Abstract

The invention relates to a growing method for interplanting summer maize in spring peanuts. Six rows of peanuts are interplanted between every two adjacent rows of maize; the summer maize is interplanted on the basis of ensuring that the production of the spring peanuts is not reduced or reduced slightly; the border row advantages of the maize is utilized; the individual production increase advantage is fully taken use of; the each mu yield is increased by more than 200kg. In the model, the utilization rate of light energy of an intercropping system is significantly improved, the land utilization rate is improved, the coordinated development of food crops and oil crops is realized, and the food production is increased ultimately under the premise of not decreasing the oil plants.

Description

Between a kind of Spring Peanut, overlap the implantation methods of summer corn

Technical field

The present invention relates to overlap between a kind of Spring Peanut the implantation methods of summer corn, belong to agricultural technology field.

Background technology

Corn is one of world's Three major grain crops, and development Maize Production is to alleviate the effective measure of China's grain security.Reasonably intercropping not only can increase productivity but also can efficiently, rationally utilize limited resources, increases Agricultural biodiversity.In the mountain and hill area of having a large population and a few land inconvenient big machinery operation, it at other crop field a small amount of corn of kind, is the desirable approach of development Maize Production.Especially peanut ground maize intercropping has outstanding performance, the reasonable combination of the two not only can efficiently be utilized the resources such as water, light, nutrient, can also make full use of the nitrogen fixation of peanut, reduce the input of nitrogenous fertilizer, reduce in agricultural production and excessively execute the pollution of nitrogen to environment.

7,000 ten thousand mu of the existing peanut cultivation areas of China, wherein Spring Peanut accounts for ten thousand mu of 3000-4000, and the area light thermal resource of general preferential species peanut is sufficient, all can meet maize intercropping growth needs, do not have natural conditions restriction.Between the spring flower dried rhizome of rehmannia, plant summer corn 1000-1100 plant/acre, the sowing of intercropping summer corn is late, and intercropping strain number is few, Spring Peanut is shaded not obvious, Spring Peanut output and nonoculture maintain an equal level or slightly reduce, and have increased summer corn limit row advantage simultaneously, fully excavate its individual plant production capacity.Can significantly increase yield of Summer Corn.Thereby but how reasonably between between Spring Peanut, overlap the object that summer corn reaches " increase grain and do not squeeze oil ", be the problem that those skilled in the art considers.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides a kind of implantation methods of Spring Peanut interplanting summer corn.

Technical scheme of the present invention is as follows:

An implantation methods for Spring Peanut interplanting summer corn, its concrete grammar is as follows:

Peanut, corn intermission seeding, late April is broadcast peanut, stays corn seeding capable, and late May and early June are broadcast corn; Between every 1 row corn, plant 6 row peanuts, 6 row peanuts are divided equally 3 ridges, 85 centimetres of every row spacings, and every bed planting 2 row, on ridge, line space is 35 centimetres; Every mu of 9000 caves of peanut, 2, every cave, 13.7 centimetres of cave distances, plastic mulching;

Every mu of corn is broadcast 1000-1100 strain, 35 centimetres of corn and peanut ridge back gauges, and with 60 centimetres of peanut line spaces, corn plants is apart from 18-20 centimetre.

Object of the present invention " increases grain and does not squeeze oil ", by dwindling peanut cave distance, ensureing under the prerequisite of Spring Peanut thickness of sowing, every mu of intercropping summer corn 1000-1100 strain, group structure is reasonable, leaf-area coefficient is suitable, utility rate of luminous energy is high, has higher effect of increasing production and economic benefit, can be in the large scale application of peanut main producing region.

Peanut pull-down distance, secrecy is consistent with nonoculture peanut, is guaranteeing that on the basis that Spring Peanut output does not subtract or slightly reduces, intercropping summer corn, utilizes maize intercropping limit row advantage, gives full play to its individual volume increase advantage, more than every mu of many harvesting corns 200kg.This pattern obviously improves the utility rate of luminous energy of Intercropping System, has improved land utilization rate, has realized the coordinated development of cereal crops and oil crop, finally reaches and is guaranteeing, under the prerequisite that oil-bearing crops do not subtract, to increase grain yield.

On the above plot of high fertility (more than the long-term per mu yield 400kg of Spring Peanut), 6 row Spring Peanut intercropping 1 row summer corns, the purer Spring Peanut output of doing of Spring Peanut output slightly subtracts, and mu increases income yield of Summer Corn more than 200 kilograms, Land Equivalent Ratio is higher than 1.3, and rate of growth reaches more than 30%.

Embodiment

Below in conjunction with embodiment, the present invention is further illustrated.

Embodiment 1

Take purely make Spring Peanut, summer corn is contrast, and 2 row peanuts, 4 row peanuts, 6 row peanuts, 8 row corns, 10 row peanut intercropping 1 row corns are set.Totally 7 processing.Concrete pattern is as table 1.Test is carried out 3 different regions.

Pure work one ridge 2 row of peanut, 85 centimetres of row spacings, two caves are apart from 17.4 centimetres, 9000 cave/mus.Intercropping peanut narrow row is apart from 35 centimetres, and cave distance is in Table 1, and corn plants is apart from 20 centimetres, and corn is apart from 35 centimetres, peanut ridge.

Table 1

Output and benefit are as following table 2:

In table, output is multi-point average.

Benefit in table: beautiful meterkilogram valency (2.2) * average yield+peanut kilogram valency (6 yuan) * average yield, other expenditure is identical, puts aside herein.

[0012] output and benefit situation are as can be seen from Table 2, every kind of pattern corn, peanut yield all compare lower than pure, within 1: 6,1: 8,1: 10, pattern Land Equivalent Ratio is all higher than 1.3, the peanut underproduction is in 10%, and synchronously increase production corn, surpass 30%, overall benefit is all higher than pure corn and the peanut done.Wherein 1: 6 pattern volume increase corn surpasses 240 kilograms, and benefit reaches 3107.1 yuan, purer do corn, peanut respectively high 1953.3 yuan, 328.5 yuan, economic benefit is very remarkable.If increase by 200 kilograms of calculating according to corn mu average yield, if the whole nation approximately has 60% Spring Peanut field (approximately 2,000 ten thousand mu) maize intercropping every year, the whole nation can increase income 4,000,000,000 kilograms of corns more, be equivalent to increase by 8,000,000 mu of pure corn fields of doing, to ensureing that China's grain security is significant more.
