Abstract
Description
Technical Field
[0001] The invention relates to the technical field of seed breeding, and more particularly to a method for breeding wild Stipa grandis seeds. Background Art
[0002] Stipa grandis is a densely clumping perennial herb in the Poaceae family and genus Stipa. Its culms can reach 100 cm in height, with persistent, withered leaf sheaths at the base that are rough or smooth with age. Its basal leaves are obtuse, lanceolate, and have ciliate margins. The leaves are longitudinally rolled, needle-like, slightly hairy above and smooth beneath. The panicle inflorescence is enclosed within the leaf sheath, with thin, upright branches. Its spikelets are pointed lanceolate, with a filiform tip. The lemma has short hairs at the apical joint. The awns are twisted and slightly rough, with curled awns. The palea and lemma are equal in length. Flowering and fruiting occur from May to August. However, existing methods for seed propagation of wild Stipa grandis lack prior analysis of site selection and surrounding information, meaning no field selection is performed, which hinders seed propagation. Summary of the Invention

[0007] After the breeding fields were tilled, Stipa grandis seeds were sown;
[0008] After sowing in the breeding field, the growth conditions of the Stipa grandis seedlings in the breeding field are obtained, and the growth conditions of the Stipa grandis seedlings in the breeding field are processed and analyzed to obtain the interference value;
[0009] The interference value was used to interfere with the Stipa grandis seedlings in the breeding field;

[0027] Compare the tillage value GZZ with the preset tillage threshold GZY:
[0028] If the tillage value GZZ ≥ the preset tillage threshold GZY, it means that the tillage of the breeding field is qualified;

BRIEF DESCRIPTION OF THE DRAWINGS
[0040] Figure 1 The present invention provides a flow chart of a method for breeding wild Stipa grandis seeds. DETAILED DESCRIPTION
[0041] Reference Figure 1 shown.
[0042] The following is a further description of an embodiment of a method for breeding wild Stipa grandis seeds of the present invention.
[0043] A method for breeding wild Stipa grandis seeds, comprising the following steps:
[0044] Obtaining field information of a site selected before seed propagation of Stipa grandis and surrounding information of the site; obtaining a screening value by processing and analyzing the field information of the site selected before seed propagation of Stipa grandis and surrounding information of the site, and marking the site that meets the screening value as a breeding field;
[0045] After the breeding fields were tilled, Stipa grandis seeds were sown;
[0046] After sowing in the breeding field, the growth conditions of the Stipa grandis seedlings in the breeding field are obtained, and the growth conditions of the Stipa grandis seedlings in the breeding field are processed and analyzed to obtain the interference value;
[0047] The interference value was used to interfere with the Stipa grandis seedlings in the breeding field;
[0048] The Stipa grandis seeds in the breeding field are harvested when they are mature.
[0049] This application processes and analyzes the field information of the site selected before Stipa grandis seed breeding and the surrounding information of the selected site, that is, the site selection is performed before Stipa grandis seed breeding, and the plots suitable for Stipa grandis seed breeding are marked as breeding fields. This application also processes and analyzes the growth conditions of Stipa grandis seedlings inside the breeding fields. When abnormal conditions occur during the growth of Stipa grandis seedlings, the staff is promptly notified to intervene in the Stipa grandis seedlings inside the breeding fields, that is, to ensure the normal growth of the Stipa grandis seedlings, and to harvest the Stipa grandis seeds in the breeding fields when they are mature.
[0050] The field information of the selected site includes the type of crops grown before the selected site, the soil layer below the surface, and the groundwater level;
[0051] It should be noted that when selecting a site before breeding Stipa grandis seeds, it is best to have a bean crop as the previous crop, and there should be no clay layer, calcareous layer or other hard layer below the surface soil, good irrigation and drainage conditions, and the groundwater level should be below 1.5m.
[0052] The surrounding information of the selected site includes the distance information of other flowering grasses around the selected site.
[0053] It should be noted that the seed fields of other grasses, especially Stipa, with similar flowering periods should be spaced 500m-800m apart to prevent mixed hybridization.
[0054] The information of the crop species before the selected site is obtained by taking and marking the crop species value XZZ before the selected site;
[0055] It should be noted that if the best previous crop when selecting the site before Stipa grandis seed breeding is a legume crop, the previous crop type value XZZ of the selected site is 6; if the best previous crop when selecting the site before Stipa grandis seed breeding is not a legume crop, the previous crop type value XZZ of the selected site is 0.
[0056] The information of the soil layer below the surface soil is taken and marked to obtain the soil layer value BTZ below the surface soil;
[0057] It should be noted that if there is no clay layer, calcareous layer or other hard layer below the topsoil, the BTZ value of the soil layer below the topsoil is 6. If there is a clay layer, calcareous layer or other hard layer below the topsoil, the BTZ value of the soil layer below the topsoil is 0.
[0058] The groundwater level information is taken and marked to obtain the groundwater level value TXS;
[0059] It should be noted that if the groundwater level is below 1.5m, the groundwater level value TXS is 6; if the groundwater level is not below 1.5m, the groundwater level value TXS is 0.
[0060] The distance information of other flowering grasses around the selected site is obtained and marked to obtain the distance value TMJ of other flowering grasses.
[0061] It should be noted that if the distance between seed fields of other grasses with similar flowering periods, especially Stipa, is greater than 500m, the distance value TMJ of grasses with other flowering periods is 6; if the distance between seed fields of other grasses with similar flowering periods, especially Stipa, is less than 500m, the distance value TMJ of grasses with other flowering periods is 0.
[0062] The screening value SXZ is calculated by the screening function SXZ = a1×XZZ+a2×BTZ+a3×TXS+a4×TMJ, where a1, a2, a3, and a4 are all impact factors and are greater than zero;
[0063] Here, the values of a1, a2, a3, and a4 are all set to 1. When the value of the previous crop type XZZ in the selected site is 6, the value of the soil layer below the topsoil BTZ is 6, the value of the groundwater level TXS is 6, and the value of the distance value TMJ to other flowering grasses is 6, the screening value SXZ is calculated to be 24 through the screening function SXZ = a1×XZZ+a2×BTZ+a3×TXS+a4×TMJ; when the value of the previous crop type XZZ in the selected site is 0, the value of the soil layer below the topsoil BTZ is 0, the value of the groundwater level TXS is 6, and the value of the distance value TMJ to other flowering grasses is 6, the screening value SXZ is calculated to be 12 through the screening function SXZ = a1×XZZ+a2×BTZ+a3×TXS+a4×TMJ.
[0064] Compare the screening value SXZ with the preset screening threshold SXY:
[0065] If the screening value SXZ ≥ the preset screening threshold SXY, the selected field is marked as a breeding field;
[0066] If the screening value SXZ is less than the preset screening threshold SXY, the selected field will not be marked as a breeding field.
[0067] Here, the preset screening threshold SXY is set to 24. When the screening value SXZ is 24, since the screening value SXZ = the preset screening threshold SXY, the selected site is marked as a breeding field. When the screening value SXZ is 12, since the screening value SXZ < the preset screening threshold SXY, the selected site is not marked as a breeding field.
[0068] When the breeding fields are cultivated, plowing and irrigation treatments are performed;
[0069] Obtain information on root residues and weeds in the breeding fields when the fields are tilled;
[0070] The average soil moisture content information at 0–25 cm was obtained during irrigation treatments during tillage treatments in the breeding fields;
[0071] It should be noted that before breeding Stipa grandis seeds, the breeding fields need to be plowed, that is, the soil needs to be broken up by harrowing, and the residual roots, weeds and garbage in the breeding fields need to be cleaned up; and the breeding fields need to be irrigated so that the soil moisture content of 0-25cm before sowing is not less than 13%.
[0072] The residual roots and weeds in the breeding field are valued and marked to obtain the debris value ZWZ;
[0073] It should be noted that, since the breeding fields need to be cultivated before breeding Stipa grandis seeds, so as to remove the residual roots and weeds inside the breeding fields, when there are no residual roots and weeds inside the breeding fields, the debris value ZWZ is 3; when there are residual roots and weeds inside the breeding fields, the debris value ZWZ is 0.
[0074] The average soil moisture content information of 0-25 cm is taken and marked to obtain the moisture content value HSL;
[0075] It should be noted that if the average soil moisture content of 0-25 cm is not less than 13%, the HSL value is 3; if the average soil moisture content of 0-25 cm is less than 13%, the HSL value is 0.
[0076] The tillage value GZZ is calculated by the tillage function GZZ = b1 × ZWZ + b2 × HSL, where b1 and b2 are both influencing factors and are greater than zero;
[0077] It should be noted that the values of b1 and b2 are set to 1 here. When the debris value ZWZ is 3 and the moisture content value HSL is 3, the tillage value GZZ calculated by the tillage function GZZ = b1 × ZWZ + b2 × HSL is 6; when the debris value ZWZ is 0 and the moisture content value HSL is 3, the tillage value GZZ calculated by the tillage function GZZ = b1 × ZWZ + b2 × HSL is 3.
[0078] Compare the tillage value GZZ with the preset tillage threshold GZY:
[0079] If the tillage value GZZ ≥ the preset tillage threshold GZY, it means that the tillage of the breeding field is qualified;
[0080] If the tillage value GZZ is less than the preset tillage threshold GZY, it means that the tillage of the breeding field is unqualified.
[0081] It should be noted that the preset tillage threshold GZY is set to 6 here. When the tillage value GZZ is 6, since the tillage value GZZ = the preset tillage threshold GZY, it means that the tillage of the breeding field is qualified. When the tillage value GZZ is 3, since the tillage value GZZ < the preset tillage threshold GZY, it means that the tillage of the breeding field is unqualified.
[0082] The growth conditions of Stipa grandis seedlings in the breeding field include weed information, insect pest information and foreign seedling information in the breeding field.
[0083] After the Stipa grandis seeds are propagated, weeds may grow in the breeding fields, pests may grow on the Stipa grandis seedlings, and weak seedlings, diseased seedlings, and mixed seedlings may appear. If these situations occur in the breeding fields, the staff needs to be notified to deal with them. That is, if weeds grow in the breeding fields, the staff needs to be reminded to carry out weeding. If pests grow on the Stipa grandis seedlings, the staff needs to be notified to carry out pest control on the Stipa grandis seedlings. If weak seedlings, diseased seedlings, and mixed seedlings appear, the staff needs to be notified to pull out the weak, diseased, and mixed seedlings.
[0084] The weed information inside the breeding field is obtained by taking values and marking the weed value ZCC;
[0085] It should be noted that if weeds grow inside the breeding field, the weed value ZCC is 3, and if weeds do not grow inside the breeding field, the weed value ZCC is 0.
[0086] The pest information inside the breeding field is collected and marked to obtain the pest value CHZ;
[0087] It should be noted that if pests grow on the Stipa grandis seedlings, the pest value CHZ is 3, and if no pests grow on the Stipa grandis seedlings, the pest value CHZ is 0.
[0088] The information of foreign seedlings in the breeding field is taken and marked to obtain the foreign seedling value YMZ.
[0089] It should be noted that if weak seedlings, diseased seedlings, or mixed seedlings appear in the breeding field, the value of the mixed seedling value YMZ is 3. If there are no weak seedlings, diseased seedlings, or mixed seedlings in the breeding field, the value of the mixed seedling value YMZ is 0.
[0090] The interference value GSZ is calculated by the interference function GSZ=c1×ZCC+c2×CHZ+c3×YMZ, where c1, c2 and c3 are influencing factors and are greater than zero.
[0091] It should be noted that the values of c1, c2 and c3 are all set to 1 here. When the weed value ZCC is 3, the pest value CHZ is 3 and the seedling value YMZ is 3, the interference value GSZ calculated by the interference function GSZ = c1×ZCC+c2×CHZ+c3×YMZ is 9. When the weed value ZCC is 0, the pest value CHZ is 0 and the seedling value YMZ is 3, the interference value GSZ calculated by the interference function GSZ = c1×ZCC+c2×CHZ+c3×YMZ is 3.
[0092] Compare the interference value GSZ with the predefined interference threshold GSY:
[0093] If the interference value GSZ ≥ the preset interference threshold GSY, the staff will be reminded to perform interference treatment on the Stipa grandis seedlings in the breeding field;
[0094] If the interference value GSZ is less than the preset interference threshold GSY, the staff will not be reminded to perform interference processing on the Stipa grandis seedlings inside the breeding field.
[0095] Here, the preset interference threshold GSY is set to 9. When the interference value GSZ is 9, since the interference value GSZ is greater than the preset interference threshold GSY, the staff is reminded to perform interference treatment on the Stipa grandis seedlings inside the breeding field. When the interference value GSZ is 3, since the interference value GSZ is less than the preset interference threshold GSY, the staff is not reminded to perform interference treatment on the Stipa grandis seedlings inside the breeding field.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
