Problems solved by technology

However, blindly increasing the amount of fertilizer will not only increase the production cost, but also destroy the soil structure and cause the deterioration of the ecological environment. The more the amount of fertilizer is increased, the worse the soil will be, which will lead to a vicious circle

Embodiment 1

[0025] Contrast test: In order to illustrate that the rice fertilization method of the present application is better than the traditional method, the applicant has done a comparative test. The test is to compare the application's three fertilization methods (3 times of fertilization throughout the growth period) with the traditional five fertilization methods (fertilization of the whole growth period) A total of 5 times) were compared on the impact of rice yield, specifically as follows:

[0026] Test site: Longping Hi-Tech Base, Wucai Garden, Yulin City, Guangxi.

[0027] Test year: Early build in 2016.

[0028] Rice variety planted: Toyota You 553

[0029] Basic nutrients in the test field: organic matter 1.36%, total nitrogen 1.62g / kg, total phosphorus 12.1g / kg, total potassium 10.35g / kg.

[0030] Test plan: The test set up 6 treatments and 3 repetitions, namely: CK, A, B, C, D, E treatments, among which,

[0031] CK: no fertilization;

[0032] A treatment: traditional ...

Abstract

The invention discloses a fertilizing method for realizing high rice yield and relates to the technical field of agricultural planting. The method comprises the following steps: three times of fertilization of base fertilizer, additional fertilizer and panicle final fertilizer are applied in the whole growth period of the rice, the total amount ratio of nitrogen, phosphorus and potassium in threetimes of fertilization is 1:0.63:1.04, the total nitrogen amount for three times of fertilization is 20.90 kg/mu, total phosphorus amount for three times of fertilization is 13.25 kg/mu, and total potassium amount for three times of fertilization is 21.75 kg/mu. The fertilizing method, use amount and proportion are improved according to fertilizer demanding and absorbing rules of the rice in different growth periods, land utilization and land maintenance are combined, fertilizing times are reduced to 3 times from the traditional 4-5 times, fertilizing amount and proportion of nitrogen, phosphorus and potassium are quantified and reasonable, fertilizing periods are clear, so that production cost is reduced, and yield is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of agricultural planting, in particular to a high-yield fertilization method for rice. 【Background technique】 [0002] Rice yield is affected by many factors, among which scientific and reasonable fertilization has the best effect on increasing yield and continuous yield increase. Only by grasping the reasonable timing of fertilization and the appropriate ratio of dosage can we achieve continuous high yield, stable yield and significant increase in yield year after year. [0003] At present, the rice fertilization method is mainly as follows: according to the four growth stages of rice seedling stage, tillering stage, ear stage and fruiting stage, the fertilization period is divided into four periods: base fertilizer, tillering fertilizer, ear fertilizer and grain fertilizer, that is, base fertilizer is applied during soil preparation, Apply tiller fertilizer about two weeks after transplanting, apply ear ...
