Composition for preventing and treating fruit-cracking disease, sunscald and navel orange yellowing disease of crop fruits as well as preparation method thereof

The invention discloses a combination for prevention and cure of the disease of dehiscent fruit, sunscorch and yellow-navel disease. The combination is prepared with raw materials with the following weight percentage: 0.5-0.7 percent of EDDHA-Fe, 0.7-1.3 percent of EDTA zinc-titanium, 3.0-4.2 percent of EDTA manganese-titanium, 1.0-1.5 percent of EDTA calcium- titanium, 2.5-3.5 percent of high polymerized sulfonated naphthalene formaldehyde, 0.3-0.7 percent of EDTA titanium and 88-92 percent of deionized water. The invention has the advantages of that: 1) after the product is sprayed on the crops, the flexibility and expansion strength of the fruit skin can be improved, and the phenomenon of dehiscent fruit due to the poor flexibility of the fruit skin is avoided; besides, the effective constituents of the invention carry large quantity of moisture to penetrate from the foliages toward the fruits rapidly supplement the fruit moisture, and as a result, sunscorch is avoided; 2) the product is capable to enhance the adverse-resisting property of the plant, increase the anti-disease capability so that to achieve the effects of prevention and cure of dehiscent fruit, sunscorch and yellow-navel; 3) the invention is capable to improve the activity of microelements and enhance the microelement absorbing capacity of the plant.

Method for synthesizing EDTA (ethylene diamine tetraacetic acid) calcium sodium salt hydrate by low molecular alcohol precipitation at low boiling point

The invention discloses a method for synthesizing EDTA (ethylene diamine tetraacetic acid) calcium sodium salt hydrate by low molecular alcohol precipitation at a low boiling point. The method mainlycomprises the following steps: adding EDTA disodium and calcium salt in hot desalinized water; and adding alcohol, standing and filtering to obtain the EDTA calcium sodium salt product. The EDTA calcium sodium salt hydrate is prepared by the method, a high-temperature and high-pressure process does not exist, required equipment and process are simple, and the investment risk is small. Compared with a traditional process, the process has the advantages that a concentrate process does not exist, and effects of energy conservation and emission reduction are obvious. The product is obtained by a liberation method, and thus, the product is uniform in granularity and excellent in quality. Meanwhile, alcohol which is rectified and recycled in the method can serve as recycled alcohol and is used as a precipitation agent for an experiment in next time, remaining water is used as a solvent for the experiment in next time, wastes are not discharged in a whole technological process, and the benefit of environmental protection is high.
