(1) Selecting a site and building a garden: and (3) selecting sandy loam land with medium fertility to build a garden, applying 3-4 tons of thoroughly decomposed farmyard manure, and deeply turning to enable the soil to be cured.
(2) Variety: according to local climate conditions, 1-year-old 'Ranis' soft-seed pomegranates are selected for introduction planting, and cotton is selected from cotton No. 87 varieties.
(3) And (3) nursery stock treatment: before the seedling of Henan spring Liu Goudan of 18 days of 3 months of 2021 does not germinate, 1-year-old high-quality "Denis soft-seed pomegranate" seedling is prepared, and after the seedling is transported, the seedling is soaked for 24 hours in time, rooting powder treatment is implemented, and temporary planting is implemented.
(4) Planting: digging deep holes of 80cm x 60cm with row spacing of 2.0mx5.0m for soft seed pomegranate plant of "Raney" and separating surface soil and core soil, and placing on one side; and 3, carrying out field planting on the pomegranate seedlings on 27 days, taking the seedlings from the temporary planting field along with planting, reducing transpiration and water loss of the seedlings, planting the seedlings in a creeping manner at an inclination of 30 degrees to the south, and planting cotton seeds to be planted at a row spacing of 4 m.
(5) Sowing: the cotton sowing date is 2021, 4 months and 10 days, the cultivation mode of sowing and covering mulching films with equal row spacing is adopted, the sowing width is 4m, the interval is 1m, and the row spacing is the field planting of the pomegranate.
(6) And (3) film and soil covering: after the pomegranate is planted, the tree is covered with a film, and root fixing water is irrigated thoroughly, so that no wind barrier exists in the field; therefore, when the soil on the surface layer of the field is semi-dry, the middle part of the seedling is covered with soil for 5cm thick, and the seedling is pressed down, so that the transpiration and water loss of the trunk are reduced by wind pumping; and removing the covering soil when the cotton seedlings reach about 15cm after 5 months and 25 days, and continuously providing a windbreak for the pomegranate seedlings by the dynamic growth of the cotton in the later period.
(7) And (3) water and fertilizer management: after root fixing water is irrigated thoroughly, the principle of a small amount of water for many times is followed, and then irrigation is carried out once every 15 days until 8 months is reached, and watering is controlled; no fertilizer is applied before the sprouting of the pomegranate seedlings, and 30-50g of nitrogen and phosphorus fertilizer is applied to each plant with the new branches reaching about 30cm after the sprouting.
(8) And (3) field management: raking the ground and loosening the soil before planting the pomegranate seedlings, raising the ground temperature, timely erasing the sprouts within 30cm of the basal part of the trunk after the planting seedlings sprout, pruning the branches on the backs, and weeding at regular time.
The investigation was carried out 6 months in 2021, at this time, about 20cm for 12 cotton seedlings, and about 35cm for the inclined height of the pomegranate seedlings; and measuring the drainage length of 15 randomly selected nursery stock branches, and calculating the average drainage length of different space heights. The survey results are shown in table 4:
table 4 12 Soft seed Granati intercropping cotton (6 months)
From the test results in tables 2 to 4, it can be found that: in three different interplanting examples monitored in 6 months of 2021, the "tanis" soft-seed pomegranate and winter wheat interplanting has obvious prevention effect on inhibiting the extraction of branches, and the survival rate of fruit trees is improved by about 30%.
Fig. 3 shows, wherein (a) is a composite planting total plane graph, (b) is a field planting effect schematic view, and (c) is a plant growth time sequence change schematic view of different months. As shown in fig. 3-4, long-term field observation shows that when soft-seed pomegranate seedlings are planted at the bottom of 3 months, the average height of winter wheat is about 15cm, and after winter wheat enters a jointing period, the plant height is rapidly increased to form a windbreak, so that the air humidity is improved, the trunk transpiration is reduced, and a good micro-habitat is improved for the survival of soft-seed pomegranates; after sowing in the middle and late 3 months, the plant height of the melon is within 10cm in the early 5 months; the effect of providing good environment for the pomegranate is weak after 6 months is less than 20 cm; sowing cotton in the last ten days of 3 months to 4 months, squatting seedlings before the end of 5 months, and controlling the seedling height to be within 20 cm; therefore, the seedlings of the soft-seed pomegranate with the plant height of 60cm can not be directly and effectively protected in the survival period of 4-6 months when interplanted with melon or cotton.
