Embodiment 1

[0013] Nutrient solution use: before the hard core period, N: 60ppm comprehensive liquid fertilizer, 2 times a week, the amount of nutrient solution for each watering is 60 liters (kg) of nutrient solution per cubic meter of root volume. After the hard core period, the concentration of the nutrient solution was reduced to 20ppm, and the application amount and application times remained unchanged.

[0014] Irrigation water use: from the germination period to the fruit setting period, maintaining a relatively dry soil moisture condition is conducive to promoting the occurrence of new roots, easing the growth potential of early shoots, and promoting fruit setting; after fruit setting to the fruit softening period, maintain a relative Rich water content is conducive to maintaining the vitality of new shoots and promoting the expansion of fruit grains; after the fruit grains soften to the mature harvesting period, the soil must be kept relatively dry, which can promote the accumulat...

Embodiment 2

[0016] Fertilization method: Use decomposed bean cake high-nitrogen organic fertilizer, apply about 1.0-1.5 kg per cubic meter of root zone soil, before germination (rain-shelter cultivation around March 20) and after harvest (rain-cultivated cultivation at 8 In the middle and late month) divided into 2 times.

[0017] Irrigation water use: the starting point of irrigation before germination is 158.5kPa, the starting point of irrigation from germination to fruit grain softening period is 31.5kPa; thereafter 158.5kPa, the irrigation volume is 60L / m 3 .

[0018] The above-mentioned implementation effects of the present invention are mainly reflected in: 1) good coloring and high quality of the fruit; 2) slow growth of new shoots, good flower formation, early production, high yield and quick effect; 3) increasing the purpose and controllability of fertilization , to avoid fertilizer delay and nutrient loss; 4) The root system has a high density, and the regulation of water is ea...

Abstract

A method for applying the fertilizer and water to grapevine to limit its root domain includes the method A for applying nutritive liquid and the method B for irrigation. The said method A features that the integrated high-concentrating liquid fertilizer is applied twice per week before the kernel hardening period and the low-concentration one is then applied after the kernel hardening period. Said method B features that the irrigation standard is that the water potential in soil is 158.5 kPa before germination, 31.5 kPa from germination to the fruit softening period, and 158.5 kPa in later phase.

Description

technical field [0001] The invention relates to a method in the technical field of cultivation of agricultural and forestry crops, in particular to a method for using fertilizer and water in restricted cultivation of grape roots. Background technique [0002] It is generally believed that fruit trees are perennial crops, and only by cultivating a strong and tall tree structure can they have high yield and longevity. Therefore, the concepts of "deep roots and big trees" and "deep plowing and more fertilization" have dominated people for a long time. However, this traditional method has at least the following disadvantages: ① In order to cultivate tall trees, it is necessary to form a specific tree shape through heavy pruning, which will cause young trees to grow excessively, with few flowers, low yield and poor quality; ② deep plowing Fertilization in a wide area makes the root system widely distributed, and it is difficult to judge the exact location of the root system. Fer...
