Description
Technical Field
The invention relates to a chemical preparation for improving the transplanting survival rate of sweet potatoes and the quality of sweet potato seedlings in saline-alkali soil, and belongs to the technical field of crop planting.
Background
The method has the advantages that large areas of saline-alkali beach land blocks exist in China, saline-alkali stress is an important factor for inhibiting crop yield, sweet potatoes are one of the most important grain crops in China, and the traditional sweet potato cultivation method in saline-alkali land has the problems of low seedling rate, slow growth, low yield, poor quality, overhigh cost and the like.
The inventor provides a simplified high-yield cultivation technology for sweet potatoes in saline-alkali soil through continuous research and exploration, the technology can normally grow in the soil with the salt content of 0.3-0.5%, high yield is obtained, and the problems of seedling shortage, ridge breaking, slow medium-term growth and serious yield reduction of the sweet potatoes in the seedling stage in a traditional cultivation mode are solved. However, the later practical process finds that the technology has small improvement range on the survival rate of the potato seedlings of the saline-alkali intolerant variety; in the cultivation mode, the quality of the potato seedlings is still not satisfactory and the yield needs to be improved no matter the potato seedlings are saline-alkali tolerant or saline-alkali intolerant.
Disclosure of Invention
Aiming at the problems of poor quality of sweet potato seedlings in the seedling stage of the sweet potatoes and the like in the prior art, the invention provides a chemical reagent for improving the transplanting survival rate of the sweet potatoes and the quality of the sweet potato seedlings in saline-alkali soil.
The technical scheme adopted by the invention for realizing the purpose is as follows:
the invention provides a chemical preparation for improving the sweet potato transplanting survival rate and the potato seedling quality in saline-alkali soil, which consists of methyl jasmonate and 2-N, N-diethylaminoethanol caproate.
Further, the chemical preparation preferably contains 20-40 mg of methyl jasmonate and 40-60mg of diethylaminoethanol 2-N, N-hexanoate per L of chemical preparation.
Further, it is most preferable that the total amount of the chemical preparation per L contains 22.4mg of methyl jasmonate and 56.6mg of 2-diethylaminoethanol N, N-hexanoate.
Furthermore, each L of the chemical preparation also comprises 10g of triethanolamine, 14mg of ethylene diamine tetraacetic acid, 10g of plant asphalt and 10mg of nisin.
The chemical preparation for improving the sweet potato transplanting survival rate and the sweet potato seedling quality in the saline-alkali soil provided by the invention has the following specific using method:
(1) firstly, uniformly mixing triethanolamine, ethylene diamine tetraacetic acid and plant asphalt, heating to 80 ℃, then keeping the temperature and stirring for 1.5h, cooling to room temperature, adding nisin, and uniformly stirring to obtain a mixed solution A;
(2) uniformly mixing methyl jasmonate and 2-N, N-caproic acid diethylaminoethanol ester, adding purified water to make up to 1L, uniformly stirring, adding the mixed solution A, and uniformly stirring to obtain the product;
(3) soaking potato seedling root about 10cm in the medicinal liquid for 25-35min, and taking out.
The inventor finds out in the process of attempting to improve the saline-alkali tolerance of sweet potatoes in seedling stage: the saline-alkali resistance of the sweet potatoes can be improved by soaking the roots with the methyl jasmonate solution with a certain concentration, the activity of antioxidant enzymes at the roots of the sweet potatoes is obviously improved, the survival rate of the sweet potato seedlings is obviously higher than that of a control under 0.3 percent of salt alkalinity, but the biomass of the sweet potato seedlings is also obviously reduced compared with that under normal conditions; DA-6 (2-N, N-diethylaminoethanol caproate) is a safe and efficient crop high-yield and high-quality stress-resistant gene inducer, can enlarge plant leaf area, improve chlorophyll content and photosynthetic rate, prolong the functional period of leaves, promote synthesis and accumulation of plant carbohydrates and improve crop biomass, but under the saline-alkali condition, the promotion effect is inhibited, and the quality of sweet potatoes in the seedling stage cannot be improved. Through a large number of experiments, the inventor discovers that the survival rate of the sweet potatoes and the quality of the sweet potato seedlings under the saline-alkali condition can be greatly improved by matching under the condition of a specific proportion; the improvement range is far beyond the effect which can be generated by methyl jasmonate and 2-N, N-caproic acid diethylaminoethanol ester, and the synergistic effect is achieved; the effect is better when the composition is used together with other preparations.
The plant asphalt used in the invention is waste residue in the processing process of soybean oil.
The invention has the beneficial effects that: the chemical preparation provided by the invention can obviously improve the survival rate of sweet potato seedlings planted in the seedling stage of the sweet potatoes in the saline-alkali soil and the quality of the sweet potato seedlings, thereby realizing the high yield of the sweet potatoes in the coastal heavy saline-alkali soil; the chemical regulation and control formula provided by the invention lays a foundation for realizing high yield and high quality production of sweet potatoes in moderate saline-alkali soil; the invention changes waste into valuable by utilizing the plant asphalt and realizes the sustainable development of resources.
