Abstract
The invention relates to a fertilization technology, in particular to a precision simplified high efficiency fertilizing method for rice. The method comprises the following steps: before rice soaking, spreading all fertilizers as base fertilizers uniformly over the fields, combining with rotary tillage to mix the fertilizers in an arable layer for 7-10 cm, then carrying out rice soaking, pulling plates and leveling, with no need of dressing additional fertilizers in the whole growth period; or using 65-80 wt% of inorganic nitrogenous fertilizer and all phosphorus potassium fertilizers as base fertilizers, uniformly spreading the base fertilizers over the fields, combining with rotary tillage to mix the fertilizers in an arable layer for 7-10 cm, and topdressing all residual inorganic nitrogenous fertilizer in the last phase of tillering or the early stage of booting, with no need of dressing additional fertilizers in the whole growth period. The method disclosed in the invention can satisfy the nutrient requirements of rice in the whole growth period, specially can guarantee the nutrient supply in the early stage of rice, with the characteristics of simpleness and labor saving, and can effectively improve the fertilizer efficiency, reduce agricultural production cost and the like.
Description
Technical field
The present invention relates to fertilizer practice, the rice high efficient fertilizing method that specifically a kind of smart amount is simplified.
Background technology
Paddy rice is one of topmost cereal crops in the world, and it is staple food with rice that 1/2 population is arranged approximately.The present paddy rice in Liaoning Province is planted about more than 900 ten thousand mu, and rice is as the staple food kind, is guaranteeing China's grain security, is improving and have very important effect in resident's trophic structure.Scientific and reasonable fertilizer practice is an important step of rice high yield, efficient cultivation management technology.At present, also there are many problems in fertilizer practice in the our province Rice Production process, such as not accomplishing rational balance fertilizing, lack reasonably scientific and technical the guidance and carry out the fertilising of essence amount and in good time fertilising or the like, cause fertilizer and artificial unnecessary waste, increase peasant's production cost, influenced output and the problem such as low in economic efficiency of paddy rice.
Summary of the invention
The rice high efficient fertilizing method that the object of the present invention is to provide a kind of smart amount to simplify.
For achieving the above object, the technical solution used in the present invention is: before the soaked field, rice field, all fertilizer are evenly spread fertilizer over the fields the field face and in conjunction with rotary tillage fertilizer sneaked into topsoil 7～10cm as base manure, soaked field, arm-tie leveling then, whole growing does not need to impose any fertilizer again;
Or with the inorganic nitrogeneous fertilizer of mass percent 65-80% and all phosphorus potash fertilizer as base manure, evenly spread fertilizer over the fields the field face and fertilizer is sneaked into topsoil 7～10cm with rotary tillage, remaining inorganic nitrogeneous fertilizer will all impose in earlier stage in late tillering state or booting, and whole growing does not need to impose any fertilizer again.Wherein, nitrogenous fertilizer can be common urea or slow-release carbamide; Phosphate fertilizer can be diammonium phosphate, and potash fertilizer can be potassium chloride or potassium sulphate.
The present invention has following advantage:
1. has solid scientific basis.The present invention is a foundation with paddy rice regulation of fertilizer requirement, the fertile characteristic of suction, to survey on the basis that native technique of balanced fertilizer is means, propose in conjunction with local climatic characteristic, soil characteristics and rice nutrient demand rule, the rice high efficient fertilizing method that provides smart amount to simplify, the inventive method is simpler and easy, saving of labor, effective, the manpower and financial resources waste of avoiding topdressing and being brought.
2. application effect is good, reduces production costs.The fertilizing method that the present invention adopts reduces fertilizer application frequency, and saving of work and time saves money again, is applicable to the Rice Production under the various cultivation modes, and every mu can be improved output in (with the conventional fertilizer application result as benchmark) more than 5%.
The inventive method can satisfy paddy rice in whole growing to nutrient demand, particularly can guarantee nutrient supply in paddy rice early stage, have characteristics simple and easy, the saving of labor, can effectively improve utilization rate of fertilizer and reduce effect such as agriculture production cost.
