[0003] Although there have been common "fertilizers" for various crops in China, in these fertilizers, because the micronutrient elements have not been treated such as chelation, the activity is poor, and the fertilizer damage is often greater than the fertilizer effect after application; , but due to the improper selection of chelating agents, or the inappropriate proportion of various nutrients, the effect of preventing and controlling rice nematodes and fungi, increasing rice yield or improving rice quality is not ideal.

Embodiment Construction
[0010] Below in conjunction with embodiment the present invention is further described in detail:
[0011] The invention provides a special fertilizer for rice blast resistance rice production increase, said special fertilizer for rice blast resistance rice production increase contains nitrogen in plant nutrient elements calculated as N; 2 o 5 Phosphorus in terms of; in K 2 Potassium in O; middle and trace element additive T after chelation, the proportioning in parts by weight is:
[0012] N:P 2 o 5 : K 2 O:T=1:2:0~5.0:0.429≥T>0.0.
[0013] The chelated medium and trace element additive T is formed by chelating a chelating agent selected from EDDHA, EDPA, HEDTA, DTPA, CDTA, TEA, NTA and EGTA with medium and trace elements.
[0014] The medium and trace elements are from Mg, Ca, SO 4 -2 , Na, Mn, B, Zn, Fe, Cu, Mo, Cl -1 one or more of the selected.
[0015] The medium and trace elements are respectively obtained from the following corresponding compounds:

Abstract
The invention discloses an anti-rice blast special rice yield-increasing fertilizer, which contains nitrogen, in terms of N, in plant nutrient elements; phosphorus, in terms of P2O5; potassium, in terms of K2O; and a chelate medium, trace element additive T, wherein the weight ratio is: N:P2O5:K2O:T=1:2:0-5.0:0.429>=T>0.0. The purpose of the anti-rice blast special rice yield-increasing fertilizer of the invention is to control rice blast, rice false smut and aplelenchiodes bessegi of rice. The beneficial effects of the invention are that the invention provides a safe and nontoxic fertilizer with pesticide functions in agriculture, initiates a precedent for controlling rice soil-borne diseases by compound fertilizers, effectively controls the invasion of rice nematodes and fungi thereof, significantly decreases the incidence of rice blast after the application of the fertilizer, provides a reduction rate of rice blast of up to above 87.5%, allows the field incidence to decrease from 98% to less than 10%; and the yield increasing effect is substantial after the application of the invention.
Description
technical field [0001] The invention relates to a special fertilizer for rice, in particular to a special fertilizer for rice blast resistance to increase production. Background technique [0002] Rice is one of the major food products in the world. Due to the influence of the environment and growth cycle, rice will suffer from a devastating disease, such as rice blast (caused by fungi), flax spot, sheath blight, bacterial blight, bacterial streak, stripe leaf blight, Black-streaked dwarf disease, yellow dwarf disease, rice smut, rice smut, bakanae disease, dry apical nematode and other diseases directly lead to rice discoloration, necrosis, rot, wilting, deformity and even cause plant death, Reduce production, cut production, cut off harvest. In order to prevent rice nematodes and fungi from infesting, the effective measures usually adopted are crop rotation and stubble, and at the same time, highly toxic pesticides are applied for control; in addition to the control of f...
