The advantages are that: inducing the chicken flock to nest on time; secondly, the feed waste can be avoided, the feed intake of the chickens reaches a peak before the chickens return to the nests at evening, and the feeding speed is high; thirdly, the chickens can be prevented from gathering at the supplementary feeding point, and the chickens are promoted to be uniformly dispersed in the whole mulberry field.

And (4) finishing the stocking under the forest at the age of 130 days to change the group, transferring the hens to an egg laying chicken house to be raised, wherein the group changing needs to be carried out at the evening, and the rest is kept as much as possible, so that the stress reaction of the chicken group is avoided, and the laying rate is prevented from being influenced.

Daily management of under-forest selenium-enriched chickens needs to be dynamically adjusted at different growth stages:

in the brooding period (from hatching to 8 weeks) of the laying hens, glucose needs to be added into drinking water to enhance the body of the laying hens, the adding amount of the glucose is 5% of the drinking amount, and the water temperature is controlled to be 16-20 ℃. Enough illumination needs to be ensured in the chick stage, and the illumination is counted for 20-23 hours within 1 week after the chick is taken out of the shell; from 2 weeks, the illumination time can be reduced to a certain extent, and the illumination time is counted for 16-13 hours; then gradually adopting natural illumination for 7-8h every day. The bulb in the henhouse is generally 2m away from the ground, and the illumination intensity is 1.5～2W/m²(ii) a The relative humidity in the phase is preferably 55-65%.

In the growing period (9 th week to 18 th week) of the laying hens, the laying hens are fed in different columns according to the male and female chickens, and the feeding density is 8-10 chickens/m 2, so that the feed consumption is managed and reduced. Meanwhile, feeding with different formula feeds according to the male and female chickens. At the age of 120 days, the hens were transferred to the hen house for feeding. During the group transfer, attention should be paid to keep quiet, and the group transfer is performed in the evening as much as possible to avoid the stress reaction of the chickens and influence the laying rate.

Feeding with feed formula of laying hens in egg laying period (more than 18 weeks), and adjusting according to egg yield of chicken to maintain nutritional requirement of chicken. In order to enhance the digestion capability of the chicken, sand can be added into the feed for pecking. Meanwhile, the temperature of the henhouse is kept at 13-24 ℃, and the illumination time is 14-16 hours (the illumination intensity is 2.5W per square), and the henhouse is kept quiet and clean.

The invention relates to a middle slope management project, which selects three slope management measures of equal-height cultivation, large cross slope, small down slope and reverse slope terraced fields.

Equal-height cultivation: the method is to plough, bed and cultivate on the slope along the same height direction to form equal height furrows and crop strips, and is a soil conservation cultivation method for preserving water and soil and improving drought resistance. Cross slope cultivation is performed along contour lines to retain and store rainwater in ravines between ridges of the contour lines or to promote drainage, thereby reducing soil erosion and runoff by impeding slope flow. Equal-height cultivation shortens the length of a slope and slows down the speed of water flow, thereby reducing runoff. The ridge net is formed on the slope, so that the infiltration capacity of the soil is improved, the runoff and the erosive power of running water are finally reduced, and the erosive power of the soil is reduced. The specific method comprises the following steps: ploughing along contour lines at the lower part of the sloping field, and turning soil downwards; then uniformly sowing fertilizer and seeds on the upper half slope of the ridge, backfilling and covering soil, then repeatedly using one plough and one plough, so as to form ridges on the empty ploughed land, forming furrows by the ploughing, and building small ridges in each furrow at intervals of 1-2 m. The height of the ridges is about 15cm, and the distance between the ridges is about 65 cm. Compared with the traditional ridge culture, the equal-height cultivation can effectively play the roles of water retention, soil retention and fertilizer retention. Can effectively reduce runoff by more than 30 percent and scouring amount by more than 60 percent, and can increase the yield of crops by more than 10 percent. Can be used for planting oil tea, flos Rosae Rugosae (tea), etc.;

Effect of two-factor Interactive items on response values

Interaction of flocculation dosage and pH

The fixed temperature is 25 ℃, and when the addition amount of the flocculating agent is 0.1-0.5g/L, pH is 5-9, the turbidity removal rate shows a trend of increasing firstly and then decreasing. Compared with the pH response curved surface, the curved surface of the flocculating agent adding amount is gentle, which shows that the flocculating agent adding amount has larger influence on the turbidity removal rate. The curve shape of the contour diagram reflects the strength of the factor interaction, the ellipse represents strong interaction, and the circle represents no interaction; the contour graphs of the flocculation adding amount and the pH are elliptic, which shows that the interaction between the flocculation adding amount and the pH is stronger and has larger influence on the turbidity removal rate, as shown in FIGS. 17-18;

interaction of flocculation dosage and temperature

When the pH is 7, the change of the flocculation adding amount curved surface is more gentle than that of the temperature curved surface, which indicates that the influence of the flocculation adding amount on the turbidity removal rate is more than the pH; the contour map of the interaction between the dosage and the temperature is approximately circular, the interaction is weak, and the influence on the turbidity removal rate is small, as shown in FIGS. 19-20;

interaction of pH and temperature

When the adding amount of the fixed flocculating agent is 0.3g/L, the pH value is 5-9, and the temperature is 15-35 ℃, the turbidity removal rate tends to increase first and then decrease, and the pH curved surface is slower than the temperature curved surface, which indicates that the pH value has a larger influence on the turbidity removal rate; the contour lines are elliptical, indicating strong pH and temperature interaction, as in fig. 21-22;

as can be seen from Table 6, mCTS @ (PGA-Fe)₃O₄) The flocculant has good flocculation effect after being repeatedly utilized for three times, the recovery rate after each flocculation can reach 85 percent, and the total recovery rate is 68.9 percent. Although the effect is reduced to some extent after each recovery, the recoverability still allows mCTS @ (PGA-Fe)₃O₄) Has certain practical application significance, and the table 6 is mCTS @ (PGA-Fe)₃O₄) The recycling effect is achieved.

TABLE 4

CTS, PAM, PAC flocculation Performance comparison

Figures 23-24 compare the results of modified chitosan (mCTS), Polyacrylamide (PAM), polyaluminum chloride (PAC) flocculation treatment simulated wastewater III. As can be seen from FIG. 23, when the addition amount is 0.3g/L, the turbidity removal rate of mCTS reaches 84.2% of the peak value; the turbidity removal rates of PAM and PAC were highest at 0.3g/L and 0.4g/L, respectively, 75.1% and 77.4%. As can be seen from FIG. 24, the COD removal rates of the three solutions are generally consistent with the increasing trend of the dosage, the COD removal rate of mCTS is the highest and reaches 73.2% of the peak value at 0.4g/L, the dosage is continuously increased, and the COD removal effect is basically unchanged. In conclusion, the modified chitosan mCTS in the three flocculating agents has better turbidity removal effect than PAM and PAC, COD removal effect is basically consistent with PAM, PAC removal effect is poor, and the use amount is higher than mCTS and PAC when higher removal rate is achieved. The improvement of flocculation effect is expected to be achieved by compounding mCTS, PAM and PAC in different proportions.

Influence of mCTS and PAM composite proportion on flocculation performance

Figures 25-26 compare the effect of different mCTS to PAM composite ratios on turbidity and COD removal efficiency of simulated wastewater III. As can be seen from fig. 25, the turbidity removal rates of both single PAM and mCTS and PAM composite flocculants varied consistently. When the composite proportion is 3g of mCTS +1g of PAM, the turbidity removal rate is higher than other four proportions and always kept at a higher level, and the highest turbidity removal rate can reach 82.4 percent. As can be seen from FIG. 26, the removal rates of the five groups of the composite flocculants for COD are basically consistent with the trend of the change of the addition amount, and the trends are that the removal rates are firstly slowly increased and then stabilized. When the composite proportion is 3g of mCTS +1g of PAM, the COD removal rate is higher than that of other four proportions and can reach 76.9 percent. By combining the removal conditions of turbidity and COD by compounding mCTS and PAM, the flocculation treatment effect is best when the compounding ratio is 3g mCTS +1g PAM. The compound coagulant system obtained by the compound proportion is named as mCTS 3-PAM.
