The invention relates to a cotton and peanut intercropping and crop rotation efficient planting mode in medium and slight sulfate saline-alkali soil. The cotton and peanut intercropping and crop rotation efficient planting mode in medium and slight sulfate saline-alkali soil comprises the following steps: in the current year, carrying out cotton and peanut wide-range strap-shaped intercropping on the medium and slight sulfate saline-alkali soil according to a 4: 6 (ridge: ridge) mode, fully playing edge advantages of high-salt-tolerance cotton firstly, and remarkably increasing optical energy utilization rate; secondly, by difference between growing speeds of the two crops, reducing the wind speed of a field in the spring, reducing water evaporation and diffusion of soil, and relieving saline-alkali damage; thirdly, improving soil fertility by nitrogen fixation of peanut root nodules, spraying nitrogen to crushed straws and returning the straws to the field so that a soil structure can be improved and organic matters can be increased; in the next year, interchanging cotton planting zones and peanut planting zones, and carrying out intersected crop rotation on the planting zones, wherein the width of the cotton in the field is consistent to the width of the peanut in the field, and continuous cropping obstacles are relieved effectively. By intercropping in a year and crop rotation in two different years, efficient production of cotton and peanuts is realized, land use and land nourishing are combined, and therefore, the cotton and peanut intercropping and crop rotation efficient planting mode in medium and slight sulfate saline-alkali soil has a special important practical significance on propelling of regional economy and social and ecological sustainable development.

The invention discloses high tower seaweed nitrate-sulfate base compound fertilizer, which is prepared from the following raw materials in parts by weight: 15-20 parts of phosphorus nitrate, 10-15 parts of monoammonium phosphate, 20-25 parts of potassium sulfate, 30-35 parts of a seaweed extract and 20-30 parts of seaweed residue. The high tower seaweed nitrate-sulfate base compound fertilizer isprepared by compounding seaweed, so that the better fertilizer efficiency is realized by applying the fertilizer once by a user, and the crop growth rate is increased.

The invention discloses a method for carrying out fertilizer application at a vegetative growth phase in accordance with the change of a crop plant height. The method comprises the following steps: firstly, establishing a fertilizer application amount standard table according to the growth day number, the plant height, the plant height daily change and fertilizer application amounts after crops in a standard plant sample region at the vegetative growth phase are planted, and then measuring the crop height and the plant height daily change at the vegetative growth phase in a region to be subjected to the fertilizer application; and calculating the crop plant height, the projection area daily change value and the fertilizer application amounts of the crops with the same growth day number, which are planted in the fertilizer application amount standard table of the standard plant sample region, according to a certain rule, so as to obtain the intraday fertilizer application amount of the crops. The method disclosed by the invention can be used for a modern agriculture precision irrigation and fertilizer application field and is good for controlling the growth speed of the crops, improving the utilization rate of fertilizers, reducing agricultural non-point source pollution and the dependency on a user knowledge level of crop fertilizer application management and reliving the labor intensity; the method can be used for guiding the fertilizer application of greenhouse cultivated crops at the vegetative growth phase.

The present invention discloses a food crop yield increase nutrition agent, which comprises, by weight, 3-8 parts of a nitrogen fertilizer, 1-4 parts of a potassium fertilizer, 2-6 parts of a phosphorus fertilizer, 2-8 parts of enzyme, 2-8 parts of phosphorus bacteria, 1-4 parts of silicate bacteria, 2-3 parts of chitin, 1-3 parts of amino acids, 0.2-0.5 part of gibberellin, 0.2-0.5 part of indole acetic acid, and 0.3-0.5 part of azotobacter. According to the present invention, the food crop yield increase nutrition agent contains balanced nutrients, provides good adjustment effects for physiological and chemical reactions of food crops, can accelerate uptake of crop roots on nutrients and accelerate cell division so as to increase crop growth rate, is a natural bactericidal agent, and has strong insect pest resistance.

The invention discloses a bio-organic fertilizer. The bio-organic fertilizer is characterized in that livestock excrement, cornstalks, peanut shells, cottonseed shells, high-quality activated lactobacillus plantarum, an EM bacterial agent and bacillus megaterium are used as raw materials, and the raw materials including the livestock excrement, the cornstalks, the peanut shells, the cottonseed shells, the high-quality activated lactobacillus plantarum, the EM bacterial agent and the bacillus megaterium are weighed in parts by weight. The bio-organic fertilizer contains organic matters, activated microbial flora, humic acid, medium trace elements of magnesium, calcium, boron, zinc and copper and the like which are needed by plant growing and soil improvement, the disease resistance, diseaseprevention and cold resistance of crops, flowers and fruit trees can be effectively enhanced, the growing speed of the crops is improved, plants are robust, and the fruit bearing rate and the yield are improved.
