TABLE 1 field soil improvement and interplanting mode
Note: the furrow width is the width of furrows between the ridges for planting rice/stropharia rugoso-annulata and culturing fish; the ridge height and the furrow depth are the height of the furrow and the ridge surface; the rice ditch with the water surface height is the water surface height of the planting ditch and the water storage height of the water surface of the fish ditch when the rice is planted. The oranges and fruit mulberries are both originally planted on the soil blocks for 3 years.
The land reclamation method of the test is a method for reforming the original land where the fruit mulberry and the citrus fruit are planted (the same reclamation method for the fruit mulberry and the citrus fruit are planted at the beginning), namely, furrowing is carried out between the citrus fruit and the fruit mulberry (actually, the soil between ridges is taken and added to the ridges to deepen the soil of the original shallow ridges).
The interplanting intercropping mode is as follows: sowing and cultivating rice seedlings in other fields, namely planting the cultivated seedlings in shallow ridges with water and ploughing in the middle and last ten days of 4 months or the last ten days of 5 months by adopting a seedling throwing mode, carrying out field management on the rice field according to the common management technology of rice for weeding, fertilizing and preventing diseases and insects, harvesting the rice before and after 9 months, draining water in shallow ditches, forming a shallow ditch with the width of 20cm in the middle of each ditch to enable each ditch to form two shallow ridges, and planting mushroom on the shallow ridges.
Taking stropharia rugoso-annulata as an example: the formula (1) is as follows: mulberry twig: 70%, chaff: 17%, wheat bran: 10%, gypsum: 2% of lime; 1%, and adjusting the ph value to 5-7.
(2) According to the formula, the mulberry twig sawdust, the rice husk and the like are proportionally added with water and uniformly mixed, so that the water content in the compost reaches 70-75%, the compost is pinched tightly by grabbing a base material with hands, and water drops out but does not flow linearly to be proper in dryness and wetness.
(3) The stropharia rugoso-annulata can be sowed at the temperature of 8-30 ℃ generally, the optimal temperature is 15-26 ℃, the sowing and cultivation season is suitable for being carried out in 9-10 months, the temperature is suitable after sowing, the hypha grows fast, and 4-6 months are needed from sowing to fruiting and harvesting in general.
A furrow is made on the ground, the furrow is shaped into a turtle back shaped furrow bed with the width of about 1.1m, the height of 20cm and the unlimited length, the distance between the furrow and the furrow is 20-40cm, drainage ditches are made, and the drainage ditches are also made around the furrow, and the ditches are deeper than the bottom of the furrow bed. After the bed is opened, spraying pesticide and sterilizing agent to make insecticidal sterilization treatment
(4) Firstly, laying a layer of fermented mulberry branch sawdust culture material on a bed with the thickness of about 8-10cm, then hole-sowing a layer of stropharia rugoso-annulata strain on the material surface, breaking the strain into pigeon eggs, dibbling by adopting a plum blossom with the hole distance of 10-12cm, then laying a layer of mulberry branch sawdust culture material with the thickness of 10-12cm, flattening and compacting the material surface by using a wood board after sowing, and tightly combining the strain and the culture material so as to facilitate germination and feeding growth of the strain. Covering the material surface with a straw curtain and a film, and keeping warm, moisturizing and spawn running.
(5) Observing the temperature and humidity change of the piled materials every day, uncovering the film for ventilation when the temperature of the materials is higher than 30 ℃, and spraying water for cooling. The ridge surface is dry, water is sprayed for moisturizing, and the water is required to be leakproof.
(6) The stropharia rugoso-annulata cultivation needs covering soil to produce good mushrooms, generally, after seeding for 30 days, namely hypha basically grows over a material layer, the soil is covered, the thickness is 2-3cm, and the compost is completely covered. The soil for covering is required to be loose, good in air permeability and water retention performance, rich in humus, 5.5-6.5 in PH and about 30% in water content. Fruiting is started 15-20 days after the soil is covered, temperature adjustment, moisture preservation and illumination management are needed to be done at the moment, namely, the temperature is kept between 12 ℃ and 25 ℃; the soil is kept in a wet state all the time, so that the relative humidity of air in the mushroom shed is between 85 and 95 percent; strong scattered light
(7) When the pileus of the stropharia rugoso-annulata fruiting body is not cracked or just cracked and the pileus is still bell-shaped, the stropharia rugoso-annulata fruiting body can be harvested, and the method comprises the following steps: holding the base of the mushroom stem with a hand, and slightly rotating and picking off the mushroom stem. And filling the harvested mushroom pit with soil, and repairing a soil covering layer to prepare for the growth of the next mushroom. The harvested mushrooms are sold on the market after the mushroom with soil is removed, and can also be frozen for fresh-keeping or dried for mushroom outlet
The stropharia rugoso-annulata generally grows at the ground temperature of more than 15 ℃, the higher the air temperature and the ground temperature is, the faster the fruiting is, and most of the areas in China are suitable for sowing at the temperature of 20-30 ℃ in 9 and 10 months; the temperature can be raised to 15-25 ℃ in 2-4 months in the next year, and the fruiting can be realized in 30 days as long as the temperature is 15-25 ℃ in the period, so that the rice can be replanted in 4-5 months.
Meanwhile, the field soil which is not modified into the form is used for carrying out a comparative test, the time and the water depth of putting water and drying water in the control field are basically consistent with those of the intercropping, and the rice planting and interplanting intercropping are completely consistent with the method.
Test results and score
The results of this test are shown in the following table: unit area is m 2 The yield is kg, the unit yield is kg/m 2
Table 2: patent method comparison test statistical table
As can be seen from the table above, the yield per unit of mulberry produced by Fangan county agricultural machinery and farming specialized cooperative society in a patent manner is increased by 2.79kg/m 2 The yield per unit of rice is increased by 0.02kg/m 2 The yield of Stropharia rugosoannulata is increased by 9.86kg/m 2 . Yingchangxi Tang agricultural development Limited company in Yingxian county adopts a patent mode to increase the yield of oranges by 4.16kg/m 2 Increase yield per unit of rice by 0.1kg/m 2 The yield of the stropharia rugoso-annulata is increased by 0.25kg/m 2 . The rice fruit mushroom relay intercropping method is proved to be feasible.
