Description

Method for improving fruit setting rate and/or yield of Muya-Ge apricots
Technical Field
The invention belongs to the technical field of apricot tree planting, and particularly relates to a method for improving fruit set percentage and/or yield of a Muya Kyoho.
Background
The Muya Kya Ge apricot is one of main apricot varieties cultivated in the Kashi region, is a fresh food and dry making dual-purpose variety, has excellent fresh food property and dry making property, and is a local characteristic apricot variety. The existing cultivation area of the prunus armeniaca in the karshi area is 10-12 ten thousand mu, and the prunus armeniaca is an important support column of the local forest and fruit industry. However, farmers who plant the Muya-Ge apricots know that although the flower volume of the tree is large, the natural fruit setting rate is extremely low, the flower and fruit fall easily, and the final yield per mu is only about 200kg, which seriously influences the economic benefit of planting the Muya-Ge apricots. In the traditional production of the Muyage apricot in Xinjiang area, the Saimaiti apricot is mainly used as a pollinator or pollinated by other conventional varieties or commercial pollen, and the problems of low fruit setting rate, low yield and the like in most years still exist. Therefore, how to effectively improve the fruit setting rate of the Manya Kwangsi trees is a technical problem which needs to be solved urgently in the field. Most of the existing methods for improving the fruit set percentage of the Muya ge apricot trees in the field are mainly focused on the aspects of water and fertilizer management, pest and disease control, shaping and trimming, freezing damage prevention in flowering phase and other external environment influences, but the method for improving the fruit set percentage of the Muya ge apricot trees has the defects that the yield cannot be stabilized and the production cost cannot be improved, so that the problem of low fruit set percentage of the Muya ge apricot trees is solved fundamentally, the fruit set percentage of the Muya ge apricot trees is not influenced by external environment factors, and the method is a major problem in the field. The Muya-Ge apricot is different from other apricot varieties in Xinjiang, has strong variety specificity, and is difficult to improve the fruit setting rate of the Muya-Ge apricot by changing the way of pollinating varieties, for example, the fruit setting rate of the Chaotai white apricot can be obviously improved after the Chaotai white apricot and other varieties are used as pollinating trees to pollinate the Chaotai white apricot, but the fruit setting rate is not obviously changed when the Chaotai white apricot is pollinated by pollen of the Chaotai white apricot. Therefore, it is actually very difficult to solve the technical problem of low fruit setting rate of the prunus armeniaca by adjusting pollinated varieties in a conventional manner. Furthermore, how to effectively improve the fruit set percentage of the Muya Gu apricot is a problem in the field.

The technical solutions provided by the present invention are described in detail below with reference to examples, but they should not be construed as limiting the scope of the present invention.
In the following examples, unless otherwise specified, all methods are conventional.
Materials, reagents and the like used in the following examples are commercially available unless otherwise specified.
Example 1
Pollen collection: and (3) selecting strong and strong thick black-leaf apricot branches without plant diseases and insect pests, bringing the branches back to the room for flower forcing, and placing the branches at intervals of 2 meters. Removing anther with tweezers in bud period, spreading on clean white paper, and naturally drying in the shade for 1-2 days. Collecting pollen in a centrifugal tube after the pollen is completely scattered, and storing at a low temperature of-20 ℃ for later use.
A pollination mode: adopting an artificial pollination method, performing pollination in a Muyage apricot test garden before pollination, uniformly mixing the pollen collected in the step with pollen pini according to the proportion of 1; recording the specific pollination number, and counting the fruit setting rate 20 days before harvesting. Fruit set rate (%) = (number of fruit set/number of pollination) × 100.
Example 2
The difference from example 1 is that pollen was collected from late-maturing apricots, and the rest is the same as example 1.
Example 3
Pollen collection: in the bud period, 23 kinds of apricot pollen including apricot red leaves, oxhorn yellow, white apricot huiyang, baidou, cosmic red, long fruit red apricot, sweet jade, xifeng early apricot, maihuang apricot, red jade apricot, daquan apricot, shogao red, egg apricot, big fruit apricot, small red robe, qufuhuang apricot, maeukaryon, mazi apricot, atrial mountain red apricot, tungzhuan red apricot, guozhixian, no. 1 and climbing apricot are collected respectively, and the specific collection mode is the same as that of example 1. The 23 apricot pollen collected above are mixed evenly according to the equal weight ratio, and stored at the low temperature of minus 20 ℃ for standby. The pollination pattern and the rest of the procedure were the same as in example 1.
Comparative example 1
The difference from the embodiment 1 is that the pollen is respectively collected from winter apricot, golden sun, red lotus, akjagele, aixiackjagele, silver fragrant white, joule fat, red jade apricot, thin black leaf apricot, zhang park big-joint apricot, ku che white apricot, saiyi, camel yellow, hua county big-joint apricot, and the rest is the same as the embodiment 1. That is, this comparative example was a parallel experiment of 14 remaining pollinated varieties in the manner of example 1.
Comparative example 2
The difference from example 1 is that the pollen used for artificial pollination is the purchased pollen of Brilliant boy brand (commercial pollen), and the rest is the same as example 1.
The embodiment and the comparative example adopt the same water and fertilizer management and pest control mode, and robust trees with consistent tree age and unified management are selected during pollination, and the direction distribution and the growth conditions of branches are ensured to be as close as possible.
The overall goal of the water and fertilizer management is simplified: with the purposes of quality improvement and efficiency improvement, fertilizer and water are reasonably added around the key fertilizer and water requiring period of the apricot trees. The key period of water and fertilizer management is as follows: fertilizing water after flowers, fruit expanding fertilizing water, flower bud differentiating fertilizing water, base fertilizer applied in autumn and overwintering water; fertilizing water after flowers: the fruit setting rate is improved; fruit expansion and water fertilization: the comprehensive quality of the fruits is improved; flower bud differentiation fertilizer and water: promoting the effective differentiation of flower buds; applying a base fertilizer in autumn: the tree body is enriched and strengthened, and the resistance is improved; overwintering water: the safe overwintering of the tree body is guaranteed.
And (3) pest control mode: biological control based on agricultural control and physical control; and performing general prevention and control in the key prevention and control period according to local pest and disease monitoring information.
