When it comes to crop planting, it must be determined according to the topography. I am located in the north of Henan Province. Generally, corn is interplanted with melon, and cotton-padded soybeans are planted with cantaloupe, which can increase the yield. Watermelon and melon go down, and corn and soybean cotton wool grow up. Pinus koraiensis and wild vegetables can be planted in the returning farmland, and Korean pine can be planted by grafting method. This kind of Korean pine can be grafted on pine cone for six or seven years. Korean pine is three meters by four meters, and wild vegetable tender buds can be planted in the air of Korean pine. The tender buds are perennial plants, and economic benefits can be seen in the second year of planting, so that the returning farmland can be used, and 2,000 tender buds 1 mu can be planted, the first.

In the case of spring, there are more than twenty kilos of tender sprouts, and about thirty-five kilos of tender sprouts and terminal sprouts are needed in spring. 1 mu of land produces about two hundred and fifty kilos of terminal sprouts. In fact, the terminal sprouts can be sold for three thousand to four thousand dollars. After the terminal buds are worshipped, the lateral buds will come out. We only worship two lateral buds, and the lateral buds are about seventy times lighter, and then one kilo, because the light price of the lateral buds is also cost-effective, generally. You can also sell it for about 2,000 yuan, and the income per acre of land is about 5,000 yuan. If the economic benefits of producing and manufacturing thorn buds in the tender winter are doubled, Korean pine can also make profits in a few years, and it is not clear whether it will help you.

The strip-shaped compound cultivation technique of corn and soybean is located in Meishan City, Sichuan Province, in the southwest of Sichuan Basin, in the middle and upper reaches of Qingyi River, and governs Dongpo District, Pengshan District, Renshou County, Hongya County, Danling County and Qingshen County. Hongya has a suitable climate, rich and colorful heat resources, and basically good agriculture. Our city has a planting area of 290 square kilometers. In recent years, under the strong leadership of the municipal government and the municipal people's government, we have persisted in the general idea of "stabilizing the cultivated land area, enhancing the development potential of output, accelerating the scale, promoting the steady increase of grain crops and increasing farmers' income", and made great progress in grain production and quality improvement. In 20 18, the total grain output of our city reached1238,000 tons, and the steady increase of output was completed. The strip-shaped compound cultivation technology of corn and soybean is a key cultivation technology and planting mode in hilly areas of our city, which can realize the combination of agricultural machinery and vehicles under the condition of intercropping in dry fields, further improve labor efficiency, achieve a relatively high degree of unity between the automation of intercropping sowing and harvesting machinery and the high efficiency of increasing production, and have obvious economic and environmental benefits, which has promoted the increase of farmers' income.

The planting of grain crops usually can reasonably arrange the row spacing of crops, so that the crops can be layered and shaped at intervals, which is beneficial to the natural ventilation of crops, the light transmittance standard, the utilization rate of solar energy, the photosynthesis of crops and plants, and the full use of the advantages of various crops to make farmers rich. Garlic can grow potatoes, Chinese cabbage, and the smell of garlic can kill insects and reduce the occurrence of diseases and pests. Pumpkin and peanut kernels can be planted among corn, which can effectively alleviate the damage of corn, and pumpkin flowers can attract the black egg bee, which can reduce the damage to corn. Green pepper can be planted between corn, and planting corn and pepper line by line can reduce pests and diseases. Pepper is afraid of drying corn and just can block the light. Mung beans and sweet potatoes can also be planted between the glutinous rice. Corn and lentils are mixed, and when they are mixed together, farmers will benefit from each other and become rich. Onion and carrot planting can drive pests and diseases farmers to get rich. Some castor can be planted between soybean and peanut kernel, which can further reduce the corrosion of soybean and peanut by pests.
