According to your description, you described the compensation for young crops, and the compensation for land acquisition is not just the compensation for young crops. According to the provisions of China's land management law, the compensation for land expropriation belongs to land users, including compensation for the value of the land itself, compensation for young crops and attachments on the ground, and temporary resettlement subsidies. Young crops compensation fee is calculated according to 6- 10 times of your average annual output value in the previous three years. If you feel that the local compensation is unreasonable, please don't sign any documents, and protect your rights through legal channels such as reconsideration litigation in time, and ask a lawyer to intervene.
