The invention discloses an actinidia chinensis planting method. The method includes the first step of address selection and soil preparation, the second step of greenhouse building, the third step of planting, the fourth step of shaping and pruning, the fifth step of fertilization, the sixth step of pesticide application, the seventh step of irrigation and drainage, the eighth step of flower and fruit management, the ninth step of disease and insect prevention, the tenth step of weeding, the eleventh step of fruit harvesting and the twelfth step of pruning. By means of garden plot selection, pressure of actinidia chinensis on soil is reduced, farmyard organic fertilizer is applied so as to provide rich nutrients for actinidia chinensis, mineral content in the planted actinidia chinensis is high, and no chemical residues exist in the planting process. Soil is reasonably used, development of branches and leaves and development of fruits are both taken into consideration, and rooting and survival of actinidia chinensis trees are benefited due to the diameter and the depth of planting pits. In the pollen pollination stage, the dilution dropwise application method is adopted, the pollination success rate is increased, and the yield of single actinidia chinensis plants is increased.

The invention discloses a paddy planting method. The paddy planting method provided by the invention has strong pertinence; targeted fertilization in each growing period is carried out; the germination rate of paddy seeds can be greatly improved through treatment of the paddy seeds, the germination rate can reach 99.8%, and the paddy growth is accelerated; in a tillering stage, the tillering number is increased through a tillering fertilizer; the pollination success rate can be improved through the application of a flowering-stage fertilizer in a flowering stage; the grouting rate is greatly improved through the top dressing with a filling fertilizer and a foliar fertilizer, so that the filling rate is greatly increased, and paddy grains are fuller; and the used fertilizer can obviously improve soil. The paddy planted by the method has the advantages of high setting rate, uniform growth and full grains, and the paddy yield is improved.

The invention belongs to the technical field of hybridization breeding and in particular relates to a prunus salicina hybridization breeding method. The method provided by the invention is realized through the following steps: (1) during a revealing period, selecting female parent trees to be hybridized, wherein 2 to 3 plants of each variety are selected; erecting a shed frame capable of completely covering the female parent trees at the peripheries of tree crowns; (2) covering the shed frame with a shed cover and compacting the lower part with soil; (3) shearing flowering branches in a flowering period from male parent trees and inserting the flowering branches into a bottle filled with water; hanging the flowering branches to the upper parts of inner parts of the tree crowns of the female parent trees respectively; (4) putting one box of bees into the shed 3 days before flowering, and pollinating. The method provided by the invention is simple to operate and can be finished without a pollination tool, so that the method is suitable for large-batch hybridization; the pollination success rate is high and the hybridization success rate is high.

The invention discloses fertilizer for cultivation of ratooning rice. The fertilizer comprises seedling stage fertilizer, grouting fertilizer, flowering stage fertilizer, tillering fertilizer, foliagefertilizer and planting base fertilizer; fertilizer is applied pertinently in each growing stage, so that the germination stage can be shortened, the growth of the rice can be accelerated, the stressresistance of the rice can be improved, the cycle from germination to flowering can be shortened, and the flowering stage and the fruiting stage can be prolonged; the tillering number is increased through the tillering fertilizer in the tillering stage; the flowering stage fertilizer is applied in the flowering stage, to increase the pollination success rate; the grouting rate is greatly increased by dressing the grouting fertilizer and the foliage fertilizer in the grouting stage, so that the yield is increased and the rice granules are fuller.

The invention relates to the field of technologies for planting crops, in particular to a method for planting paddy rice. The method particularly includes selecting paddy rice seeds; applying rice seedling stage fertilizers; carrying out transplanting; applying tillering fertilizers; applying flowering stage fertilizers; applying grain filling fertilizers; applying foliar fertilizers; harvesting the paddy rice. The method for planting the paddy rice has the advantages that the method is high in pertinence, and the fertilizers are pertinently applied at various growth stages; pretreatment on the paddy rice seeds is combined with treatment by the aid of seed soaking liquid, accordingly, the germination rate of the paddy rice seeds can be greatly increased and can reach 99.8%, and growth of the paddy rice can be accelerated; the tillering numbers can be increased at tillering stages by the aid of the tillering fertilizers; the flowering stage fertilizers are applied at flowering stages, and accordingly the pollination success rate can be increased; the grain filling fertilizers and the foliar fertilizers are dressed at grain filling stages, accordingly, the grain filling rate can be greatly increased, paddy rice grains are plump, and soil can be obviously improved by the applied fertilizers; the paddy rice planted by the aid of the method is high in setting rate and uniform in growth vigor, the grains are plump, and the yield of the paddy rice can be increased.

A planting method for improving cucumber output relates to the field of planting, and includes the following steps: 1) land selection; 2) seedling growing; 3) germination; 4) transplanting; 5) growth of cucumber seedlings; and 6) fruiting. The planting method of the invention can significantly increase the number of female flowers, assures pollination rate, increases the rate of fruit setting, and improves plant stress resistance and the physiological property. The cultivated cucumber has high output, good taste, good appearance, and better market competitiveness.

The invention discloses a plantation method for raising the yield of red core kiwi fruits. The plantation method includes the following steps: (1) selecting a site, and preparing land; (2) putting upa shed; (3) performing plantation; (4) shaping and trimming seedlings of the kiwi fruits; (5) applying fertilizer; (6) applying farm chemicals; (7) irrigating and draining the soil; (8) performing flower and fruit management; (9) controlling diseases and pests; (10) performing weeding; (11) harvesting the fruits; and (12) trimming the seedlings. According to the plantation method, the pressure onthe soil of the red core kiwi fruits is reduced through garden selection; rich nutrients are provided for the red core kiwi fruits through application of farm organic fertilizer; the mineral content of planted red core kiwi fruits is high, and chemical residues are not produced during a planting process; branches and leaves and the fruits are developed while soil is reasonably utilized, and the diameter and depth of planting holes facilitate rooting and survival of kiwi fruit trees; and the pollination success rate is improved by employing a dilution point pollination method in a pollen pollinating stage, thereby increasing the yield per plant of the red core kiwi fruits.
