The implantation methods planting corn intercrop Semen sojae atricolor interplanting Radix Ipomoeae of the present invention, take full advantage of, the growth cycle of each crop, reasonably utilize respective growth time, carrying out land utilization ratio thus maximizing, make use of rhizosphere process between the kind between corn and soybean and Radix Ipomoeae simultaneously, improving sweet potato nutrient, promote Semen sojae atricolor fixed nitrogen, thus the total output of the corn and soybean improved on unit cultivated area and Radix Ipomoeae.
The method have the benefit that the implantation methods proposing a kind of corn intercrop Semen sojae atricolor interplanting Radix Ipomoeae, it is possible to comprehensive utilization soil, improve per mu yield crop yield, and reduce and cultivate intensity and reduce planting cost.
Detailed description of the invention
Below in conjunction with specific embodiment, the implantation methods of a kind of corn intercrop Semen sojae atricolor interplanting Radix Ipomoeae of the present invention is described in detail.
The selection of sowing kind: Semen Maydis should select stamp, early-maturing variety on high stalk, high resistance, blade, is so beneficial to and reserves enough growing spaces to Semen sojae atricolor, Semen sojae atricolor should select the kind of high stalk, resistant to lodging, growth cycle length, and Radix Ipomoeae should select, and tendril is undeveloped.
2, seeding process: first carry out overall soil and loosen the soil and be beneficial to the growth of later stage crop root, carry out the operation in maize seed hole again, degree of depth 20cm should be accomplished in maize seed hole, laterally should be a line narrow row to join a line wide row and carry out, and narrow row spacing is 20cm, wide row spacing is 40cm, first such setting is beneficial to two row Semen Maydiss and concentrates fertilising, improve the utilization rate of fertilizer, and it is beneficial to the ridging in Semen Maydis mid-term and the ridging requirement of Radix Ipomoeae plantation, using of base fertilizer is carried out after treating kind of hole construction, base fertilizer is generally with calcium superphosphate, ammonium chloride, coordinate fertilizer again, because be Semen sojae atricolor and Semen Maydis sowed simultaneously, so potash fertilizer and nitrogenous fertilizer should once use sufficient. kind hole is disposed and carries out the plantation of Semen Maydis and Semen sojae atricolor afterwards, Semen Maydis adopts the method that first nursery is transplanted again, and the method that Semen sojae atricolor adopts directly sowing, Semen Maydis is generally adopted each kind of hole plantation 2 strains, 3-4 seed of soybean planting, because transplanting survival rate is relatively high, directly sowing germination and survival rate it cannot be guaranteed that, until Semen sojae atricolor is once augmented when growing three leaves, one kind of basic maintenance is cheated 2 strains and is advisable, until carrying out using of fertilizer in mid-term when Semen Maydis grows to 40-50cm height, it is generally 75kgN hm-2, Diammonium phosphate (DAP) 75kg hm-2, such purpose had both met Semen Maydis and the demand of Semen sojae atricolor fertilizer in mid-term, demonstrate,prove again the demand of Radix Ipomoeae base fertilizer, Term Fertilization is complete carries out ridging operation, general ridge height is advisable with 30cm, now carry out Radix Ipomoeae plantation, plantation spacing is 10cm, so both ensure that the thick requirement of the soil of Semen Maydis and Semen sojae atricolor, plantation for Radix Ipomoeae provides condition again, and the results of later stage Radix Ipomoeae are provided facility by ridging plantation, because Radix Ipomoeae is ripe in soil, Root growth is also more favorable for results. until during Semen Maydis maturation, corn stalk is cut down and removes, now remaining Semen sojae atricolor and Radix Ipomoeae, the growth busy season of Semen sojae atricolor and Radix Ipomoeae just, because Semen sojae atricolor strain is little, bar is high, Radix Ipomoeae throws oneself on the ground, tendril is relatively flourishing, so Semen sojae atricolor is without influence on the growth of Radix Ipomoeae, and the soybean mature time is early than Radix Ipomoeae, the combination of the nitrogen being beneficial to again in soil, and leave growth time for Radix Ipomoeae.
3, set principle: utilizing the growth between each crop different from harvest time, the trophophase of general Semen Maydis is about 120 days, Semen sojae atricolor about 150 days, and Radix Ipomoeae is also about 140 days, because than Semen sojae atricolor late two months sowing time, so gathering in the crops more late than Semen sojae atricolor. Such spacing sleeve cropping, has well held the growth time of each crop, the ingenious plantation reasonably utilizing season, compares and individually sows the utilization rate not only increasing soil, and influencing each other between each crop, make overall yield more be improved than independent sowing.
