一种香稻有机增香叶面肥A fragrant rice organic flavored foliar fertilizer 技术领域Technical field
本发明涉及香稻生产领域，特别涉及一种香稻有机增香叶面肥。The invention relates to the field of fragrant rice production, in particular to a fragrant rice organic fragrant foliar fertilizer.
背景技术Background technique
香稻是水稻中的珍品，以其清香可口的特色长期以来得到亚洲人的喜爱，近年来在美国、欧洲、中东和澳大利亚亦受到更广泛的青睐。尽管在国内外稻米市场上，香米的价格通常是普通非香稻米价格的2-3倍，但世界香米的消费量仍在逐年增长，这主要是因为香米具有独特的香气，它不仅能诱发人的食欲，而且能使人们在进餐时享受精神上的愉悦。为了获取香米利润的最大化，有些企业在稻米的加工过程中采用人工加香的手段来增加稻米的香气，这就与大田种植的香稻所释放的香气截然不同。因此，在香稻的生长过程中，通过一定的农艺措施来增加香稻的香气就显得尤其重要。以往的发明专利“一种香稻增香剂及其施用方法(专利号ZL 2010 1 0518779.8”，主要是由九二0、脯氨酸和氯化锌配制而成的水溶液，不能满足有机香稻生产的需求，可见，创制出香稻有机增香叶面肥，应用于有机香稻生产(亦可应用于绿色和无公害香稻生产)，促进高端浓香型香米的市场竞争力大幅度提高很有必要。Aromatic rice is a treasure in rice. It has long been loved by Asians for its fragrant and delicious characteristics. It has also been favored in the United States, Europe, the Middle East and Australia in recent years. Although the price of basmati rice is usually 2-3 times that of ordinary non-fragrant rice in the domestic and international rice market, the consumption of fragrant rice is still increasing year by year, mainly because fragrant rice has a unique aroma, which is not only It can induce people's appetite, and can make people enjoy spiritual pleasure when eating. In order to maximize the profit of fragrant rice, some companies use artificial flavoring to increase the aroma of rice during the processing of rice, which is quite different from the aroma released by the fragrant rice grown in the field. Therefore, in the growth process of fragrant rice, it is particularly important to increase the aroma of fragrant rice through certain agronomic measures. The previous invention patent "a fragrant rice flavoring agent and its application method (Patent No. ZL 2010 1 0518779.8", mainly an aqueous solution prepared from 920, valine and zinc chloride, cannot satisfy the organic fragrant rice The demand for production can be seen, creating an organic fragrant foliar fertilizer for fragrant rice, which is applied to the production of organic fragrant rice (also applicable to the production of green and pollution-free fragrant rice), and promotes the market competitiveness of high-end fragrant fragrant rice. Improvement is necessary.
