What makes the experts special

Section 3 Chapter 18 Cutting Leaves Like a Song / Nanfan Chronicle

Although there was not much problem, when the young panicle development entered the fifth or sixth stage, there were still individual fields with varying degrees of flowering deviation.

According to the instructions of Director Ji, Ma Linxi and Wang Changsong took samples for testing, and found that the female parent was still early, and the full flowering period was about four days earlier than the male parent.

"How many samples did you take?" asked Deputy County Magistrate Yang looking at their flowering forecast table, his expression serious, obviously, he was also anxious. Although there are only two fields, less than 10 acres, if there is no harvest, it will be difficult to make up the balance by other fields.

"Where are the peeled spikes?" Deputy Director Ji Xuebin took the flowering forecast table and looked at it for a long time, then raised his head and asked.

"It's in the dormitory. Malinsi said. I thought to myself, is there any doubt about this? I don't have to peel the young ears in Marinsy for a day or two.

"Go get it. Deputy Director Ji said decisively.

Wang Changsong quickly put the young ears with small white paper plates on the table, and placed them neatly according to the order of field sampling, with the head of the rice ear on the left and the number plate on the right.

At this time, Zhang Dayou, a breeding technician from the County Agricultural Science Institute, stepped in. This time, he and Xu Feng were mainly responsible for the small rice varieties of the county agricultural science institute, and they did not directly inquire about the technology of seed production.

Deputy Director Ji and Deputy County Magistrate Yang checked the progress of the young spike development image of each tree one by one against the observation results recorded on the flowering forecast table, and finally asked Zhang Dayou to use an abacus to recount.

As a result, there was little difference between the data checked by the leaders and the data provided by Marinthi. Then, if it is accurate, it is necessary to take adjustment measures to quickly delay the development of young spikes of the female parent and promote the differentiation of young spikes of the male parent.

"Lao Ji, you are an expert, let's see what to do next?" Deputy County Magistrate Yang Hongru was a little undecided.

"Let's go. Let's go to the fields and talk about it. What do you see?" Deputy Director Ji Xuebin asked Deputy County Changzheng Yang on the side.

"Okay. There you go. I have to go to Banpo to find Secretary Zhang of the Lower Commune, and then implement the matter of going into the water. Deputy County Magistrate Yang took a draft hat and walked towards the door.

Ma Linxi and the three of them followed behind Deputy Director Ji and came to Tiantou.

"How did you get the sample?" Deputy Director Ji pushed the brim of his straw hat up.

"Take a point from each of the four corners, and a point in the middle. Marlinsi replied.

Deputy Director Ji didn't reply, cut his hands back, and walked thoughtfully along the ridge.

The field was not large, and after walking around the edge of the field, he turned around and walked half a circle again, looking a little thoughtful. Then he took off his sandals and walked barefoot to the middle of the field. Walk for a section and take the main stem of a seedling.

Unlike Marlinthi, he took more than 20 points from his 50 samples, that is, the samples were more dispersed and more representative.

In the case of water and fertilizer conditions and seedling growth are basically the same, there is no need to take so many points. Five points, fifty samples are enough. Marlinsi thought to herself. However, Deputy Director Ji is after all a rice expert from a professional class, and he is a national-level rice cultivation expert, and if it were not for the temporary variables that have occurred in international relations, he would now be directing the cultivation of rice in Tanzania on behalf of China.

Deputy Director Ji put the samples he had taken personally on the ridges, and several people gathered around and peeled them off. Then Deputy Director Ji judged the progress of the young spike differentiation one by one, and Ma Linxi held a notebook and recorded them one by one in a special form.

The final statistical results are two days shorter than Marlinsi's data, i.e. the flowering period of the male parent is two to three days apart.

So, where is the error between Ma Linxi's statistics and Deputy Director Ji's statistics?

Before they could speak, Deputy Director Ji spoke first: "Have you seen the seedlings at the water inlet? This is pure sandy soil, if it is irrigated within 24 hours after fertilization, the fertilizer is not absorbed by the soil and rice roots, and it is easy to wash away with the water when the seedling field is watered, forming a fan-shaped fertilizer deficiency area. When you look at the southeastern part, do you notice that the fields are low, the seedlings are deeply irrigated, and the shade of the north-south highway to the east and the east-west highway to the south is particularly large.

"Where there is a shortage of fertilizer, young spikes develop quickly. Where there is sufficient fertilizer and water, and there is a lack of sunlight, the development of seedlings will of course be slower. Isn't that right?" Deputy Director Ji patiently analyzed with them.

Ma Linxi and the chickens kept nodding their heads like eating rice, and they admired the specific application of Deputy Director Ji's cultivation theory in production practice.

Deputy Director Ji did not blame them, but kindly reminded them, telling them that mastering rice seed production technology is the same as dealing with other problems, and that they should be good at using their brains and proceeding from reality. Crop cultivation is never yielding high yields without the situation of specific plots. Factors such as microclimate and fertility, moisture, pests and diseases in the same field will affect the accurate assessment of the overall cultivation and fertility status.

The deeper reason lies in the fact that although Ma Linxi is an ordinary breeder here, when he returns to his hometown, he is in charge of the technical department of the command side, and at least he directs the rice seed production and cultivation technology of thousands of mu of rice in a production brigade, and he directs the crop cultivation technology of tens of thousands of mu in a commune. In addition to the direct task of hybrid rice seed production, Nan Breeding also has the task of training the county's rice cultivation technology elites.

According to the results of the re-prediction, they applied urea fertilizer to the female parent in the area of fertilizer shortage in the water inlet area to delay the rapid development of young spikes. For the deep water area in the southeast corner, a ridge is specially set up to drain all the water in it, so as to have the effect of resting the field and breathing and promote the development of its young spikes.

Through the implementation of these two measures, when the heading begins, the flowering period of this field basically meets. In addition, there are a few plots of land that have slightly deviated from the flowering period, and they have taken measures such as shelving the fields. One of the fields was laid aside, and the root of the female parent was also cut.

The so-called root cutting is to cut two or three shovels horizontally around the seedlings with a shovel after the water is drained, and cut off part of the root system of the transverse growth, so that it can absorb nutrients and water from the soil and be seriously affected, so as to appropriately delay the development of its young spikes.
