Background
Atriplex canescens (pursuing) Nutt, also known as atriplex canescens, is native to the midwestern region of the united states and is a feed shrub bred by 25 years of effort in units such as the agricultural test station of the colorado state university, the forestry bureau mountain forestry and the pasture test station of the agricultural department, and is known as a wonder and a biological desalter. The atriplex canescens is a perennial feed shrub, has no obvious trunk and many branches, and the annual crown width can reach 130 biomass. The leaf grows alternately and has a strip shape or a needle shape, the tip of the leaf is gradually sharp or blunt, the leaf is full-edged, without a handle, the front of the leaf is green, and the leaf has white powder particles. Atriplex canescens is mostly hermaphroditic, few individuals are hermaphroditic, the fruit is a gynecoid, and the surface of the gynecoid usually has four mutually separated wings. The seeds are elliptical or inverted oval, horseshoe-shaped.
Analysis of the anatomical structure of the leaves shows that atriplex canescens has structural characteristics of drought resistance, salt resistance and cold resistance. The upper and lower surfaces of the leaf have covering material, the surface has horny layer, the epidermal cell is large, the cell outer wall is thickened and arranged tightly, so as to play a role of protection, the fence tissue is developed, the cytoplasm is thickly distributed on the two sides of the leaf, the osmotic pressure of the cell can be increased, and the water absorption and storage capacity can be improved. The vascular bundles are closely arranged and have developed vascular tissues, the water delivery area of the leaves is increased, the rapid transfer of water is ensured, and the method is an important characteristic of the xerophyte. Atriplex canescens is a typical salt vesicle halophyte, and the salt vesicles are distributed on the front and back of the leaf. The morphological characteristics lead the atriplex canescens to have the excellent characteristics of fast growth, drought resistance, saline-alkali resistance, cold resistance, barren resistance and the like.
The annual precipitation of atriplex canescens native place is about 350 mm. According to the cultivation experiment of Qinghai province in arid areas, the atriplex canescens can grow well in the areas with annual precipitation of 250-350 mm. The atriplex canescens planted in the crataegia area with the annual average rainfall of only 105mm can still grow well. The common plants can not grow normally after the salt content in the soil exceeds 3 per mill, the atriplex canescens has extremely strong salt tolerance, the soil can grow normally when the salt content is below 15 per mill, the plants are stressed by the salt after more than 18 per mill, the shoot content of branches is reduced, the plant growth is severely inhibited after the salt content reaches 26 per mill, the plants can still survive, the branches and leaves at the base parts of the stems have no obvious withering or death symptoms of the whole plants, and the plants can still grow normally once the conditions are improved. The atriplex canescens cold resistance is also strong, and the critical lethal low temperature of the atriplex canescens is-42.97 ℃ which is measured by the exosmosis rate of 50 percent of electrolyte and is calculated by a Logistic equation. At a low temperature of-30 ℃, the electrolyte extravasation rate of the atriplex canescens is only 35.59%. In the natural overwintering state, the atriplex canescens decreases with the water content of the leaves, the fluidity of protoplasm becomes slow, the cell metabolism is weakened, the osmotic adjustment accumulation is realized, the water potential and the freezing point are reduced, the effect of a freezing protective agent is realized, and the cold resistance is enhanced. The atriplex canescens has high nutritive value, multiple plant nutritive indexes obviously exceed those of alfalfa and other plants, and the atriplex canescens has good palatability, high growth speed, large biomass and cutting resistance, and is the most valuable excellent feed for various livestock and wild animals. The atriplex canescens is also an excellent plant for saline-alkali soil improvement and water and soil conservation, and can effectively reduce the salt content of soil, accelerate the soil development and improve the soil fertility after the atriplex canescens is planted in the saline-alkali soil. The atriplex canescens has developed root system, can obviously retain water quantity in the rain washing process, and reduces the direct washing and conveying capacity of rain on the soil surface. Recent research also finds that the atriplex canescens can be inoculated with rare traditional Chinese medicine cistanche, and the content of active ingredients is higher, the quality is better, and the application value of the species is further improved.
The atriplex canescens is introduced into the deteriorated pasture in the west of China from 1976 to 1982, and the results show that the atriplex canescens can improve and recover the quality of the deteriorated pasture. At present, the atriplex canescens has been introduced in more than ten provinces of China, such as Xinjiang, inner Mongolia, Ningxia, Qinghai, Gansu, Liaoning, Shanxi, Hebei, Shandong and the like, and most areas can grow well and can blossom and bear fruits. Owing to the wide adaptability of the species to adversity stress, the feeding value and the excellent characteristics in various aspects such as soil improvement, water and soil conservation and the like, the four-wing atriplex canescens is expected to become a pioneer tree species for treating northwest desertification, coastal saline-alkali soil and yellow river mudflat in China. The ecological environment is improved by popularizing the planting of the atriplex canescens, a large amount of high-quality silage can be provided for the local livestock breeding industry, and the development of the cistanche deserticola industry can be driven. The method brings remarkable ecological benefits and huge economic benefits, and has important significance for ecological, efficient and sustainable utilization of coastal saline-alkali soil and yellow river delta saline-alkali soil in northwest arid and semi-arid regions of China.

Unless otherwise specified, the experimental methods, detection methods, and the like described in the following examples are conventional experimental methods, detection methods, and the like in the prior art.
Example 1: atriplex canescens seedling test
(1) Selection and soil preparation of breeding nursery
Selecting sandy soil land with good drainage and convenient irrigation as a seeding nursery. The soil is fully and deeply ploughed by a rotary cultivator with the depth of 30-40cm, leveled and without obvious big blocks to be sowed.
(2) Removing wings, impurities and fine selecting of atriplex canescens fruit
The method comprises the following steps: method for treating and growing seedlings of two 11 atriplex canescens seeds by fixing 60-mesh abrasive cloth on the seeds respectively2Placing the atriplex canescens fruit on the sand paper of one wood board, grinding the four wings of the atriplex canescens fruit surface with the sand paper of the other wood board (the surface of the sand paper is opposite), and sieving with 12-mesh steel sieve to remove powder impurities; and then, continuing to grind for the second time, further removing the residual fins on the surface of the seeds until no obvious fins are formed on the surface of the seeds (as shown in figure 3), and then screening out powder impurities by using a 16-mesh steel sieve to prepare the seeds for later use.
The second method comprises the following steps: spreading the completely dried seeds on cement ground with a thickness of 3-5cm, grinding with 40 mesh abrasive cloth by an Europe Laider wall surface grinder, grinding four wings of the surface of atriplex canescens fruit, and sieving with 12 mesh steel sieve to remove powder impurities. And then, continuing to polish for the second time, further removing the residual wings on the surfaces of the fruits until no obvious residual wings protrude on the surfaces of the atriplex canescens fruits (picture 3), and further screening out powder impurities by using a 16-mesh steel screen to obtain the fruits for later use. Compared with the first method for removing the four wings, the method can quickly remove the four wings on the surface of the atriplex canescens fruit in a large scale, and is more suitable for field breeding.
The four wings on the surface of the atriplex canescens fruit are removed by the two methods, so that firstly, the hard shell of the atriplex canescens can be slightly damaged, the seeds can absorb water and sprout easily, and the sprouting efficiency is improved; secondly, the empty seeds can be partially removed, so as to achieve the purpose of fine selection.
(3) The stratification treatment breaks the dormancy of the seeds and promotes the germination of the seeds
Selecting and removing wings, placing the fruits into plastic bags, freezing the fruits in a freezer for 24 hours, taking out the fruits, airing the fruits for one day, repeating the freezing and airing for two times to achieve the aim of triple freezing and triple airing, breaking dormancy and promoting seed germination.
(4) Soaking seeds in warm water
Adding hot water into a heat-insulating foam box, adjusting the temperature to 50-52 deg.C with a thermometer, pouring the atriplex canescens fruit into the prepared warm water (the volume of the hot water is 2-3 times of the total volume of the seeds), stirring, inserting the thermometer therein while observing the temperature of the hot water at any time, and adding the hot water at any time according to the temperature change to keep the temperature of the hot water at 50-52 deg.C. After scalding the seeds for 30m, the hot water is poured off and the seeds are washed several times with tap water. The seeds were then soaked in tap water for 12 hours and rinsed several times for further processing.
The high-temperature scalding seeds can increase the seed activity, improve the germination rate, shorten the germination time, enable the seeds to sprout neatly, and kill pathogenic bacteria and eggs on the surfaces of the fruits to reduce the morbidity. Meanwhile, the use of disinfectants such as potassium permanganate and sodium hypochlorite is reduced, and the environmental pollution can be reduced while the cost is reduced.
The saponin which inhibits germination can be removed by soaking the seeds with water, so that the germination time can be shortened, and the germination rate can be improved.
(5) Solution treatment of plant hormone, potassium nitrate and zinc sulfate
Treating the soaked and washed de-winged atriplex canescens fruit with phytohormone, potassium nitrate and zinc sulfate solution (675mg/L GA)3，2.6mg/L IAA，3.1mg/L BR，2g/L KNO3，0.25g/L ZnSO4) Soaking for two hours, washing with clear water once, and sowing.
Exogenous phytohormone (gibberellin, auxin and brassinolide) treatment helps to break seed dormancy and promote seed germination and rooting. KNO3K in (1)+As an activator of various enzymes, the activity of various enzymes is improved to a certain extent, cell membranes are partially repaired, and the activator can also participate in the induction of the biosynthesis of growth hormone in plants. Zinc is an indispensable element in seeds, is a composition substance of certain enzymes (such as respiratory enzyme) and is a catalyst in a redox process, and can improve the activity of oxidase. The potassium nitrate is an oxidant, and the catalytic action of zinc ions promotes the oxidation-reduction process inside the seeds, so that the seeds obtain more oxygen. Oxygen is also a necessary condition for seed germination, so that the dormancy of the seeds is released, the germination is promoted, and the germination rate is improved.
(6) Seed sowing
The nursery garden needs to be watered with enough bottom soil moisture before sowing, the treated fruits can be sowed by drill, each mat is 1m wide, the seeds are uniformly scattered on the mat, and then the mat is covered with sandy soil, and the thickness is 1-2 cm. The fruit can also be sowed in rows with row spacing of 30cm, and covered with sandy soil 1-2cm after ditching and sowing. When the covering sand is too shallow, the seeds are easy to cause dry buds due to dry and hard ground surface, the seedling emergence of the seeds is influenced due to too thick covering sand, and watering is carried out in time after sowing. The sandy soil is preferably prepared by uniformly mixing common soil and fine sand in a ratio of 1:2 and then covering. The fruits after the wings are removed are easier to cover, and the fruits are difficult to wash out after watering at the later stage, thereby ensuring the germination rate and saving the seeds.
The size of the winged fruit is about 10kg per mu. The seedlings are kept loose and moist before coming out of the soil, and water is sprayed once in the morning and evening by a watering pot, and drop irrigation can be adopted. The seeds begin to sprout 3-5 days after sowing, the sprouts reach the maximum value in the seventh day, and then sprout continuously, and the final germination rate is about 49%.
Through comparison and analysis with the atriplex canescens germination experiment reported at present, the germination method disclosed by the patent can obviously shorten the germination time while improving the germination rate (figure 4). 1, directly soaking the seeds for 12 hours, wherein the germination rate of the seeds is only 9 percent; treatment 2, the germination rate induced by low temperature after treatment at 40 ℃ is about 20%; treating 3, removing wings, performing lamination treatment, and blanching at 50 ℃ for half an hour to ensure that the germination rate is about 22%; treatment 4, removing wings, performing stratification treatment, blanching at 50 ℃ for half an hour, performing GA treatment, and ensuring that the germination rate is about 25%; treatment 5, after removing wings, performing lamination treatment, blanching at 50 ℃ for half an hour, and increasing the germination rate to 31% by adding potassium nitrate and zinc sulfate while performing GA treatment; 6, after removing wings, performing lamination treatment, blanching at 50 ℃ for half an hour, and mixing the three hormones, wherein the germination rate is about 37%; and 7, after the wings are removed, the three hormones are subjected to stratification treatment and are blanched at 50 ℃ for half an hour, the germination rate can reach 49 percent by the mixed treatment of the three hormones and the treatment of potassium nitrate and zinc sulfate, and the germination rate exceeds 35 percent after the fourth day of germination. Through the implementation of this patent, can also shorten the time of sprouting when showing improvement atriplex canescens germination rate.
(7) Post-emergence management of seeds
After seedling emergence, water management is enhanced, irrigation is carried out in time according to soil moisture content, and normal growth of seedlings is guaranteed. And the carbendazim and the metalaxyl-hymexazol are sprayed in time to prevent diseases such as stem rot, damping off and the like. After irrigation, the soil is loosened and weeded in time, and the soil is kept loose. When the seedlings grow to 10cm high, watering is performed as little as possible, root growth is promoted, and the transplanting survival rate is improved.
