Embodiment Construction

[0016] The present invention will be described in further detail below.

[0017] 1.1 Test materials and soil conditions

[0018] The cotton variety tested was Zhongmian 79. The field experiment was carried out in 2013 at the South Field of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences in Baibi Town, Anyang City, Henan Province. The test field is a multi-year continuous cropping cotton field, loamy fluvo-aquic soil, medium fertility, 0-20cm soil contains 1.51% organic matter, 0.083% total nitrogen, available phosphorus (P 2 o 5 )30mg·kg -1 , available potassium (K 2 O) 158mg·kg -1 .

[0019] 1.2 Experimental design

[0020] Foliar fertilizer formula ingredients: urea, potassium dihydrogen phosphate, zinc sulfate, gibberellin. Two formulations were designed, formulation 1: urea 1% + potassium dihydrogen phosphate 0.5% + zinc sulfate 0.1% + gibberellin 20mg·L -1 ; Formula 2: urea 1% + potassium dihydrogen phosphate 0.5% + zinc sulfate ().1...

Abstract

The invention discloses leaf fertilizer capable of promoting early growth and development of a cotton plant. The leaf fertilizer is an aqueous solution, and the active ingredients of the leaf fertilizer are composed of common urea, potassium dihydrogen phosphate, zinc sulfate and gibberellin. The invention further relates to a preparation and use method for the leaf fertilizer. The leaf fertilizer provided by the invention is sprayed onto the leaves during the fifth to sixth true leaf stage of the cotton plant, and is sprayed for one time in ten days and for 3 to 4 times continuously, so that vegetable growth and reproductive growth of the cotton plant can be coordinated and flower bud occurrence is promoted.

Description

technical field [0001] The invention relates to the field of agricultural fertilizer production, in particular to a foliar fertilizer capable of promoting the growth and development of cotton in the early stage and a preparation method thereof. Background technique [0002] Cotton is an important economic crop in my country, and lint production is the economic output of cotton. The bud development of cotton determines the economic yield of cotton to a certain extent. Spraying foliar fertilizers from the cotton seedling stage to the bud stage can play a role in strengthening the seedlings, coordinating the vegetative growth and reproductive growth of cotton, promoting the budding of cotton, and laying the foundation for high cotton yield. [0003] At present, there are many types of foliar fertilizers on the market, but foliar fertilizers suitable for cotton are still rare, and the cost performance is not high, and the effect is not ideal. Contents of the invention [000...
