Comparatively speaking, Xia Qing had less difficulty in this regard than the other lords. One is because she has less arable land, and the other is because she still has fertilizer in stock.

Her inventory includes 1,500 catties of vermicompost and 500 catties of crab shell fertilizer, as well as chicken and sheep manure fermented by Xia Qing herself, plant ash left over from burning wild grass and cooking, and fermented fertilizer on plant stems and leaves, which are enough for her to grow wheat and rape.

In addition, Sun Zhe said that at the end of this month, Xia Qing would be transported 200 catties of vermicompost to Xia Qing, and Xia Qing also ordered 2,000 catties of crab shell fertilizer from Zhong Tao a few days ago, and today she asked Ji Li about buying fertilizer from the No. 7 territory......

Xia Qing was thinking about it when he received a call from Zhang San.

"Xia Qing, is there a shortage of fertilizer?"

"Yes." Xia Qing told the idol about the destruction of Sun Zhe's vermicompost production line and the increase in fertilizer prices.

Zhang San couldn't trade fertilizer with Xia Qing, "I have special green light fertilizers here, all of them are for breeding, the price is too high, and it is not suitable for you to use them." ”

Xia Qing hurriedly asked, "Third brother, do you have compost fungus powder?" The price of mushroom powder in Territory Nine is getting higher and higher, and it is no longer available. ”

Zhang San didn't understand the situation and asked, "Isn't it two catties of green light vegetables for a bag?"

Although green light vegetables or wild vegetables are sold for about 50 points a catty, it is not difficult for the lords to test and select one or two catties in the territory, so it is not distressing to change the bacterial powder. But now the ninth territory does not agree to exchange with green light vegetables, as long as the points, the price of mushroom powder has risen from 100 to 150, and the last time Qifu exchanged, it rose to 200 points a bag.

Lords need fertilizer for farming, but it's not easy for anyone to earn points. At this price, not to mention the other lords who were not rich in the first place, even Xia Qing couldn't afford it.

Farming continues to require fertilizer, and she has saved enough fertilizer for autumn sowing, but there is still a gap between planting greenhouses in winter and manure sown in spring next year.

Therefore, Xia Qing needs to find high-quality and low-cost bacterial powder to replace the high-quality and high-priced bacterial powder in Territory Nine. The low-priced fungus powder sold in the safety zone didn't know what the quality was, and Xia Qing didn't dare to try it easily.

She believes that with the ability of idols, making fungus powder is like playing, just depending on whether he is willing or not.

Zhang San really didn't disappoint his fans, "How much do you need, I'll take the time to get some in the past two days." ”

Xia Qing was moved, "Thirty catties is enough, third brother, how many points do you need me to make?" ”

Zhang San responded lazily, "No need to make it up, this thing is worthless." ”

Take a look, take a look! What is a quality idol? That's it! The depth of Xia Qing's powder pit goes straight to the center of the blue star!

After hanging up the phone, Xia Qing heard that everyone was discussing how to return the corn stalks to the field in the lord's channel.

Qi Fu advocated that the straw should be directly crushed and returned to the field, and Shi Fu advocated that the straw should be returned to the field after fermentation and decay, both of which were introduced in the agricultural knowledge broadcast, and each had its own advantages and disadvantages.

Li Si, a planting expert, appeared at the right time and ended the discussion with a cold and professional voice, "Corn straw is recommended to be used after fermentation and decomposition, because the organic acid produced by the direct return of straw to the field will accelerate the dissolution and release of calcium, magnesium and other elements in the soil, resulting in soil acidification. The soil of our cultivated land is already weakly acidic, and the increase in acidity is not conducive to plant growth. ”

Mother Zhao seized the opportunity to ask, "Fourth sister, is it better to plant wheat with alkaline soil or acidity?" ”

Li Si replied, "The ideal pH value for growing wheat is 6.1 to 7.5, and the wheat yield in this range is the highest. ”

The median pH value of wheat is 7, and the pH value range of wheat is equivalent to neutral or slightly acidic, and Xia Qing immediately wrote down this important knowledge.

Mother Zhao asked again, "Fourth sister, how do you measure the acidity and alkali of this plot?" ”

Li Si replied, "The pH value of the soil in different areas is not the same, if you want to know, you can send the soil to me for testing, free of charge." ”

Hearing that Li Si was going to measure the soil composition of the No. 4 territory, Xia Qing frowned.

Mother Zhao only arrived in the territory later, so she didn't know the situation. When they first arrived in the territory, they all bought PH test strips with Zhong Tao to test the pH of the soil in the territory, and Xia Qing knew that Zhao Ze also bought it.

Why didn't he keep silent, could it be that he forgot to test and lost it?

I have to say that Xia Qing's intuition is still very keen. Zhao Ze, who was gnawing on corn tortillas in the fourth territory, couldn't wait to stick his head under the table.

Mother Zhao, who didn't know it, hurriedly thanked her, "Okay, okay." I'll let Zhao Ze send it over later, it's our blessing to be able to farm next to you, the third brother and Captain Luo. ”

Xia Qing then asked, "Fourth sister, do you know what the soil pH range is for growing rape?" ”

Regarding how to plant rapeseed, Xia Qing did not mention it in the book he collected, nor did it appear in the "Planting Encyclopedia" issued by the base, nor did he mention it in the agricultural knowledge broadcast. Xia Qing seized the opportunity today and hurried to consult an expert.

Li Si gave an accurate answer, "5 to 8." ”

This pH range is larger than wheat, and every piece of cultivated land in her territory can be planted, Xia Qing carefully wrote it down.

Hearing Xia Qing ask about rape, Kuang Qingwei went online, "Sister, do you know?" If rape lacks boron, it is not only easy to lodge, but also will only bloom but not set seeds. I got an organic boron fertilizer made of seaweed and brown algae as raw materials, mixed it with water and watered it, and 2 catties of land per acre of land was enough. Do you want to? ”

Xia Qing didn't answer immediately, but asked, "Is our soil boron deficient?" Does Brother Qing know how much boron content should be in the land where rape is planted? ”

Xia Qing used her own element detector to test the soil in the territory, and she remembered that the soil contained boron, and the content was not low, it seemed to be 72mg/kg, but Xia Qing couldn't say this directly.

Because the Yi element detector is a high-precision instrument, she can't announce that she has this kind of instrument, which will cause trouble.

Concord Qingwei couldn't answer Xia Qing's question accurately, so he turned to Li Si for advice.

Li Si replied, "The full boron content measured in Territory Nine is 70mg/kg, but the available boron content is only 0.1mg/kg. The effective boron content of rapeseed, radish and sugar beet should be above 0.5mg/kg, and boron fertilizer is required. The situation in Territory 3 needs to be tested on a case-by-case basis to know. ”

Xia Qing, who was pregnant with a heavy treasure, didn't want to hand over the soil in the territory to Li Si for inspection, "Thank you, Fourth Sister, our territory is not far away, and the elemental composition must be about the same." Brother Qing, I'll get two catties of boron fertilizer. ”

Xia Qing placed an order without asking the price, because no matter how many points there are, this fertilizer has to be used. Otherwise, her rape will be planted in vain.

Moreover, Kuang Qingwei promised that the goods to her would be based on the purchase price, Xia Qing publicly asked about the price, so how did Kuang Qingwei answer?

Two catties of boron fertilizer is not much for Xia Qing.

In addition to the half-catty of rapeseed rewarded by the territorial management department, Zheng Kui told Xia Qing when he came over last time that rapeseed would be sold openly at the autumn agricultural products fair, and Xia Qing could still buy half a catty.

According to the germination rate of less than 50% of yellow light seeds, one pound of rape seeds is not even enough to plant one acre of land, and two pounds of boron fertilizer are not needed.

The remaining boron fertilizer, Xia Qing plans to use it for radishes in the spring of next year. If Li Si didn't say it, Xia Qing wouldn't understand that the radish he planted grew small, and it was boron deficient.

Originally, boron was also divided into total boron and available boron. It turns out that a lack of available boron can reduce the yield of crops that need boron.

Farming is really a science. (End of chapter)
