The invention discloses a method for planting walnut trees, and belongs to the technical field of walnut
tree planting. The method includes the steps that 1,
land preparation is performed, wherein a sandy
loam land which is deep in soil layer and loose in
soil texture is selected as a planting land, the pH value of soil is 6.8-8.2, the land is subjected to deep ploughing, then a nutritional matrixis applied, the soil is raked to be even, a
seedling culturing
bed is obtained through excavation, and the nutritional matrix comprises, by weight, 10-15 parts of turf, 20-25 parts of
cow dung, 17-23parts of fishbone dust, 30-38 parts of wheat
bran and 15-20 parts of
egg white; 2, seeds are treated; 3, seeding is performed; 4,
transplanting is performed, wherein planting pits are dug in the planting land, the spacing between the adjacent planting pits is 30-40 cm, then a cultivation matrix with the thickness of 5-8 cm is laid in each planting pit, walnut tree seedlings are not transplanted until the walnut tree seedlings grow to 35-40 cm, and the cultivation matrix comprises, by weight, 10-15 parts of
earthworm cast, 5-7 parts of
ammonium nitrate, 8-11 parts of black soil and 6-9 parts of
straw. By the adoption of the method, the plumpness of walnuts can be effectively improved, and the
oil content of the walnuts can be effectively increased.
