Farmers in order to save land, will be in the already planted crops in the ground and then plant something else, hoping to pursue the maximization of land use. My family used to plant watermelon in the corn field, the harvest is not bad, is that it will affect the watermelon light rate, according to the fungus of the yin like wet habits can be combined with the corn shade and moisture habits of the combination of characteristics added to the planting, so that you can achieve the purpose of the corn and the fungus double harvest. At present, the most important set of mushroom is shiitake and mushroom, Ganoderma lucidum. Shiitake mushrooms and ganoderma lucidum are one of the specialties of our country.

. If the types of crops planted in sets are appropriate, it can play a role in promoting the absorption of nutrients by crops, suppressing crop pests and diseases, improving soil quality, and improving the role of water retention, soil retention, moisture retention and heat preservation in the field. ① to adhere to the high straw crop and low crop set seeding; in our local rural areas, spring corn open air sowing is after May 1, when the spring corn began to rise and grow tall, in the gap between the corn set seeding on the vegetable beans, kidney beans, and in the edge of the ground will also be planted cowpeas, these vegetables are the most vigorous growth in the summer, the flood season of the north is coming,

corn field can be set seeded with vegetables, you set planted with what vegetables are also available. However, in the corn field sets of what vegetables, will not affect the growth of corn, but all will affect the normal growth of vegetables, but also affect the vegetable yield, the reason is very simple corn field sets of cucumbers. Corn seedlings grow to 20 centimeters high, in the corn row spacing between the cucumber, plant spacing about seventy to eighty centimeters or so, not too dense. When the corn grows tall, cucumber will begin to stretch and climb seedlings, cucumber seedlings climbing along the corn stalks, save the next season of racks.

The purpose of vegetable set seeding is to increase production and income, so set seeding vegetables can not affect each other's growth, such as earning light, earning fertilizer and so on! Therefore, the principle of planting is: high set of short, long set of short, large set of small, etc., complement each other, to avoid the shortcomings! Although it is in the corn field seedlings, but each time to make up is not corn, generally replanting are beans or cucumbers a class of vegetables. Not only in the corn field replanting is beans or cucumbers, usually also in the corn between the two rows, set in beans or cucumbers.
