ANNUAL STRIP COMPOUND EFFICIENT PLANTING METHOD FOR FOODIVEGETABLE-OILICOTTON Technical Field
[0001] The disclosure belongs to the field of agricultural technology, in particular, to an annual strip compound efficient planting method for foodlvegetable-oillcotton. Background Art
[0002] Continuous cropping obstacles refer to the abnormal growth and development of crops caused by the continuous cultivation of the same crops or related crops on the same soil. Symptoms are generally poor growth and development, yield and quality decline, and in extreme cases, there are local dead seedlings, no seedlings or seedlings being not prosperous; most of the damaged plants have browning, reduced branching, low vitality, and narrow distribution, resulting in a decline in the ability to absorb water and nutrients. Obstacles are generally obvious in the early stages of growth, and can often be recovered to varying degrees in the later stages. Continuous cropping obstacles have significant differences among plant families and genera. Crops that are prone to continuous cropping obstacles are concentrated in Solanaceae, Leguminosae, Cruciferae, Cucurbitaceae, and Rosaceae, while a variety of gramineous food crops such as wheat, rice, and corn, the continuous cropping obstacle is not obvious. There are many reasons for continuous cropping obstacles, including excessive nutrient consumption, deterioration of soil physical and chemical properties, increased pests and diseases, and accumulation of toxic substances (including allelopathy, etc.). Its occurrence is affected by various environmental conditions. The number of continuous cropping (generally, the more the number of the continuous cropping, the longer the period, the heavier the continuous cropping obstacles), the nature of the soil (usually the clay is heavier than the sand, and the cultivation in protected land is more than the cultivation m open land) and improper management of post-cropping water and fertilizer will increase the obstacles.
[0003] Cotton and peanuts are crops that avoid continuous cropping. The main problems in continuous cropping are as follows: (1) Diseases and pests are aggravated. According to incomplete statistics from the agricultural technology department of Lijin County, among the 33300 hm? cotton planted in the county, the arca of repeated cropping is more than 80%, and most plots have been continuously cropped for more than 3 years. Continuous cropping is common in cotton areas. Repeated cropping and continuous cropping lead to an increase in the area of verticillium wilt, especially in the seedling stage. As an important oil crop in China, peanuts account for a large proportion of continuous cropping area. According to the survey, more than 20% of continuous cropping
“0. fields of peanuts in Shandong Province account for more than 40% in some major producing counties, which directly led to aggravation of leaf spot and insect pests in continuous cropping.
[0004] (2) Premature aging increases. Due to continuous cropping for many years, increased pests and diseases and unreasonable fertilization make soil nutrients in cotton and peanut fields unbalanced. and premature aging tends to aggravate, which has a greater impact on the production of cotton and peanuts. For continuous cropping for 2 to 3 years, the average output is reduced by more than 20%, and with the increase of continuous cropping years within a certain period of time, the rate of production reduction will increase. reaching more than 50%, even some plots are close to dead in production.
[0005] (3) Ecological environment is affected. Due to many problems caused by continuous cropping, farmers will not hesitate to increase the use of pesticides and fertilizers to alleviate the problem of continuous cropping obstacles in order to increase production. However, the input and output do not match the ecological environment, especially ecological environment is greatly affected. This pollutes the soil and water resources, causes soil compaction, and destroys the soil structure; meanwhile, this also has a toxic effect on beneficial organisms and adversely affects the ecological balance.
Summary
[0006] In view of the problems existed in continuous cropping for cottons and peanuts in Huang He River and Huai He River areas, the disclosure provides an annual strip compound efficient planting method for foodlvegetable-oillcotton, which is conducive to ventilation and light-transmitting of wheats and cottons, giving full play to the marginal effect of high-stem crops, and solving the continuous cropping obstacles of cottons and peanuts for long time.

ie (6) after harvesting the wheat in early June, performing rotary tillage and soil preparation, and planting summer-planting peanuts right away: (7) after harvesting the cotton in mid to early October, sowing the wheat, and after harvesting the peanuts, sowing the spinach: (8) going round and beginning again to realize the annual strip compound efficient planting for food-vegetable-oil-cotton.
[0008] Prior to the performing rotary tillage and soil preparation in the step (1), a high-quality organic fertilizer of 1500-2000 kg/acre, a compound fertilizer (15-15-15) of 50 kg/acre, and a slow-release nitrogen fertilizer of 20 kg/acre are spread.
[0009] Prior to the performing rotary tillage and soil preparation in the step (2), the compound fertilizer (15-15-15) of 40 kg/acre is spread.
[0010] Prior to the performing rotary tillage and soil preparation in the step (3), the compound fertilizer (15-15-15) of 50 kg/acre 15 spread.
[0011] To facilitate mechanized operation, the cotton is planted in 4 rows, in “wind/narrow row” mode, with a row spacing in the middle of 76cm, a row spacing on both sides of 70cm, and a plant spacing of 20cm; the peanut is planted in 6 rows (3 ridges), with a ridge spacing of 85cm, a ridge height of 10 cm, 2 rows per ridge, a narrow row spacing of 30cm, a hill distance of 15cm, and 2 per hill; a row spacing between the cotton and the peanut is 47 cm: 12 rows of the wheat are sowed at equal row spacing, with the row spacing of 18-20cm; the spinach is spread.
[0012] According to the complementary characteristics of long-stalked and short-stalked crops of wheatlspinach and peanutlcotton, the disclosure makes full use of resources such as light and heat, which is conducive to the ventilation and light transmission of wheat and cotton, and exerts the marginal effect of long-stalked crops. so as to realize the simultaneous planting of two crops and the annual planting of four crops for promoting the growth of various crops.
[0013] The disclosure has the following beneficial effects: (1) Achieve sustainable development of agriculture With the planting mode of foodlvegetable-oillcotton, the obstacle in long-term continuous planting of single crops for cotton and peanuts is alleviated, and the annual crop rotation and change of crops are realized, which is conducive to fertilizing the soil, reducing the occurrence of diseases and insect pests in single-crop planting, and reducing the application of fertilizers, thereby improving the quality of the ecological environment and achieving sustainable development of agriculture.
[0014] (2) Guaranteed output With the planting mode of foodlvegetable-oillcotton, the single planting structure of wheat- corn is changed, the problems such as caused by soil compaction, decrease in soil fertility, and
-4- decline in soil productivity caused by the single-planting mode is solved and the annual continuous cropping is achieved, which are conducive to fertilizing the soil, increasing ecological diversity and maintaining sustainable development of agriculture; with the planting mode of foodlvegetable-oillcotton, the combination of land farming and land cultivation is achieved, the repeated cropping index and the land equivalent ratio are increased, and the system output and benefits are significantly improved.
