Problems solved by technology

[0003] Among the existing anti-drought agents, the passive anti-drought measures are mainly imposed on a certain drought-resistant point (such as reducing soil water evaporation or reducing transpiration or increasing plant internal hormones or adjusting leaf stomata opening, etc.), without sufficient Use the adaptability of crops to drought to actively resist drought. At the same time, rice is different from other dryland crops. Its growth environment and plant itself have much higher water requirements than dryland crops. Seasonal drought affects double-cropping rice. The impact on growth is much higher than that of other dryland crops. Therefore, according to the growth pattern of double-cropping rice and the characteristics of seasonal drought, the stomatal switch will be controlled, the polymer organic matter will form a film to prevent water and disperse, promote the growth of crop roots, promote plant photosynthesis and promote tillering. The combination of regulatory substances such as occurrence and development can slow down the harm of seasonal drought to double-cropping rice and can effectively increase the yield and variety of compound agents. the meaning of

Embodiment 1

[0048] Embodiment 1 greenhouse test effect

[0049] A. Experimental Design and Methods

[0050] The experiment was carried out in the greenhouse of the Institute of Soil, Fertilizer, Resources and Environment, Jiangxi Academy of Agricultural Sciences in 2013 and 2014. The rice was planted in pots, and each pot was filled with 20kg of soil. The pot soil was taken from the paddy field in Tujia Village, Bayi Township, Nanchang County. The soil The pH value is 5.72, the organic matter is 2.35%, the available nitrogen is 106mg / kg, the available phosphorus is 18.6mg / kg, and the available potassium is 81mg / kg. The early rice is made of Ganxin 203 (Jiangxi Modern Seed Industry Co., Ltd.), and it is sown on March 22. Transplant on April 25th, transplant 3 bushes in every pot, and 2 grain seedlings in every bush, spray the drought-resisting agent of the present invention on June 20 and set it as the compound agent group, and the control group only sprays clear water and is set as the cl...

Embodiment 2

[0060] Embodiment 2 field application test effect

[0061] A Experiment design and method

[0062] Based on the greenhouse pot test results in 2013 and 2014, the early and late rice in 2015 selected the drought-resistant agent formula of the present invention to apply in the field respectively, and compared with the control (spraying water). The test was carried out at Ji'an Agricultural Science Institute. The early rice variety Ganxin 203 (Jiangxi Modern Seed Industry Co., Ltd.) and the late rice variety Rongyou 225 (Jiangxi Jinshan Seed Industry Co., Ltd.) were tested. The early rice was transplanted on April 25, with a row spacing of 15.6×20cm, and the late rice was transplanted on July 28, with a row spacing of 20×20cm. The early rice was transplanted at the full heading stage on June 26, and the late rice was applied at the tillering stage on August 20. And the spraying of clear water (respectively set as compound agent group, clear water group), there is no wind or rain...

Abstract

The invention belongs to the field of crop production and discloses a seasonal drought relieving and high yield ensuring compound agent for double cropping rice. The compound agent includes an early-season rice special type and a later-season rice special type. The early-season rice special type includes, by weight, 50% of hydroxyethylcellulose, 20% of amino acid raw powder, 15% of monopotassium phosphate, 10% of potassium fulvate, 2.5% of zinc sulfate, 2% of prohexadione calcium, 0.2% of compound sodium nitrophenolate, and 0.05% of abscisic acid; and the later-season rice special type includes, by weight, 30% of hydroxyethylcellulose, 30% of amino acid raw powder, 20% of potassium fulvate, 10% of monopotassium phosphate, 5% of Kang polyphenol, 4.8% of zinc sulfate, and 0.2% of sodium alpha-naphthylacetate. In the formula, comprehensive drought resistant capability of rice is improved through several ways. The compound agent is quick in effects, has long lasting time and has good effects.

Description

technical field [0001] The invention belongs to the field of crop production and relates to a rice drought alleviating agent. Background technique [0002] Double-cropping rice is the main planting mode of rice in southern my country. Due to two crops a year, the total output of double-cropping rice is 900 kg / mu, and the high-yield field reaches 1300 kg / mu, which is an average increase of more than 60% compared with one-cropping rice. my country's double-cropping rice The planting areas are mainly distributed in 10 provinces including Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Guangdong, Guangxi, Hainan, Yunnan, and Fujian, with a total area of ​​10 million hm 2 Left and right, double-cropping rice production has made an important contribution to solving the problem of food security in southern my country where there are many people and little land. The double-cropping rice area is traditionally a high-water area with large precipitation in the previous year. However, due to th...
