example 1

[0018] The corn variety is Zhengtian 68, and the zucchini variety is Canberra. The corn seeds and zucchini seeds were collected and soaked in water for 6 hours, and then germinated on the sand base. Moisture rises after the land is leveled, and the row direction of corn and zucchini is north-south, and two rows of zucchini are interplanted on both sides of one row of corn; the moisture surface of corn is 50 cm wide and 15 cm high; the moisture surface of zucchini is 75 cm wide and 15 cm high. Drip irrigation belts were laid on the zucchini and corn rows. Without fertilization and irrigation, the corn rows were covered with atrazine-containing herbicide film, and the zucchini rows were covered with black film. After accelerating the germination, the membrane is sown, the sowing depth is about 3cm, the distance between the plants of corn is 20cm, the distance between plants of zucchini is 40cm, the row spacing between corn and zucchini is 50cm, and the row spacing between two ro...

[0028] The corn variety is Green Superman, and the zucchini variety is Johnson & Johnson 103. The corn seeds and zucchini seeds were collected and soaked in water for 8 hours, and then germinated on the sand base. Moisture rises after the land is leveled, and the row direction of corn and zucchini is north-south, and two rows of zucchini are interplanted on both sides of one row of corn; the moisture surface of corn is 50 cm wide and 15 cm high; the moisture surface of zucchini is 75 cm wide and 15 cm high. Drip irrigation tapes are laid on the zucchini and corn planting rows, and covered with black film weeding film without fertilization and irrigation. After germination, the membrane is sown, the sowing depth is about 3-4cm, the distance between the plants of corn is 25cm, the distance between plants of zucchini is 40cm, the row spacing between corn and zucchini is 50cm, and the row spacing between two rows of zucchini is 100cm. Use an electric pump to apply water and ferti...

[0038] The corn variety is Zhentian, and the zucchini variety is Feiyue. After the corn seeds and zucchini seeds were soaked in water for 10 hours, they were germinated in soilless culture. Moisture rises after the land is leveled. The row direction of corn and zucchini is north-south, and two rows of zucchini are interplanted on both sides of one row of corn; the moisture surface of corn is 50 cm wide and 15-20 cm high; the moisture surface of zucchini is 75 cm wide and 15-20 cm high. Drip irrigation belts are laid on the zucchini and corn planting rows without fertilization and irrigation, and covered with black film weeding film. After accelerating the germination, the membrane is sown, the sowing depth is about 3cm, the distance between the plants of corn is 25cm, the distance between plants of zucchini is 40cm, the row spacing between corn and zucchini is 50cm, and the row spacing between two rows of zucchini is 100cm.

Abstract

The invention discloses a corn-zucchini-intercropping water-saving fertilizer-saving cultivation method. A corn variety and a zucchini variety with a picking time ranging from 90 days to 120 days are used, and a planting mode of intercropping two lines of zucchini with one line of corn is designed. The line spacing between the corn and the zucchini is 50 cm, and the line spacing between two adjacent lines of zucchini is 100 cm. The plant spacing of a single line of corn ranges from 20 cm to 25 cm. The plant spacing of a single line of zucchini ranges from 40 cm to 60 cm. Drop irrigation of an under-membrane water-fertilizer integrated nutrient solution is conducted, the amount of fertilizers and water used is reduced greatly, and a large amount of labor input is saved. Fresh corn weighing 640 kg to 850 kg is additionally harvested per mu on the basis of small-scale production increase of zucchini in unit area.

Description

technical field [0001] The invention relates to a water-saving and fertilizer-saving cultivation method for intercropping corn and zucchini, and belongs to the technical field of crop planting. Background technique [0002] Due to the gradual reduction of the cultivated land area in our country, coupled with the fact that the large-scale planting and long-term continuous cropping of some grain and economic crops have become more and more serious, the production of agricultural products has been greatly reduced, and the supply of agricultural products has become increasingly tense. Adopting new planting techniques and increasing the yield per unit area is an effective way to increase the supply of agricultural products. Reasonable intercropping can reduce the use of pesticides, and at the same time significantly increase the yield and output value of crops per unit area. [0003] Zucchini is a staple vegetable with a large market demand, but its resistance to large-scale con...
