Embodiment 1

[0017] A kind of upland sweet potato watermelon three-dimensional cultivation method comprises the following steps:

[0018] 1) Deep plow the red soil soil to 20 cm in mid-October;

[0019] 2) In the middle and late March, when the soil moisture content is 65%, the ridges are rowed according to the conventional method, and nitrophosphate fertilizer is applied at 20 kg / mu in the furrow, and potassium sulfate fertilizer is applied at 20 kg / mu on both sides of the furrow, and covered Microfilm;

[0020] 3) In early April, watermelons were planted in the furrows at a plant spacing of 40 cm;

[0021] 4) In late April, sweet potato seedlings were planted in the upper part of the ridge by rolling holes with a spacing of 23 cm. The hole diameter was 1.2 cm and the depth was 15 cm. Water and cover soil according to conventional methods.

Embodiment 2

[0023] A kind of upland sweet potato watermelon three-dimensional cultivation method comprises the following steps:

[0024] 1) Deep plow the red soil soil to 23 cm in late October;

[0025] 2) In the middle and late March, when the soil moisture content is 68%, the ridges are rowed according to the conventional method, and nitrophosphate fertilizer is applied at 22 kg / mu in the furrow, and potassium sulfate fertilizer is applied at 23 kg / mu on both sides of the furrow, and covered Microfilm;

[0026] 3) In early April, plant watermelons in the furrows at a plant spacing of 45 cm;

[0027] 4) In late April, sweet potato seedlings were planted in the upper part of the ridge by rolling holes with a spacing of 25 cm. The hole diameter was 1.4 cm and the depth was 17 cm. Water and cover soil according to conventional methods.

Embodiment 3

[0029] A kind of upland sweet potato watermelon three-dimensional cultivation method comprises the following steps:

[0030] 1) Deep plow pure sandy soil in late October to a depth of 25 cm;

[0031] 2) In the middle and late March, when the soil moisture content is 70%, the ridges are rowed according to the conventional method, and nitrophosphate fertilizer is applied at 25 kg / mu in the furrow, and potassium sulfate fertilizer is applied at 25 kg / mu on both sides of the furrow, and covered Microfilm;

[0032] 3) In early April, watermelons were planted in the furrows at a plant spacing of 50 cm;

[0033] 4) In late April, sweet potato seedlings were planted in the upper part of the ridge by rolling holes with a spacing of 26 cm. The hole diameter was 1.5 cm and the depth was 20 cm. Water and cover soil according to conventional methods.

Abstract

The invention belongs to the technical field of a crop cultivation method, in particular relates to a three-dimensional cultivation method for sweet potatoes and watermelons in a dry land, and aims to solve the problems of irrationality, high labor intensity, low yield, low land utilization rate and the like in the conventional cultivation method for sweet potatoes and watermelons in the dry land. The technical scheme of the invention comprises the following steps of: 1) deeply ploughing the land to the depth of 20-25cm in the middle of October or late October; 2) rowing and ridging according to the conventional method in middle and late March when the moisture content of soil is 65 to 70 percent, applying a nitrophosphate fertilizer in field ditches according to a ratio of 20-25kg / mu, applying a potassium sulfate fertilizer on two sides of the field ditches according to a ratio of 20-25kg / mu, and covering micro-films; 3) planting watermelons in the field ditches in early April according to the row spacing of 40-50cm; and 4) holing and planting sweet potato seedlings on the upper parts of the ridges in late April according to the row spacing of 23-26cm, and watering and covering soil according to the conventional method. The method has the advantages of high yield, low labor intensity, high land utilization rate and the like.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and in particular relates to a three-dimensional cultivation method of sweet potatoes and watermelons in dry land. Background technique [0002] Sweet potato has high nutritional value and is widely used in health food. In the existing sweet potato planting process, sweet potato seedlings grow too fast, which affects the growth of sweet potato tubers and reduces the yield of sweet potato. In view of this situation, potato farmers often need to turn seedlings frequently , artificially inhibit the growth of seedlings to ensure the yield of sweet potatoes; watermelon also has the problem of too fast growth of melon seedlings in the planting process, and at the same time, in order to ensure sufficient pollination of watermelon flowers, melon growers need to continuously press seedlings, cross forks as the watermelon seedlings grow. Although it can improve the pollination of watermelo...
