fig. 1 is a flowchart of a method for interplanting festuca arundinacea in a camellia oleifera forest according to an embodiment of the present application.

Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.

The following describes the planting method of the camellia oleifera forest interplanting festuca arundinacea according to the present application with reference to fig. 1.

As shown in fig. 1, the planting method for interplanting festuca arundinacea in the oil tea forest provided by the embodiment of the application comprises the following steps:

s1: preparing soil;

s2: pre-sowing treatment;

s3: sowing;

s4: managing after sowing;

s5: and (5) seedling management.

In the step S1 provided by the embodiment of the present application, the soil preparation method includes: the weeds in the orchard are removed by manpower or machinery before sowing, and the orchard is turned over, the depth is about 10cm, preferably 10-15 cm, the whole fine ground is leveled, and the root systems of the fruit trees are prevented from being hurt.

In the step S2 provided by the embodiment of the present application, the method for processing before sowing includes:

seed dressing treatment before sowing, namely, the thatch seeds are lighter and smaller, and the thatch seeds feel somewhat difficult when being spread, so that the seeds are uniformly sown in windless days, and fine sand or dry fine soil and seeds are used for 10-8: 1, if sand is selected for sowing, the sand is mixed at night, the humidity of the sand is 40-50%, the wet hand feeling is good, the sowing is carried out in the next day, the seeds can absorb water and expand after being mixed, so that the seeds can germinate in advance in one day, and the phosphate fertilizer can be used for replacing fine sand soil for sowing.

In the step S3 provided by the embodiment of the present application, the seeding method includes:

(1) The sowing time is preferably from the last 9 months to the middle 10 months, or the sowing can be carried out according to the time of sowing the milk vetch in the rice field. The seedlings can emerge after 10 late days, but the seedlings are small and irregular in growth potential difference and unsafe in overwintering, and the seedlings are easy to damage and die due to the fact that the small root systems of the seedlings are shallow in soil. The higher elevation plots are suitably advanced in sowing time. The seeds can be sowed in 3 months of the next year, but the growing period of the festuca arundinacea is shortened, and the festuca arundinacea and the spring weeds are symbiotic, so that fertilizer water and weed management are required to be increased, the grass growing amount is improved, and the coverage effect is ensured.

(2) The sowing mode can be selected from various modes such as broadcasting, drill sowing, hill sowing and the like. The method is mainly based on a broadcasting mode under the condition of a common garden, and is simple, convenient and efficient in operation. When the gradient is larger than 15 degrees, in order to prevent seeds from losing along with rainwater, drill sowing is needed, the row spacing is determined according to the soil quality, the row spacing for planting the medium-soil orchard fescue is 30cm, the row spacing of the high-soil orchard can be properly increased, for example, 35-40 cm, and the row spacing of the poor-soil orchard is properly reduced, for example, 20-30 cm. Particularly steep slope plots (generally having a slope greater than 30 deg.) can be sown in holes.

(3) The sowing quantity is 1.5-2.0 kg/mu as the sowing quantity standard.

(4) The soil is covered by sowing, and after sowing, the seeds are lightly pulled by a harrow (or a bamboo harrow) or swept by a broom on the soil surface, so that the soil is thinner, the soil can be pressed under certain conditions, the soil is compacted, and the effect of hanging the seeds is prevented. When drill sowing or hole sowing, the depth of the sowing ditch or hole is 1-2 cm, and soil is covered immediately after sowing, and then compacting is carried out.

In the S4 provided by the embodiment of the application, the method for managing after sowing includes:

(1) The principle of early weed suppression by the thatch is that the growth advantage of the thatch is utilized, a covering is formed on the ground as soon as possible, a light-proof or light-lack environment is caused, seeds of the weeds cannot germinate, the weeds cannot grow, if the seeds cannot be completely covered, light can pass through the exposed places, and the seeds of the weeds can easily germinate under the conditions of proper moisture and temperature. So the flatter and finer the soil is, the higher the germination rate, the faster the earth surface is closed, the better the coverage is, the better the effect of inhibiting weeds in the future and the effect of rotting and improving soil is.

(2) The soil moisture is preserved, the relative water content of the suitable soil for the emergence of the thatch is 65-85%, and the temperature is about 20 ℃, and is generally between 20 and 28 ℃. The water content of the common soil can meet the water requirement required by the germination of the thatch. Most desirably, the seeds are sown before raining, the second day or the third day after the seeds are sown, the germination rate is high, and the natural germination effect is good.

The drought resistance of the cymbopogon citratus seeds is very strong, after the seeds are sowed and covered with soil in 9 and 10 months, the seeds can continue to sleep if the soil moisture content is poor, and the seeds can normally sprout when the soil moisture content is improved and the soil temperature is proper, so that the influence is small.

If necessary, soil moisture is needed to be built in time.

In the S5 provided by the embodiment of the application, the seedling management method includes:

(1) After the spring festival of the second year after sowing, the quick-acting nitrogenous fertilizer is applied for 10-15 kg/mu in a rainy day. Because the growth density of the festuca arundinacea is high, nitrogen nutrient is provided by topdressing, the festuca arundinacea is utilized to grow quickly, the tillering number and the growth height of the festuca arundinacea are increased, the amount of raw grass is increased, the ground is covered as soon as possible, the festuca arundinacea is promoted to fall easily, and other weeds are prevented from growing.

(2) In order to reduce or avoid the water and fertilizer contention with fruit trees caused by grass growing or shorten the competition time, and quickly supplement soil nutrients, the additional fertilizer consumption of the thatch is increased to 20-30 kg/mu in the second round (i.e. the third year) of spring of grass growing. The recovery to the common 10-15 kg/mu is carried out in the following years.

(3) The orchard management operation can be carried out at any time after the thatch seeds fall to the ground (are sown), and the problem of damage to the thatch due to rolling, treading and the like caused by mechanical and human walking is avoided. In the growing process of the thatch, when the conventional operations such as fertilizer spraying, medicines, plant growth regulators and the like are carried out on the orchard, the adverse effect of the field operations on the thatch is not worry.

(4) When the thatch is nine mature, part of the thatch is selectively harvested according to the soil moisture content, and then the thatch is covered in an orchard without the thatch or a place with non-ideal seedling emergence in the current year, and the thatch is properly covered with soil and compacted, so that smooth seedling emergence is ensured, and the cost is effectively reduced.

(5) For a few intractable weeds such as pokeberry, annual fleabane herb, phyllanthus emblica and the like which still grow upright after the fescue falls down, the weeds are removed as early as possible before blooming and seed scattering.

(6) In the mature seventh month and the eighth month, even when the temperature and the humidity are right, the seeds are in contact with the ground for sprouting and growing, but under the stress of high temperature and high humidity, the seeds cannot grow normally and die gradually, and the phenomenon is normal.

(7) The method is characterized in that ground rotary tillage (or ditching deep burying, rotary tillage (or deep burying) of organic materials such as plant straw and leaves accumulated on the ground is carried out every 3-4 years, which is beneficial to better emergence of the thatch in the next year, and the phenomenon that the ground is exposed due to natural gathering of thatch individuals can be prevented, the rotary tillage depth is 5-8 cm, the ditching depth is 25-35 cm, the working time is 8-9 late months, and rotary tillage operation cannot be carried out after 10 months.

The scheme provides a planting method for interplanting festuca arundinacea in a festuca oleracea forest, which uses festuca arundinacea as a crop interplanted under the forest, combines the key points of festuca arundinacea tending management according to the growth rule and the cultivation characteristic of the festuca arundinacea, systematically and scientifically carries out the second round from soil preparation, sowing, fertilization, management and withering to the next year, scientifically guides and manages the festuca arundinacea, utilizes the characteristic of covering the festuca arundinacea after natural lodging, grows grass and suppresses the grass, enhances the water-retaining and heat-preserving properties of the soil of a base, promotes the ecological and organic cultivation of economic forests, and improves the quality of fruits.

The festuca arundinacea belongs to annual gramineae plants in cold seasons, and is planted in late 9 months, starts to grow after the middle 10 months, stops growing until 12 months, crosses cold winter like wheat seedlings, starts to grow at the bottom of 2 months in the next year, and can improve the green effect of forest lands in winter; after summer, the soil is dead and lodged together with the root system, the thickness of the dead grass is about 7 cm, the soil moisture content is kept, the water loss and soil erosion are prevented, the soil is decomposed and thinned, the soil organic matters are supplemented, and the physicochemical properties of the soil are improved; the grass seeds can naturally fall off after being ripe, naturally germinate for 9 months, and are free from tillage and sowing in the next year, and can benefit from sowing in one time for 3-4 years. The characteristics of long-term weed inhibition and natural lodging without mowing and covering of the festuca arundinacea are that other grass seeds cannot be provided, and the grass inhibition and soil improvement are realized on the basis of saving labor cost. And the thatch (Vulpiammouros) is naturally distributed in the province (Zhejiang province) and has no problem of biological hazard.

There are two modes of artificial planting of thatch in economic forests, namely whole-garden grass growing and interline grass growing. The grass growing mode is adopted, and the grass growing mode is combined with the actual production and is flexibly applied. The whole-garden grass is generally suitable for high-yield orchards with sufficient water resources, flat terrain and rich soil. The method is suitable for the application of inter-row grass growing mode in the economic forest orchards with shortage of water resources, thin soil layer and low fertility.

In order to solve the problems of soil degradation such as degradation, acidification, hardening, serious water and soil loss and the like of planting soil organic matters generated in the long-term cultivation process of forest lands such as oil tea forests and the like, the applicant conducts a great deal of investigation and research, discovers and surveys 28 thatch community-like lands, and has an altitude of 20-1486 meters, and relates to various different site environments such as coastal lands, mountain plains, barren beach and gullies and the like. Through soil detection and community investigation, analysis and statistics are carried out to judge that: (1) the growth of the thatch has low requirement on woodland soil, and can grow in extreme environments; (2) the festuca arundinacea can improve the organic matter content of the woodland soil and increase the soil fertility; (3) the planting of the festuca arundinacea is promoted in the whole province without considering geographical climate factors, and the hidden danger of biological invasion does not exist.

The comparison test is carried out by planting the festuca arundinacea under the conditions of tea-oil camellia, chinese torreya and peach shape Li Lin, and the test shows that: the artificial planting of the thatch has positive influence on the improvement of the physicochemical properties of the forest land soil, the content of nutrient elements in the soil is comprehensively improved, the soil structure is improved, the regulation and control capability of the temperature and the humidity of the soil is enhanced, and the effect tends to be better when the time is longer. The first year 4 and 5 months of planting the thatch, the requirement for soil moisture increases or water can be striven for with economic tree species due to flowering, fruiting, lodging and death of the thatch.

The application is further described in connection with experimental data as follows:

after the festuca arundinacea, the torreya grandis and the peach-shaped Li Lin are planted for one year, compared with the traditional clear cultivation industry:

1. the average temperature of the soil in whole year month is improved by-1.6 to 0.53 ℃, the lowest temperature in whole year month is improved by 0.9 to 6.0 ℃, the highest temperature in whole year month is reduced by 11.4 to-1.4 ℃, the temperature is reduced by 0.4 to 11.4 ℃ in summer and the temperature is increased in winter, and the temperature is obviously reduced as the temperature is higher; the murine Mao Zubi white clover group has better effects on improving the annual average temperature and the annual minimum temperature of soil and reducing the highest temperature in summer, and has larger influence on reducing the temperature difference amplitude. The time for the highest and lowest temperature of the soil is 1-2 hours.

2. The average annual water content of the soil is improved by 9.6 to 99.3 percent, the lowest water content of the soil is improved by 17.1 to 118.2 percent, and the highest water content of the soil is improved by 16.2 to 71.6 percent by planting the thatch; the murine Mao Zubi white clover group has obvious effect on improving the water content of soil.

3. The effect of the 4-5 month mice Mao Zubi white clover group on soil moisture consumption is increased, and the lowest and highest water contents are obviously reduced; the highest temperature reduction for 7-9 months is better than that of the white clover group.

4. The organic matter content of the soil surface layer of 0-20 cm is improved by 0.35-3.2 times; the total phosphorus content of the soil is reduced by 42.86-79.20%, and the rapid phosphorus content of the soil is improved by 50.00-189.47%; the total potassium is improved by 2.05 to 3.33 times and the fast potassium is improved by 1.21 to 5.07 times; the total nitrogen is improved by 45.45 to 135.29 percent, and the quick nitrogen is improved by 43.37 to 109.68 percent; the PH value of the soil is improved by 0.1 to 1.0, the total porosity of the soil is 2.06 to 6.19 percent, and the volume weight of the soil is reduced by 0.03 to 0.20g/cm < 3 >.

5. The effect of the murine Mao Zubi white clover group on the reduction of the total phosphorus content and the improvement of the rapid phosphorus content of the soil is more obvious, which shows that the murine Mao Zubi white clover group can fully improve the effective conversion, absorption and utilization of phosphorus elements. Comprehensive analysis shows that the murine Mao Zubi white clover group has more positive effect on improving the physicochemical properties of the soil of the torreya woodland.

Further research on the effect of the festuca arundinacea planted in the oil tea forest on soil fixation and fertilizer preservation is carried out, and preliminary reveals that the festuca arundinacea planted in the oil tea forest plays an important role in reducing the erosion of the surface layer of the soil and the loss of soil nutrients, and after one year of festuca arundinacea planted in the oil tea forest Lin Zhi is compared with the traditional clear farming:

1. soil erosion, conventional cultivation methods cause soil loss of 0.73 tons/mu.year, the planted thatch is 0.15 tons/mu.year, and the soil loss is reduced by 79.31%.

2. Nutrient loss, compared with 25.55 kg/mu of the control group of the conventional farming method, 8.47 kg/mu of the festuca arundinacea group is lost, 66.87% of nutrients (total nitrogen, total phosphorus, total potassium and organic matters) carried by eroded soil are reduced, wherein 69.01% of nitrogen elements (comprising hydrolyzed nitrogen 70.34%), 95.0% of phosphorus elements (comprising fast phosphorus 68.97%), 54.74% of potassium elements (comprising fast potassium 63.92%), 70.31% of organic matters are reduced, and 17.08 kg/mu of the festuca arundinacea group is calculated.

The practice of planting the festuca arundinacea under the tea-oil trees, the torreya grandis and the peach shape Li Lin proves that the festuca arundinacea is suitable for the mountain soil condition growth, does not hinder the production operation, has green effect and greening quality, and has positive significance of greening the forest in winter. The green period of up to 6-7 months is up to make up for the green empty window of the fallen leaf economic forest stand such as peach-shaped plums in the period from the whole fallen leaves to the next year of leaf placement, the surface light baldness of the under-forest land caused by long-term cultivation is changed, and the green plant of the fallen leaf forest phase is restored.

Through the experimental study, a set of complete cultivation technology under the mouse thatch is formed: the technical research of interplanting the festuca arundinacea in different economic forests such as oil tea forests, torreya forests and peach shaped plums is completed, and a set of complete production technology is formed through main production links such as land leveling, sowing on time, selecting a sowing mode according to soil fertility, mixing fertilizer (soil) sowing, controlling soil moisture, ensuring seed to enter soil, fertilizing after spring, controlling weed invasion, reseeding in the coming year and the like.
