainly utilizes natural grasslands.
However, the degradation of grassland vegetation and the sharp decline in pasture production have put the grassland animal husbandry economy into trouble.
When the diversity of grassland plants decreases, poisonous weeds breed and spread in natural degraded grasslands due to their developed root systems, drought resistance, cold resistance, barrenness resistance, and strong vitality.
The proliferation of poisonous weeds is an important sign of grassland degradation and is also the self-repair of grassland vegetation.
But for Guo Yang, although poisonous weeds are harmful, their germplasm characteristics are extremely attractive.
It would be interesting if the excellent stress resistance genes of poisonous weeds could be cloned into newly cultivated 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 species:
Drunken horse splendens. After eating it, livestock will become depressed and foam at the mouth. In severe cases, they will become unstable, walk unsteadily, and stagger as if drunk, as if they were drunk. Performance;
Maxianhao, a poisonous weed with strong vitality, but has an unpleasant odor;
Sophora vulgaris, mainly distributed in sandy land, saline-alkali land and Gobi desert, has a special smell, livestock Generally do not actively eat;
Stipa...
Grassless brome...
Poa annua...
Areophylla...
It took some time to put Gannan After getting familiar with the grass seeds that were brought back, Guo Yang started cultivating new grass seeds.
This is a tedious process.
Combine the varieties one by one based on the expected characteristics and see how likely the seed store is to successfully combine them.
Because most of the forage species collected are of different species, the chance of successful cultivation is naturally greatly reduced.
If he was not sure, Guo Yang would naturally not try it rashly, unless he had the kind of unnatural attributes that he would choose to take a gamble.
Try again and again.
Ding...
Sequence 1:
[Type]: Forage
[Parent]: Male parent
[Variety]: Mongolian ice grass
[Characteristics]: Graminaceae Agropyron is mainly distributed in sandy soil or sandy grassland. It not only has extremely high feeding value, but also has a variety of resistance genes that can be used for crop improvement...
Sequence Two:
[Type]: Forage
[Parent]: Female parent
[Variety]: Wolfsbane
[Characteristics]: Briefly
Guo Yang chose to cultivate.
Then it was time to choose the production area. Without hesitation, I chose the Urad Grassland area.
The next step was to select the parental traits that needed to be retained. Guo Yang first selected the resistance gene of Mongolian wheatgrass, and then selected the inhibitory effect of Wolfsvenom root exudates on other weeds.
At this time, the cultivation interface shows that 19 points of natural energy are needed, but the success rate is as high as 81%.
Damn it!
Guo Yang couldn't help but exclaimed.
This success rate is a bit incredible!
It has been busy for a while, maybe because the varieties are not suitable, the success rate is often as low as 30-40%.
Some slightly increase the traits, and the breeding success rate will drop by a small amount.
The success rate is no different from gambling.
Guo Yang, who has always been a non-chief, saw that the characteristics of the breed were real and ordinary, and there was really no need to waste natural energy to bet on that probability. But the success rate of this combination of ice grass and wolfsbane can actually reach 81%, God is so kind!
Guo Yang thought for a while and found that there seemed to be no special traits that needed to be added or enhanced.
I chose to cultivate.
After waiting for a while, a new pasture species appeared in front of Guo Yang.
[Type]: Forage
[Variety]: To be named
[Characteristics]: Rich in nutrients, good palatability, fast growth, drought resistance, cold resistance, salt tolerance , resistant to wind and sand, resistant to barrenness, can be used to prevent wind and sand, and its root secretions have an inhibitory effect on poisonous weeds.
Guo Yang was immediately attracted.
Can root secretions inhibit poisonous weeds?
Isn’t it just for this unique plant that you have spent so much effort?
Guo Yang quickly named them, each with a word from its parent, Ice Wolf Grass!
It is not difficult to understand from the introduction of variety characteristics that wolfberry has a strong competitive inhibitory effect on poisonous weeds such as wolfsbane.
If wolfberry is reseeded on degraded grassland, the reproduction of poisonous grassland populations will be suppressed, and the growth of fine forage will gradually resume, making prevention and control more scientific, economical, and ecologically environmentally friendly.
Moreover, ice wolfgrass is suitable for growing, fast growing, and has high forage value.
Perfect.
Guo Yang smiled contentedly.
It only took 19 points of natural energy to breed such a comprehensive variety, and it was worth the hard work.
With his first successful experience, Guo Yang stopped writing and continued his breeding career.
And slightly lowered the requirements.
He also retained some slightly distinctive varieties.
Perhaps because of this mentality, Guo Yang soon also made gains in the cultivation of alpine forage.
Ding......
[Type]: Forage
[Variety]: To be named
[Characteristics]: Annual green manure and leguminous grass, resistant to drought, high cold, salt and alkali, protein content higher than 25%, root secretions are resistant to Splendoris splendens and Crazy Splendo. Poisonous weeds such as grasses have inhibitory effects...
Guo Yang looked at the plant icons in the seed store and felt that they looked so much like arrow peas. The only difference was that the leaves were obviously purple.
Guo Yang couldn't help singing a cappella, "She's just my sister. My sister said purple is very charming..."
He named it Purple Arrow Pea directly.
Domestic alpine grasslands are short of leguminous pastures. The protein content of existing alpine pastures is generally insufficient, and livestock are often not nutritious when growing fat.
The emergence of purple arrow peas just fills this gap.
And its inhibitory effect on poisonous weeds also happens to play an important role in the grasslands of Gannan.
It can also be promoted to the Qinghai-Tibet Plateau region, which will generate great economic value.
“Huh, we’re finally done. Now both the Urad Grassland and the Gannan Grassland have corresponding special grass species, and we can just get some unique grass species to supplement them.”
Guo Yang muttered to himself, and then started cultivating grass seeds again.
One day later.
Guo Yang left the laboratory with satisfaction.
This time he cultivated a total of 6 new grasses, in addition to ice wolfgrass and purple arrow pea.
There are also overlord grass and white sand wormwood that are suitable for growing in extremely arid desert areas.
Stipa, 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 sophora cultivated from two poisonous weeds, it is a highly poisonous weed all year round and the whole plant is poisonous.
However, its extract has a strong inhibitory effect on wolfberry aphids and pathogenic bacteria of cucumbers and tomatoes, and when the concentration of sourgrass in feed or drinking water reaches 1%, it can reduce the number of coccidia oocysts in livestock.
Its anti-insect and bactericidal properties are simply tailor-made for botanical pesticides. Doesn’t Quanwang Biotechnology want to roll up? Sophora japonica must fit the bill.
With the new grass seed, Guo Yang naturally wanted to use it as soon as possible. Whether it is the 600,000 acres of desert grassland in Urad or the grasslands of Gannan, environmental management in Minqin Shawo can play a considerable role.
But before that, the genetic breeding laboratory must be implemented first.
