A special formula fertilizer for rice cultivation

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...

Embodiment 1

[0128] In the field experiment of 60 mu in Jiangsu and Zhejiang areas, the Yongyou 12 variety was used, and three repetitions were set. Under the premise of not using the base fertilizer, the special fertilizer a for rice was topdressed for the first time within 5 to 7 days after transplanting, and the amount of fertilizer was 10kg / mu; the second top dressing is carried out one month after transplanting, and the amount of fertilizer is 20kg / mu; the third topdressing is carried out two months after transplanting, and the amount of fertilizer is 5kg / mu; the total amount is 35kg / mu.

[0129] The specific top dressing method: it can be evenly spread in the paddy field manually, or the fertilizer a) above can be dissolved in clear water according to the water addition amount of 50 times the mass ratio, and sprayed directly in the paddy field through sprinkler irrigation or micro-spray equipment; After dissolving the fertilizer in the clear water directly in the field, it is applied ...
