The invention discloses an agent for controlling excessive vegetative growth and strengthening seedlings of peanuts and a preparation method and an application of the agent. By taking silicate, mepiquat chloride and uniconazole as effective components, 1-10% of silicate, 10-50% of mepiquat chloride, 0.1-5% of uniconazole and 1-50% of an assistant and soluble filler are evenly mixed and ground to obtain the agent for controlling excessive vegetative growth and strengthening seedlings of peanuts; and by utilizing the stress resistance of the silicate and the characteristic of coordinated nutrient utilization, the absorption and the utilization of elements such as N, P and K in soil caused by peanut root systems are promoted, the capability of photosynthesis of the peanut is enhanced, the problems of excessive vegetative growth and lodging of aboveground parts are effectively controlled by matching with the mepiquat chloride and the uniconazole for adjusting the development process of the peanut, the seed setting rate and the grain plumpness rate of the peanut are increased, and the problems of soil nutrient deficiencies and excessive vegetative growth and lodging of the peanut in the south region of China are effectively solved. The prepared agent for controlling excessive vegetative growth and strengthening seedlings of peanuts can effectively improve the stress resistance of the peanut, has a good yield-increasing effect, and is simple in production process, simple and convenient in using method, and easy to popularize and apply.

The invention discloses a peanut seed-dressing agent as well as a preparation method and an application thereof. The peanut seed-dressing agent comprises sodium silicate, calcium nitrate and a plant growth regulator, wherein the plant growth regulator can be one or a mixture of any of an indolebutyric acid, a naphthylacetic acid and a brassinolide. The peanut seed-dressing agent has the capacity of effectively lightening aluminum stress on peanuts so as to promote the growth of roots and strengthen seedlings. The production process of the peanut seed-dressing agent is simple; and the application method of the peanut seed-dressing agent is simple and convenient. Thus, peanut seed-dressing agent is easy to popularize and apply.

The invention relates to the field of agricultural planting, in particular to a method for planting corn in dry land by shallow and rotary micro furrow covering, and solves the problem that straw returning-to-field rate is lowered due to incomplete seedling emergence of conservation tillage adopted in current corn sowing. The method includes the following steps: a, smashing straw to the length less than 10cm in autumn prior to covering the land surface with the straw, subsoiling once every two years with the subsoiling depth of 30-40cm, then performing rotary tillage with the depth of 5cm, and enabling the smashed straw to be mixed with surface soil; b, discharging the straw to two sides of each furrow when furrowing in spring, compacting ridge soil on two sides of each furrow with the depth of 5-15cm, and sowing seeds in wet soil parts of the furrows; performing preemergence herbicide spraying. By the method, water-holding capacity of soil is improved obviously, the seeds can absorb soil moisture beneficially, survival rate of emerged seedlings is increased, the method has the advantages of being scientific and reasonable and convenient to operate, and crop yield per unit is increased effectively.

The invention relates to a chemical control preparation for enhancing the stress resistance and the seed yield of wheats and application thereof, in particular to a chemical regulation preparation for enhancing the low temperature resistance, the lodging resistance, the drought resistance and the seed yield of the wheats and application thereof, belonging to the technical field of crop growth and regulation. The chemical control preparation for enhancing the stress resistance and the seed yield of the wheats comprises the following compositions per kilogram: 0.02-0.06g of auxin, 0.8-1.2g of fluroxypyr, 1ml of surfactant, 1ml of non-protonation polar solvent and the balance of water. The chemical control preparation provided by the invention can control vigorous growth before winter and invalid tillering amount of crops above the ground part, save the nutrients, promote root downward growth, enable stem bases of most wheats to be vertical or approximately vertical to the ground and enhance the winter and prevernal freezing damage resistance and cold damage resistance of plants when enhancing the drought resistance of the plants.

The invention discloses a special fertilizer for the integration of water and fertilizer for corn and an application method thereof. The special fertilizer for the integration of water and fertilizer includes a special fertilizer for emergence, a special fertilizer for the ear stage, and a special fertilizer for the flowering and grain stage; the three special fertilizers all include the following components: Urea, diammonium phosphate, potassium chloride, zinc chelate, boric acid, manganese chelate, magnesium chelate, iron chelate, copper chelate. The special fertilizer for the integration of water and fertilizer for corn of the present invention is developed according to the demand law of corn for nutrients, adopts different fertilizer formulas in different growth stages of corn, and has strong pertinence; the ratio of nitrogen, phosphorus and potassium is reasonable, and meets the requirement of large amounts of nutrients in different growth and development stages of corn. At the same time, adding trace elements can play a role in balanced fertilization, higher fertilizer utilization efficiency, and can significantly increase corn yields to achieve the purpose of increasing production and income; all nutrients are quick-acting nutrients, good water solubility, stable properties, and drip irrigation Combined with the method, the dripper will not be blocked during the drip irrigation process, has the advantages of saving fertilizer and water, and is suitable for popularization and application.

The invention relates to a combined rotational tillage method capable of harvesting high-yield wheat and corn twice and improving the organic carbon content. The combined rotational tillage method capable of harvesting the high-yield wheat and corn twice and improving the organic carbon content comprises the steps that (1) corn straw is crushed and fully returned to a field for subsoiling after summer corn is harvested, and before summer corn is sowed in the next year, the field is covered with wheat straw for returning, the corn can be planted without any tillage; (2) in a next crop rotation period, before winter wheat is sowed and after the summer corn is harvested, the corn straw is crushed and returned to the field, and deep rotary tillage is conducted directly; before the summer corn is sowed in the next year, subsoiling is conducted after the field is covered with the wheat straw for returning; a pattern of the tillage is that subsoiling and rotary tillage are combined in a wheat season, no tillage is in a corn season; in the next year, the rotary tillage is conducted in the wheat season, subsoiling is conducted in the corn season, and the above tillage modes are carried out in turn very other year. The combined rotational tillage method capable of harvesting the high-yield wheat and corn twice and improving the organic carbon content can be completed within two crop rotation cycles (two years), the tillage frequency is reduced, costs are saved, the number of times of disturbance of topsoil is reduced, a good soil aggregate structure is maintained, and meanwhile the organic carbon content in the topsoil of 0-30 cm thick can be significantly increased by 0.36 g / kg; in addition, the yield of wheat and corn is significantly increased.

The invention relates to method for cultivating three-stem cotton. The technology is characterized by comprising the following steps: shooting growing points on the main stem of a cotton plant after 5 to 6 main leaves growing on the cotton plant are spread; and reshaping the cotton plant when three vegetative shoots over 5cm grow from the axil of the main leaves, removing other residual vegetative shoots, and keeping the three vegetative shoots with similar sizes to become three main stems, secondarily shooting tops of the three main stems and local conventionally cultured spring cotton which is subject to top shooting in the same term. The technology has the advantages of saving man power for management, increasing photosynthesis of the plant, improving the fiber quality, reducing amount of boll rot, increasing the amount of canicular boll, and improving the cotton yield.
