Method for cultivating early-harvesting high-quality high-yield lemon trees

Abstract

The invention relates to a method for cultivating early-harvesting high-quality high-yield lemon trees, which comprises the following steps: field planting of tree seedlings; tip-promotion fertilization after the tree seedlings survive; applying compound fertilizer to roots according to the amount of between 20 and 30 grams per plant before sprouting; pinching when young sprouts grow to form 4 to8 pieces of leaves, and pinching again when the young sprouts after the pinching have 2 to 3 new sprouts; and continuously pinching until the tree seedlings grow into a fruit high-yield period. The method can effectively keep the relative balance of reproductive growth and vegetation growth of the young lemon trees, cultivate branch tip groups with fewer tree crown skeleton branch levels and appropriate lengths, shorten the vegetation growth time, and can blossom and grow fruits in 8 to 10 months after the field planting; and the year yield can reach 100 to 300 kilograms per mou, the second year yield can reach between 1,000 and 1,500 kilograms per mou, the fourth year yield can reach between 4,000 and 5,000 kilograms per mou, the harvest time can be advanced by 2 to 3 years compared withthat of the traditional cultivation method, and the production investment can be reduced by more than 30 percent.

Description

technical field

[0001] The invention relates to a method for cultivating a lemon tree type, in particular to a method for cultivating a lemon tree type with early fruiting, high quality and high yield, and belongs to the technical field of plant cultivation. Background technique

[0002] The lemon tree grows vigorously, with many branch shoots and a large amount of shoots, so pruning and shaping are often needed. Traditional pruning and shaping methods are not only labor-intensive, time-consuming, pesticide and fertilizer-intensive, but also tend to cause strong centrifugal growth of branches, making lemon plants tall, vegetative growth and reproductive growth imbalance, resulting in difficulty in fruiting and low fruit setting rate ( The average yield per unit area is lower than 200--300kg / mu), the quality of fresh fruit is poor, and the management cost is high; secondly, the saplings will end up prematurely and senile. It is difficult to bag fresh lemon fruit, and the fru...

Examples

Embodiment 1

[0021] a, the lemon seedlings are planted with a row spacing of 3 meters and a plant spacing of 2 meters, and 111 plants are planted per mu;

[0022] b. After planting and surviving, fertilize according to conventional methods and conventional dosages to promote the growth of shoots;

[0023] c. Before pulling out the shoots, apply N15 / P15 / K15 compound fertilizer around the rhizosphere in the amount of 10g / plant, combined with irrigation or when the soil is wet. There is a tender stem of 0.8cm between the remaining last leaves, and the young shoots in the wrong position are erased simultaneously, such as figure 1 ;

[0024] d. Apply N15 / P15 / K15 compound fertilizer around the rhizosphere at an amount of 15g / plant, combined with irrigation or when the soil is moist, before the young shoots after pinching are taken out, and 3 new shoots are formed when the young shoots are drawn. And when each new shoot grows 6 leaves, pinch the heart again. When pinching the heart, control the...

Embodiment 2

[0027] a, the lemon seedlings are planted with a row spacing of 4 meters and a plant spacing of 3 meters, and 55 plants are planted per mu;

[0028] b. After planting and surviving, fertilize according to conventional methods and conventional dosages to promote the growth of shoots;

[0029] c. Before pulling out the shoots, apply N21 / P9 / K15 compound fertilizer around the rhizosphere in the amount of 20g / plant, combined with irrigation or when the soil is moist. There is a tender stem of 0.4cm between the remaining last leaves, and the young shoots that are inappropriate for the birth position are erased simultaneously, such as figure 1 ;

[0030] d. Apply N21 / P9 / K15 compound fertilizer around the rhizosphere in an amount of 30g / plant before the young shoots after pinching are combined with irrigation or soil moistening. When the young shoots grow, 3 new shoots are formed. And when each new shoot grows 6 leaves, pinch the heart again. When pinching the heart, control the ten...
