Embodiment 1

[0128] In the 60-mu field experiment conducted in Jiangsu and Zhejiang, the variety Yongyou 12 was used and repeated three times. On the premise of not using the base fertilizer, the special fertilizer a for rice was used for the first topdressing within 5 to 7 days after transplanting. The amount of fertilizer applied was 10kg / mu; the second topdressing one month after transplanting, the fertilization rate is 20kg / mu; the third topdressing is carried out two months after transplanting, the fertilization rate is 5kg / mu; a total of 35kg / mu.

[0129] Concrete method of topdressing fertilizer: it can be evenly sprinkled in the paddy field artificially, and the above-mentioned a) fertilizer can also be dissolved in clear water according to the water addition of 50 times the mass ratio, and directly sprayed in the paddy field by sprinkling irrigation or micro-spraying equipment; In the field, the fertilizer is directly dissolved in clear water, and then applied to the paddy field al...

[0131] In the 60-mu field experiment conducted in Jiangsu and Zhejiang, the variety Yongyou 12 was used and repeated three times. On the premise of not using the base fertilizer, the special fertilizer a for rice was used for the first topdressing within 5 to 7 days after transplanting. The amount of fertilizer applied was 12kg / mu; carry out the second topdressing one month after transplanting, and the fertilization rate is 22kg / mu; carry out the third topdressing two months after transplanting, and the fertilization rate is 6kg / mu; a total of 40kg / mu.

[0132] Concrete method of topdressing fertilizer: it can be evenly sprinkled in the paddy field artificially, and the above-mentioned a) fertilizer can also be dissolved in clear water according to the water addition of 50 times the mass ratio, and directly sprayed in the paddy field by sprinkling irrigation or micro-spraying equipment; After the fertilizer is dissolved in clear water directly in the field, it is applied to the...

Embodiment 3

[0134] In the 60-mu field experiment conducted in Jiangsu and Zhejiang, the Yongyou 12 variety was used and repeated three times. On the premise of not using the base fertilizer, the special fertilizer a for rice was used for the first topdressing within 5 to 7 days after transplanting. The amount of fertilizer applied was 14kg / mu; the second topdressing was carried out one month after transplanting, and the fertilization rate was 23kg / mu; the third topdressing was carried out two months after transplanting, and the fertilization rate was 8kg / mu; a total of 45kg / mu.

[0135]Concrete method of topdressing fertilizer: it can be evenly sprinkled in the paddy field artificially, and the above-mentioned a) fertilizer can also be dissolved in clear water according to the water addition of 50 times the mass ratio, and directly sprayed in the paddy field by sprinkling irrigation or micro-spraying equipment; After the fertilizer is dissolved in clear water directly in the field, it is a...

Abstract

The invention discloses a special formula fertilizer for rice cultivation. The formula fertilizer provided by the invention comprises the following components: KNO3, KH2PO4 or Ca(H2PO4)2, KCl, MgSO4.7H2O or MgSO4.H2O, Ca(NO3)2.4H2O or Ca(NO3)2, FeSO4.7H2O or FeSO4 and CO(NH2)2. According to the experiments, compared with an existing normal fertilizer application method of a compound fertilizer, urea, ammonium hydrogen carbonate, potassium chloride and a biological fertilizer, the yield per unit area of the special formula fertilizer for rice cultivation provided by the invention is increased; the using method of the special formula fertilizer is simple and convenient; the plants grow healthily, and are resistant to lodging and diseases and pests, the pesticide spraying times are reduced, the pesticide cost and the labor cost are reduced, the yield per unit area can be increased by about 10%, the quality and the mouthfeel of hybrid rice and common japonica rice are improved, the original flavor of the rice is recovered, and the storage resistance of the hybrid rice is improved. The special formula fertilizer has a very wide application value and a very wide market prospect.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a special formula fertilizer for rice cultivation. Background technique [0002] Rice is one of the most important food crops in my country. Its planting range covers a large area of ​​my country from Hainan Island to Heilongjiang, from East China to Sichuan. According to statistics, my country's rice planting area reaches 453 million mu, accounting for about 30% of my country's grain output, and it is a veritable staple food. With the acceleration of industrialization and urbanization, the situation of maintaining arable land area is becoming increasingly severe. The development of industrialization and urbanization requires a large amount of land for construction, which has serious contradictions with maintaining the stability of food production. The increase of construction land will inevitably lead to the decrease of cultivated land. Under the basic premise that the area of ​​c...
