Abstract

The invention discloses a management method for second-season fruits of grape vines. The management method comprises the following steps: a, strictly performing a management and fertilizer application method of first-season fruits, applying compound fertilizers which is low in nitrogen, low in phosphor and high in potassium through a drop irrigation facility in budding period, spraying a seaweed fertilizer and a boron fertilizer on the leaves in a matched manner; applying potassium nitrate during a fruit expanding period through the drop irrigation facility, spraying zinc-calcium amino acid on the leaves in the matched manner, applying pure potassium sulfate during a fruit hardening period through the drop irrigation facility, and spraying phosphor-potassium amino acid on the leaves in the matched manner; b, after the first-season fruits are picked, performing much-fertilizer much-water fertigation on grape vines; c, topping when four main leaves are grown, keeping the bud of the epicormic branch at the top end, and performing bud picking on the rest epicormic branches; d, adopting a plant regulator for increasing the set of fruit when the second-season flowers at the top ends of the leaves have flower buds in batches; e, only keeping four strings of fruits for each grape vine for the second-season fruits, keeping 50-70 grapes for each string of the fruits, and fertilizing according to the normal management of the first-season fruits.

Description

A kind of vine two season fruit management method

Technical field

The invention belongs to field of agricultural cultivation, be specifically related to a kind of management method viny.

Background technology

In order to obtain good economic worth, vine two season fruit the result time and quality particularly important, two seasons fruit must ripe listing before frost by the end of November, also to ensure not affect vintage and the quality in vine coming year simultaneously.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of management method that vine two season can be allowed really ripe as early as possible.

For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of vine two season fruit management method, comprise the following steps: a. strictly carries out the management fertilizing method of the fruit first season, when bud, discharged the composite fertilizer of low nitrogen, low-phosphorous, high potassium by drip irrigation facility, blade cooperation sprays alga fertilizer and boron fertilizer; Discharge potassium nitrate at fruit expanding stage by drip irrigation facility, blade cooperation sprays the acid of zinc calcium ammonium; Discharge pure potassium sulfate in the fruit phase of firmly closing by drip irrigation facility, blade cooperation sprays the acid of phosphorus, potassium and ammonium salt base; B. the normal time of vine fruit from germinateing to plucking is probably about 110 days, and the first season, fruit was after artificial effectively management is germinateed from early March and plucked to early July, just carries out large loose water to vine and fills with and execute; Pinch when c. waiting blade to grow to 4 true leaves, the sublateral shoot being retained in top germinates, and all the other sublateral shoots do bud picking process; Repeatedly manage in this way, first time is stayed 4 true leaves to pinch and smears the tip, and second time stays 4 true leaves to pinch again, and third time stays 3 true leaves to pinch, and stays for the 4th time 2 true leaves to pinch, stays 2 true sheet leaves repeatedly to pinch later at every turn; D. when blade tip have two seasons flower bud occurs in batch time, adopt plant modifying agent carry out flower and fruit protecting; E. carry out fruit thinning, the second season, each strain vine of fruit only stayed 4 string fruits, and often string fruit only stays 50-70 grain grape, then according to the first season of normal management fertilising really.

The invention has the beneficial effects as follows: owing to strictly carrying out the management fertilizing method of the fruit first season, impel the ripe harvesting within the shortest time of the fruit first season complete, reserve time enough and really produce process as two seasons, after the fruit harvesting of one season, just carry out large loose water filling to vine to execute, tree body so just can be allowed rapidly to absorb enough nutrition, reach the object of flower forcing early, pinch when growing to 4 true leaves in blade, branch nutrient can be allowed to make bud nutrient obtain absorbing fully growing up from the backflow of blade tip advantage, thinning can ensure often to go here and there the seed output and quality of grape, thus allow two seasons fruit can ripe listing before frost by the end of November.

Embodiment

Below in conjunction with embodiment, the present invention will be described.

Vine two season fruit a management method, comprise the following steps:

A. strictly carry out the management fertilizing method of the fruit first season, when bud, discharged the composite fertilizer of low nitrogen, low-phosphorous, high potassium by drip irrigation facility, blade cooperation sprays alga fertilizer and boron fertilizer; Discharge potassium nitrate at fruit expanding stage by drip irrigation facility, blade cooperation sprays the acid of zinc calcium ammonium; Discharge pure potassium sulfate in the fruit phase of firmly closing by drip irrigation facility, blade cooperation sprays the acid of phosphorus, potassium and ammonium salt base;

B. the normal time of vine fruit from germinateing to plucking is probably about 110 days, and the first season, fruit was after artificial effectively management is germinateed from early March and plucked to early July, just carries out large loose water to vine and fills with and execute;

Pinch when c. waiting blade to grow to 4 true leaves, the sublateral shoot being retained in top germinates, and all the other sublateral shoots do bud picking process; Repeatedly manage in this way, first time is stayed 4 true leaves to pinch and smears the tip, and second time stays 4 true leaves to pinch again, and third time stays 3 true leaves to pinch, and stays for the 4th time 2 true leaves to pinch, stays 2 true sheet leaves repeatedly to pinch later at every turn;

D.. when blade tip have two seasons flower bud occurs in batch time, adopt plant modifying agent carry out flower and fruit protecting;

E. carry out fruit thinning, the second season, each strain vine of fruit only stayed 4 string fruits, and often string fruit only stays 50-70 grain grape, then according to the first season of normal management fertilising really.

According to the method described above, viny two seasons fruit bloom in batch from early August and can ripe to go on the market completely before frost by the end of November.

Claims (1)

1. vine two season fruit a management method, it is characterized in that comprising the following steps:
