Description
Technical Field
The invention relates to the technical field of oat saline-alkali resistance planting, in particular to a saline-alkali resistance reagent for improving forage oat and a use method thereof.
Background
The salinization of soil is an important factor for limiting the yield and quality of crops, and the conditions of poor seed germination, reduced biomass, reduced plant height and the like of the crops are easily caused by the salinization environment, so that the harvest yield and the nutritional quality of the crops are seriously influenced.
Oats are excellent crops for annual food and feed, and are widely popularized due to their excellent characteristics of strong adaptability, high growth rate, capability of forming a large amount of biomass in a short time, and the like. In recent years, with the change of market demand and planting system, a large amount of oat is used as hay and silage for livestock to eat, so that the domestic oat grass demand is continuously expanded. Oat forage grass is an important component of daily ration of livestock, particularly, livestock husbandry in northwest, north China and other areas is developed, and a large amount of forage grass oat is needed, however, environmental conditions in the areas are mostly mountainous areas or mountains, rainfall is low, irrigation demand is large, and soil salinization phenomenon is common. Therefore, the forage oat is inevitably affected by saline-alkali stress in the planting process, so that the yield is reduced, and the nutrition and the feeding quality are reduced.
The cultivation measure reported in the current research on improving the yield and quality of oats in a saline-alkali environment is to apply an exogenous reagent to the oats, wherein the applied substance is usually H 2 S，H 2 O 2 And salicylic acid and the like. However, these agents all exhibit various drawbacks during use: wherein H 2 S is a highly toxic and flammable gas, has a certain saline-alkali resistance, but is complex to operate and has certain harm to a human body; h 2 O 2 Weak acid is easy to react with alkaline fertilizer to lose efficacy in the using process, is difficult to store and is easy to decompose at higher temperature; the amount and period of application of salicylic acid are determined specifically according to the degree of salt stress and growth of oats, and the effectiveness thereof is further examined.
At present, agents which are added externally to improve the stress resistance of crops are mostly single compounds, and related experiments are lacked to demonstrate that different application methods can affect the crops. The single crop growth regulator has a single effect on the growth and development of crops, and simultaneously has low effectiveness due to no synergistic effect with other growth regulators, the problem can be effectively solved by compounding the plant growth regulators with different action mechanisms, and researches on the combination of various mineral nutrients and plant regulators in which modes is favorable for improving the yield and quality of the oat are few, so that the researches on the reagents with different concentrations and the application methods thereof have important significance on the yield and quality improvement of the oat in the saline-alkali environment. Exploring the application method of the exogenous reagent can enable the reagent to better play a role, and reducing the using amount so as to save the cost. At present, related researches on improving the saline-alkali resistance of crops by a cultivation method of adding a reagent from an external source at home and abroad are rarely reported, and effective addition combinations and matched application methods are particularly rare.

After 5 days of growth, the fresh seedling weight, the dry root weight and the root length of 10 groups of oat seedlings in the spraying and irrigating mode are measured, the average value of 10 groups is taken as final data, and the specific result is shown in tables 1-2; the stem-leaf ratio and crude protein content of oat were determined, and the specific results are shown in tables 3-4.
Table 1: data for spraying anti-saline-alkali reagent
The data in the table show that after the saline-alkali resistant reagent in the embodiment 7 is sprayed, the oat has a good growth state in a saline-alkali stress environment, the fresh weight of the oat is increased, and the dry weight of seedlings and roots is also improved; in the comparative example, the growth state of the oats was inferior to that of the oats in the example, but the growth state was slightly improved compared to the oats to which the saline alkali resistance agent was not sprayed in the control group.
Table 2: data for irrigating saline-alkali resistant reagent
The data in the table show that after the saline-alkali resistant reagent in the example 7 is irrigated, the oat has a good growth state in a saline-alkali stress environment, the fresh weight of the oat is increased, and the dry weight of seedlings and roots is also improved; in the comparative example, the growth state of the oats was inferior to that of the oats in the example, but the growth state was slightly improved compared to the oats to which the saline alkali resistance agent was not sprayed in the control group.
The data in the tables 1 and 2 are compared to find that spraying the saline-alkali resistant reagent is more beneficial to improving the growth condition of the oat compared with irrigating the saline-alkali resistant reagent.
Table 3: data for spraying anti-saline-alkali reagent
The data in the table show that after the saline-alkali resistant reagent is sprayed, the stem-leaf ratio, the crude protein content and the crude fiber content of the oats in the examples 1-12 are all higher than those of the oats in the comparative example and the control group, and the saline-alkali resistant reagent can effectively improve the growth state of the oats and reduce the influence of a saline-alkali environment on the oats.
Table 4: data for irrigating saline-alkali resistant reagent
It can be known from the data in the table above that after the saline-alkali resistant reagent is irrigated, the stem-leaf ratio, the crude protein content and the crude fiber content of the oats in the examples 1-12 are all higher than those of the oats in the comparative examples and the control group, and the saline-alkali resistant reagent in the application can effectively improve the growth state of the oats and reduce the influence of the saline-alkali environment on the oats.
The data in the tables 1 and 2 are compared to find that spraying the saline-alkali resistant reagent is more beneficial to improving the growth condition of the oat compared with irrigating the saline-alkali resistant reagent.
3. Simulating a saline-alkali environment to prepare the experimental oat material again, and then taking the saline-alkali resistant reagent in example 7 as an example, spraying the saline-alkali resistant reagent on the leaves of 3-leaf stage seedlings in each pot, wherein the ratio of the saline-alkali resistant reagent to the leaves of the 3-leaf stage seedlings in each pot is 18: and the spraying amount is about 15mL per basin every time when the Chinese herbal medicine is sprayed for 1 time when the Chinese herbal medicine is sprayed for 3 times, 6 times and 9 times respectively. Two groups of repeat spraying times are set according to different spraying times, random variables are adopted for grouping, the crude protein content and the crude fiber content in the oat are measured after 10 days of growth, and specific results are shown in a table 5.
Table 5: crude protein content
| Spraying for 3 times | Spraying for 6 times | Spraying for 9 times | |
| Crude protein content (%) | 5.73 | 6.5 | 5.93 |
| Crude fiber content (%) | 24.1 | 25.4 | 24.6 |
As can be seen from the data in the table, the continuous spraying of the salt and alkali resistant reagent for 6 times on the oats in the salt and alkali stress state can effectively improve the content of crude protein and crude fiber in the oats.
