Embodiment

[0027] The fertilization formula raw material composition and the ratio thereof of the present invention make the common rice seed Huanghuazhan grain naturally increase fragrance as follows:

[0028] Raw material Kg / mu

[0029] MgCl 2 5.52 + 0.83

[0030] MnCl 2 8.53 + 1.28

[0031] CuCl 2 1.49 + 0.22

[0032] ZnCl 2 2.16 + 0.32

[0033] Molybdic acid 0.24 + 0.04

[0034] Citric acid 3.91 + 0.58

[0035] Tartaric acid 3.91 + 0.58

[0036] Malic acid 3.91 + 0.58

[0037] Bagasse 460 + 69.

[0038] The fertilization period and method of the above fertilization formula are:

[0039] 1) When plowing the paddy field, apply bagasse at 460 kg per mu and mix with the soil plow layer

[0040] 2) When transplanting seedlings, apply KCl 15 per mu + 2.25Kg, urea 15 + 2.25Kg, calcium magnesium phosphorus 100 Kg.

[0041] 3) In the mid-tiller stage, evenly water and MgCl per acre 2 5.52 + 0.83, MnCl 2 8.53 + 1.28, CuCl 2 1.49 + 0....

Abstract

The invention relates to a formula and a fertilizing process for naturally increasing the fragrance of the grains of Huanghuazhan paddy rice. The fertilizing formula comprises MgCl2 5.52+ / -0.83 Kg / mu, MnCl2 8.53+ / -1.28 Kg / mu, CuCl2 1.49+ / -0.22 Kg / mu, ZnCl2 2.16+ / -0.32 Kg / mu, molybdic acid 0.24+ / -0.04 Kg / mu, citric acid 3.91+ / -0.58 Kg / mu, tartaric acid 3.91+ / -0.58 Kg / mu, malic acid 3.91+ / -0.58 Kg / mu, and sugar cane bagasse 460+ / -69 Kg / mu. The fertilizing method comprises the steps that: when a rice field is plowed, sugar cane bagasse is uniformly mixed with a topsoil layer according to an amount of 460Kg / mu; during seedling transplanting, 15 Kg / mu of KCl, 15 Kg / mu of urea, and 100 Kg / mu of calcium-magnesium-phosphorous is applied; and (3) at a mid-tillering stage, 5.5 Kg / mu of MgCl2, 8.53 Kg / mu of MnCl2, 1.49 Kg / mu of CuCl2, 2.16 Kg / mu of ZnCl2, 0.24 Kg / mu of molybdic acid, 3.91 Kg / mu of citric acid, 3.91 Kg / mu of tartaric acid, and 3.91 Kg / mu of malic acid which are uniformly mixed by using water are applied. With the process, plant C / N, N / S and nutrient ratio can be controlled, the fragrance of common Huanghuazhan paddy rice grains can be naturally increased. Therefore, regional limitation of fragrant rice production and planting is overcome.

Description

technical field [0001] The invention belongs to the technical field of natural aroma enhancement of common rice seeds, and in particular relates to a formula fertilization technology for natural aroma enhancement of rice seed Huanghuazhan grains. Background technique [0002] Fragrant rice has long enjoyed a high reputation not only for its aroma but also for its superior nutritional quality. In recent years, the demand for fragrant rice in Europe and the United States has also been increasing. The price of famous fragrant rice in the international market is more than twice that of ordinary rice. In 2008, even There are also "restricted exports" of Thai fragrant rice and Basmati fragrant rice and "restricted supply" in supermarkets. Thailand, India, Pakistan, and Taiwan Province of my country are mainly seizing the international fragrant rice market; and South Africa, Japan, Iran, Bangladesh, etc. are also potential fragrant rice exporters; Before 2000, it was necessary to i...
