Chapter 1697 Act immediately
"My original intention was to make Renzhong cry for poverty and put some pressure on the experts. Even if the cherry base does not stay with us, at least we can keep the Moroccan pomegranates." Wait until the expert group leaves. Later, Zhou Zhi reflected deeply in the conference room: "I really didn't expect Grandma Liu to be so upright and leave the cherry base with us."
"Ahem..." Lao Chiri respected the experts very much and reminded Zhou Zhi: "Liu The professor said that they are called American cherries, those from abroad are called Brooks, and those from China are The hybrid is called Hongdeng No. 1..."
"The old man remembers it quite clearly..." Zhou Zhi said: "But this is not the focus of our discussion now. The focus is on the fertilizer requirements of cherries. A little high, just like the suckling pigs in Jiukou Township, Things are good, but we also have to consider whether we can afford them."
"This state must consider it, right?" Wu Ren Center also had no idea: "We really want to make it a country. project, then it’s not our turn to be interested, right?”
“It’s not a big problem if the state gets some chemical fertilizers, but farm compost is probably going to be too much,” Zhou Zhi said, “But Professor Liu said, farm compost is more important for cherry planting. A tree needs about 40 kilograms of compost a year. In addition to being used as fertilizer, it also regulates soil pH and prevents compaction. "It is also very important to improve the soil structure here and increase organic matter," Wu Renzhong added.
"Elbow, how was it solved in your hometown?" Lao Chiri now knew that Zhou Zhi was quite familiar with farming, so he asked.
“This is totally incomparable.” Zhou Zhi was dumbfounded: “Our fields have been left uncultivated for a year, and the grass has grown half as high as a man, and is so dense that even our feet can’t reach in.”
“If We can’t use up the black oats we grow, it would be great if we could turn half of them into the fields..." Wu Renzhong sighed.
"Huh?" Zhou Zhi suddenly thought of a question and slapped his forehead: "The autonomous prefecture is an important cattle and sheep producing area in Sichuan!"
"What happened to the cattle and sheep producing area?" Wu Renzhong did not react.
“Since it is a cattle and sheep production area, the state Academy of Agricultural Sciences must have systematically collected and researched local forage. There may be many major grain-growing counties that have already been promoting types of forage that can be used as both grazing and fertilizer. Let’s let the state give us an idea!”
Wu Ren Zhong suddenly became angry: "I just said that we should rely on the state. You said that the state is unreliable, and now you have changed your tune?!"
"Did you mean this just now... Forget it, let's go first!" Just ask, if it is true, we don’t need to waste our brains.”
Now the phone line has been opened. People from the State Academy of Agricultural Sciences came to investigate the feasibility of the pomegranate base in advance. They were given the "inspection fee" of half a year's salary by Zhou Zhi. The relationship was well-established. After a phone call, the answer was very clear. Be back soon.
“Yam, what are you talking about?” Zhou Zhi didn’t know what Wu Renzhong was talking about in the feedback from the Academy of Agricultural Sciences: “Is it a sweet potato with leaves or a yam with a base? We have a kind of yam with a leaf called a yam with a base. , Some people call that stuff wild peas.”
“No, our wild peas are wild peas,” Lao Chiri corrected.
"Hey! Just in case there is a magpie's nest, Qiong will have a lucky star!" Zhou Zhi suddenly understood.
Wild peas are a character that often appears in the Book of Songs. They have several names. For example, when they are still tender in spring, they are called "Wei". Boyi Shuqi, who was a shameful eater of Zhou millet, ate this stuff to satisfy his hunger. , and finally starved to death on Shouyang Mountain.
In addition, in Chen Feng's poem, wild peas are called "蕕". This name was used by the Shu people until the Song Dynasty. Su Dongpo said that in order to commemorate Chaogu, the field peas were called "Chaocai". The pronunciation of the word "蕕Chao" is similar, and Zhou Zhi didn't know until today that "蕕", the ancient name for wild peas, has actually been retained in Liangshan Prefecture.
"What's the expression on your elbow?" Tu Liangzhi couldn't help but laugh when he saw Zhou Zhi's overjoyed look.
“I’ve become more knowledgeable again,” Zhou Zhi said with a smile: “This word was originally used thousands of years ago. I always thought it was useless at least a few hundred years ago, but I didn’t expect that it is still used here. .”
“That’s what the elbow is like.” Lao Chiri praised: “I’m very considerate of this aspect.”
After learning more about it, Zhou Zhi realized that the pasture in the autonomous prefecture was a perennial twining herb, belonging to the Fabaceae family and the genus Vaccinia. It grew in alpine shrubs, streams and valleys with an altitude of more than 1,000 meters. It is a unique variety in northern Yunnan and southern Sichuan.
After the autonomous prefecture crossed it with a high-quality pasture of the same genus in the Jiangnan area called "Jiangtong Yaozi", it got a kind of grass that is adapted to local growth, resistant to diseases and frost, drought-tolerant but not water-resistant, and is good for soil Excellent forage with very low requirements but relatively high yield.
This kind of pasture can absorb nitrogen from the air and transfer it to the soil, which has the effect of replenishing nitrogen to the soil. It is also an excellent pasture with a very high protein content and can be used as feed for livestock. , it can also be used as green manure and turned under the soil to become farm green manure.
The only drawback is that during the flowering and fruiting stages, this grass is slightly toxic, and livestock may have toxic reactions if they eat too much.
People from the Academy of Agricultural Sciences said the solution is very simple, that is, harvest the wild rice in time, before it blooms, and then store it in special cellars or store it as hay, which can be used as winter grain for livestock.
The remaining pile heads are allowed to grow in the ground for two crops, bloom and bear fruit, and are finally turned into the ground to make green manure.
The reason why the autonomous region wants to promote this kind of pasture also plays a very important role-maintaining water and soil.
This function is also very much needed in Lianhe Township. Although the yield of wild rice is not as high as that of ryegrass, its root system is much more developed than that of ryegrass, and it has a better effect on soil and water conservation.
The potatoes grown by the Yi people must be rotated, and after the corn is harvested, the hillsides become barren, and this period becomes the "land fallow period."
There are two ways to let the land go through the fallow period. One is called plowing and fallowing, which is to turn the weeds on the fallow land into the ground through continuous plowing to prevent the weeds from growing too vigorously. , sucking away nutrients from the land and affecting next year’s harvest.
There is also a newly launched and very practical method, which is green manure fallowing. Green manure crops are sown during the land fallow period. When the green manure crops grow to a certain stage, farming measures are used to bury all the green manure plants into the soil layer. To achieve the purpose of increasing soil organic matter, absorbing and storing precipitation, and improving soil fertility. This is Green Manure Leisure.
This is originally an agricultural technology used in the northern region to solve the problem of "summer stubble land" fallow. It has been tried to be implemented in some areas for many years. However, in the country of Tianfu in the middle of Sichuan, this technology is basically not available, so it is not As for how to attach importance to it, it was only recently that the autonomous prefecture felt that it could be used to solve the problems of soil improvement in barren mountainous areas and soil and water conservation in fallow lands.
Understanding again, before the rainy season comes, it is a good time to plant this. Seedlings will emerge after the first rain and quickly become lush and green.
We can’t wait any longer, we must take action immediately, because the rainy season is coming soon.
