Embodiment 1

[0047] A seedling concentrated biogas slurry foliar fertilizer suitable for transplanting cotton, which is made of the following concentrations of raw materials:

[0048]

[0049] Based on the above-mentioned raw materials, the effective content of nitrogen, phosphorus and potassium obtained is:

[0050]

[0051]

[0052] A kind of preparation method of seedling concentrated biogas slurry foliar fertilizer suitable for transplanting cotton, its steps are:

[0053] A. Heat the concentrated biogas slurry and control the temperature at 40 or 43 or 45 or 48 or 50°C;

[0054] B. Add the above raw materials into 700mL concentrated biogas slurry in sequence according to a certain proportion of urea, glycerin, ammonium nitrate, potassium nitrate, potassium acetate, dipotassium hydrogen phosphate, ammonium sulfate, and magnesium sulfate, stir evenly, and cool; the temperature is controlled at 20 or 22 or 24 or 25°C;

[0055] C. Then use the concentrated biogas slurry at norm...

Embodiment 2 to Embodiment 13

[0058] A seedling stage concentrated biogas slurry foliar fertilizer suitable for transplanting cotton, which is made of the concentration (g / L) of the following raw materials:

[0059]

[0060] Its preparation steps are identical with embodiment 1.

[0061] Since the biogas slurry is rich in natural organic compounds and the solution is weakly alkaline, the raw materials for fertilizer preparation are all neutral (urea, potassium nitrate, etc.) or slightly alkaline (dipotassium hydrogen phosphate, potassium acetate, etc.) raw materials to maintain concentration The original physical and chemical properties of the biogas slurry; the half-price of the hydrated ions of the raw materials used is small, so the solubility is high, the ratio between the types of raw materials and the different forms of the same element is reasonable, and it is not easy to react with metal ions such as calcium, magnesium, zinc, and iron in the liquid fertilizer Nutrients become invalid; the variou...

Embodiment 14

[0063] A kind of application of concentrated biogas slurry foliar fertilizer at seedling stage in transplanting cotton seedlings (transplanting at cotyledon flattening stage): its steps are:

[0064] A. Conducted in a temperature-controlled and dimming greenhouse (20°C or 26 or 30 or 34 or 37 or 40°C), the test was carried out in March 2016;

[0065] B. Taking Jimian 228 as the tested variety, artificial germination in the room, germination and seedling cultivation in sandy soil;

[0066] C. Transplant when the cotyledons are flattened, and carry out the test the next day after transplanting. The test sets clear water and concentrated biogas liquid stock solution (using membrane concentration technology, which is formed by filtering and concentrating the fermented chicken manure mixture step by step, specifically For: a biogas slurry concentrate and engineering preparation method: CN104058799B[P].2014), 3 treatments of concentrated biogas slurry foliar fertilizer (described in...

Abstract

The invention discloses a seedling-period concentrated biogas slurry leaf fertilizer applicable to cotton transplanting and application thereof. The seedling-period concentrated biogas slurryleaf fertilizer is prepared from urea, ammonium nitrate, potassium nitrate, potassium acetate, dipotassium phosphate, ammonium sulfate, magnesium sulfate and glycerinum in a certain ratio. A preparation method comprises the following steps: A, heating concentrated biogas slurry; B, sequentially adding urea, glycerinum, ammonium nitrate, potassium nitrate, potassium acetate, dipotassium phosphate, ammonium sulfate and magnesium sulfate into 700mL of the concentrated biogas slurry, uniformly stirring, and cooling; and C, fixing the volume by using normal-temperature concentrated biogas slurry, thus obtaining the seedling-period concentrated biogas slurry leaf fertilizer. The seedling-period concentrated biogas slurry leaf fertilizer is safe in quality, can be biologically decomposed and utilized, is environmental-friendly, is simple and convenient to operate and reasonable in nutrition formula; pot experiments and field plot experiments show that the problems that the yield and the quality are affected as slow seedling reviving in a seedling period, late development and late maturing are caused by nutrient absorption deficiency due to root system damage and activity reduction are solved, and the fertilizer is easy to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of foliar fertilizer, and more specifically relates to a seedling-stage concentrated biogas slurry foliar fertilizer suitable for transplanting cotton, and also relates to a use of a seedling-stage concentrated biogas slurry foliar fertilizer in transplanting cotton. Background technique [0002] The two-crop planting system in farmland can effectively use light and temperature resources, increase the multiple cropping index, and significantly improve the annual economic benefits. Transplanting cotton after wheat / oil / garlic has been popularized and applied on a large scale as the main planting method of double-cropping cotton fields in the Yangtze River Basin and the Yellow River Basin. Please see: Mao Shuchun. Chinese Cotton Cultivation [M]. Shanghai Science and Technology Press, 2013. However, there are serious problems such as slow seedlings, late emergence and late maturity of transplanted cotton. Pleas...
