Don’t stay too far away from water sources.

But the "new desert sweet potato" in this A-level knowledge is different. It has small and thick leaves, is extremely tolerant to drought and heat, has strong root germination ability, extremely deep root system, and amazingly tenacious vitality. It is resistant to sand burial and can survive in salt.

For growth on land with high alkalinity, as long as it is planted in large areas on the edge of the desert and supplemented with specific fertilizers, it can also form a suitable oasis climate and feed back the fertility of the land.

Its disadvantage is that the red fruits it produces are small in size, with a yield of about two thousand kilograms per mu, and are only the size of a child's fist, but it is sweet and glutinous and has an excellent taste.

Another advantage and disadvantage is that its vitality and reproduction ability are very strong, and it cannot be planted with other crops. It requires special chemicals to form a "protective embankment" to limit its growth to only one end of the desert and prevent it from eroding the normal

Fertile land for crops.

According to this knowledge, the new desert sweet potato can also be combined with poultry and livestock. The sweet potato leaves can be used as feed, and the animal excrement can be used as fertilizer for sweet potatoes, forming a good cycle of ecological environment.

Qin Ke was secretly stunned when he saw this. This new type of desert sweet potato is of great significance. It can not only reduce the food crisis, but also alleviate the farming crisis and control the expansion of the desert!

This is good for Xia Kingdom and even the whole world, especially farmers who live near the desert or in areas with particularly poor land. The new desert sweet potato is simply the best crop!

However, it is also quite difficult to cultivate. It requires multiple generations of complex mixed crosses to cultivate it. There are also several specific fertilizers and limiting agents that need to be made. If I really want to come up with a complete set of solutions, it will take no more time and effort.

few.

Qin Ke was most interested in such topics that could benefit mankind. He sent a message to Wei Xueming, asking him to urge the third team to collect sweet potato seeds from various places as soon as possible, so that he could go to the virtual scientific research laboratory to conduct virtual research on the new desert sweet potato.

Breeding experiments.

The second group's research work on special chemical fertilizers can start first. Qin Ke wrote some formulas and development methods for the second group to study on their own.

After finishing all this, it was already evening.

Qin Ke took Ning Qingyun on foot to a hotel near Qingmu University, where Qiu Sai's results conference, awards ceremony and dinner were all held.

At six o'clock in the evening, the results of the Qiu Sai finals began to be announced.
Chapter completed!
