Abstract

A cultivation method based on the optimization of the amount of a plant nitrogen fertilizer, specifically comprising the following steps: S1, selecting plants to be planted in this batch, and recording the number of the plants to be planted this time, and then preparing different parts of a nitrogen fertilizer for a single plant (10 grams for each part of the nitrogen fertilizer); and S2, the interval being one week, plants of a same batch being planted every Monday, and the time for fertilizing the planted plants being the second week after the plants are planted. According to the cultivation method based on the optimization of the amount of a plant nitrogen fertilizer, by means of more testing and less planting, during estimation of the optimal amount of the fertilizer by staff, and the consumption of plant seedlings is correspondingly reduced, thereby effectively avoiding excessive waste, so that the cost is lower during use by people later, thus bringing help to the whole experiment and making it more convenient for people to use.

Description

A cultivation method based on optimization of plant nitrogen fertilizer application rate

technical field

The invention relates to the technical field of plant planting optimization, in particular to a cultivation method based on the optimization of plant nitrogen fertilizer application.

Background technique

Nitrogen fertilizer refers to a unit fertilizer with nitrogen (N) as the main component and a marked amount of N, which can provide plant nitrogen nutrition when applied to the soil. Nitrogen fertilizer is the fertilizer variety with the largest production and usage of chemical fertilizers in the world; appropriate nitrogen fertilizer dosage is important for improving Crop yield and improving the quality of agricultural products play an important role. Nitrogen fertilizers can be divided into ammonia nitrogen fertilizers, ammonium nitrogen fertilizers, nitrate nitrogen fertilizers, ammonium nitrate nitrogen fertilizers, cyanamide nitrogen fertilizers and amide nitrogen fertilizers according to nitrogen-containing groups. The main production of chemical nitrogen fertilizers The raw material is synthetic ammonia (the Haber method device for generating synthetic ammonia was built in 1909, and it was first industrialized in Germany and became the basis of nitrogen fertilizer industry). In the 1940s and 1950s, ammonium sulfate was the most important nitrogen fertilizer variety; in the 1960s, increasing Ammonium nitrate; since the 1970s, urea has become the leading nitrogen fertilizer variety, and ammonium bicarbonate is one of the main nitrogen fertilizer varieties produced in China in the 1980s.

The existing plant nitrogen fertilizer cultivation method is too complicated, and the calculation time is too long, and does not have the function of timely adjustment. When faced with some large-scale plant planting, more plant seedlings will be wasted to clearly calculate the best planting method , resulting in excessive waste, which is not convenient for people to use and brings trouble to people.

Contents of the invention

(1) Solved technical problems

Aiming at the deficiencies of the prior art, the present invention provides a cultivation method based on the optimization of plant nitrogen fertilizer application rate, which solves the problems raised in the above-mentioned background technology.

(2) Technical solution

In order to achieve the above object, the present invention is achieved through the following technical solutions: a cultivation method based on plant nitrogen fertilizer application rate optimization, specifically comprising the following steps:

S1, select the plants to be planted in this batch, and record the number of plants planted at this time, and prepare different parts of nitrogen fertilizer (every part of nitrogen fertilizer is 10 grams) for a single plant;

S2, the number of days apart is one week, the plants of the same batch are planted every Monday, and the time for fertilizing the plants after planting is the second week after planting;

S3. When plants of the same batch are planted, every 20 plants are used as a group, and there are 5 groups in total in a batch. Apply four parts, five groups apply five parts, and mark;

S4. The growth cycle after planting is four weeks. After the four weeks are over, the first batch of plants will be inspected to detect the best growth conditions, and they will be applied to the fifth batch that needs to be fertilized at this time. After the second batch After the planted plants reach the growth cycle, apply the sixth batch that needs to be fertilized according to the best growth conditions of the new batch, and so on;

S5. One quarter is the entire test cycle. When the whole quarter is over, select various test results, and the group with the most repeated occurrences is the best growth mode, record this mode, and then apply it to the planting of plants.

Preferably, the planting conditions of all groups and batches in S3-S4 are consistent, and the planting conditions are 25°C-30°C.

Preferably, all groups and batches in S3-S4 are planted and watered between 7:00-8:00 in the morning, and the amount of glue each time is 300ml per plant.

(3) Beneficial effects

The invention provides a cultivation method based on the optimization of plant nitrogen fertilizer application rate. Its beneficial effect is that the cultivation method based on the optimization of the amount of nitrogen fertilizer used by plants adopts the method of more tests and less planting, so that when the staff calculates the optimal amount of fertilization, the consumed plant seedlings will be correspondingly reduced, effectively avoiding the Excessive waste, so that the cost of people's subsequent use will be lower, which will help the whole experiment and make people more convenient to use, which is beneficial to people's use.
