Chapter 47: Cultivated land and upgrading materials

　　 Since it has been decided to exchange vegetables for materials, the planting greenhouse is obviously the place where Chen Xin needs to be upgraded most now.
At present, half of the land in Chenxin’s planting greenhouse is planted with carrots, and it will take about two months to harvest. The other half of the land was previously planted with lettuce and cabbage, which has just been harvested. Apply fertilizer, then plow the soil to replant new seeds.
　　While re-fertilizing the land, plowing is also required, which is commonly referred to as plowing or plowing.
　　 This is to break up the clumped part of the soil to make the soil looser, making it easier for crops to grow. If fertilization is carried out at the same time, the fertilizer can be turned into the depth of the soil so that the crop can better absorb the nutrients in the fertilizer.
　　 Plowing is one of the most important parts of the entire farming process, and it is also the most tiring of all farming activities. This is why there were cattle and even war horses to plow the land in ancient times.
　　 Because it is too tiring to turn over a piece of land with manpower alone, the use of animal power can greatly save manpower, and it can also improve the efficiency of farming and save time.
　　 After all, cattle farming and human farming are completely different concepts.
　　 However, Chen Xin's planting greenhouse was too small, and he had no cattle to use, so he could only use his to turn the ground bit by bit.
　　 Fortunately, the area of ​​land to be turned over by Chen Xin is not large, and the temperature of the planting greenhouse is constant. He does not need to rush to farm, as long as he finishes turning over and plant the seeds.
　　 But even so, it took Chen Xin more than half a day to till the fifty square meters of land and re-sprinkle the seeds.
Looking at the land he had finished ploughing, Chen Xin hammered his back. He felt a little emotional that doing farm work was really tiring work. At the same time, he wondered if he should upgrade his farm tools when upgrading the greenhouse. Improve the efficiency of farmland.
　　With the upgrading of the planting greenhouse, the planting area will definitely increase, and the increase in the planting area will inevitably be an increase in workload.
Although there is nothing to do in the refuge and farm work is good, this kind of manual labor really makes him feel a little bit choking for Chen Xin, who has not done any farm work in the first 30 years of his life. For farming, it doesn't matter if the area is small. When the planting area increases, the use of mechanical power is the correct way to improve efficiency.
　　 Maybe I can find Mo Qingyan for a few small agricultural machines? Although the precious survival points can be used to upgrade farm tools, Chen Xin feels that it should not be so wasted. After all, small agricultural machinery is not difficult to get started even in this age of the end of the world.
　　 In addition to small agricultural machinery, Chen Xin also plans to get a few more fill-in lights. This is an essential tool in the planting greenhouse and also a material for upgrading the planting greenhouse.
　　 As for the other materials for the upgrade of the planting greenhouse, steel and cement are basically the building materials that will inevitably be used in the expansion of the planting greenhouse.
Of course, if Chen Xin adds all kinds of equipment required for hydroponic planting to the upgraded materials, then when upgrading the planting greenhouse, Chen Xin will not only expand the land area of ​​the planting greenhouse, but also provide an extra layer of water. Cultivate the planting plate, so that the planting area of ​​the planting greenhouse can be doubled.
　　 This is also the difference between using materials to upgrade and using survival points to upgrade. Using survival points to upgrade can only choose one of the two upgrade schemes given by the system. There is no way to choose all of them in one upgrade.
　　 But if you use the material to upgrade, there is no such trouble. As long as you can meet all the materials required for the upgrade, you don't need to consider the issue of choosing one at all. You can upgrade both at once.
　　 Regarding the functional difference brought about by the two upgrade methods, Chen Xin understood that this may be a function set by the higher civilization to increase the fun of the survival game when the system was created.
　　 After all, for higher civilized individuals who can play survival games, what they want is a better gaming experience.
　　 If you just stay in a certain place and play doomsday survival by accumulating survival points to upgrade items, obviously people feel a bit negative, and the game experience is also poor, after all, there is no sense of actual participation.
　　 Maybe you will spend some time in the early stage to build a hiding place or survival hut for yourself, but with the storage of survival points, you can completely give up going out to collect resources and work on your own to improve your living conditions.
　　 But collecting upgrade materials by yourself is different. After all, the resources collected by yourself are used for upgrades. Watching the residences built by yourself get better and better. This will obviously greatly satisfy the sense of accomplishment and participation of those players.
　　 And collecting resources to upgrade can also save survival points, which means that the system is changing directions to encourage the use of resources to upgrade.
　　 After all, resource upgrades need to save some survival points. When collecting materials, you can save enough survival points. UU reading www. This invisibly increases the survival probability of players who use resources to upgrade.
　　 Especially resources can be stored in advance, as long as there are enough resources and survival points, they can be upgraded.
　　 As for those players who directly use survival points to upgrade, on the one hand, the items they upgrade have weaker functions, and on the other hand, if they only use survival points, their upgrade progress will undoubtedly be much slower than players who use resource upgrades.
　　 But these may be just games for higher civilizations, but for Chen Xin, these are treasures that can save lives and greatly increase the probability of his doomsday survival.
　　 Thinking of this, Chen Xin also hurriedly made a list and confirmed what he needed.
"One hundred kilograms of steel, five bags of cement, a set of hydroponic planting equipment, supplementary lights..." Chen Xin counted the resources he needed one by one, and couldn't help but shook his head: "This is a lot of things. I want to change to these things, I'm afraid it is not going to be bleeding."
Chenxin’s planting greenhouse has half the area of ​​carrots that can only be grown and harvested after three months of planting, and the other half of the vegetable production is extremely limited. Before upgrading the planting greenhouse, I want to rely on the current vegetable output to change to what I need. , Chen Xin felt that he might have to provide all of his monthly output.
But it doesn’t have to be too rushed. He can first ask Mo Qingyan to help collect supplies through Uncle Ding’s relationship, first use the vegetables produced this month as a deposit, and wait until the carrots are harvested next month before making the final payment. Settlement.
　　With these materials, Chen Xin can upgrade the planting greenhouse and increase the planting area of ​​the greenhouse to four times its current size.
　　 Moreover, Chen Xin upgrades using the system, which does not have the time required for normal construction, which can save time.
